One true church


From Wikipedia, the free encyclopedia

The expression "one true church" refers to an ecclesiological position asserting that Jesus gave his authority in the Great Commission solely to a particular visible Christian institutional church—what is commonly called a denomination. This view is maintained by the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox communion, the Assyrian Church of the East, the Ancient Church of the East, the Christian Churches/Churches of Christ, the Churches of Christ, and the Lutheran Churches, as well as certain Baptists. Each of them maintains that their own specific institutional church (denomination) exclusively represents the one and only original church. The claim to the title of the "one true church" relates to the first of the Four Marks of the Church mentioned in the Nicene Creed: "one, holy, catholic, and apostolic church". As such, it also relates to claims of both catholicity and apostolic succession: asserting inheritance of the spiritual, ecclesiastical and sacramental authority and responsibility that Jesus Christ gave to the apostles.

The concept of schism somewhat moderates the competing claims between some churches—one can potentially repair schism, since they are striving for the same goal. For example, the Catholic and Eastern Orthodox churches each regard the other as schismatic and at very least heterodox, if not heretical, yet both have held dialogues and even partaken in Councils in attempts to resolve the division that exists between them.

Many Mainline Protestants regard all baptized Christians as members of a spiritual—not institutional—"Christian Church" regardless of their differing beliefs; this belief is sometimes referred to by the theological term "invisible church". Some Anglicans of Anglo-Catholic churchmanship espouse a version of branch theory which teaches that the true Christian Church comprises Anglican, Eastern Orthodox, Old Catholic, Oriental Orthodox, Scandinavian Lutheran, Moravian, Persian, and Roman Catholic branches.

Other denominations, such as the Church of Jesus Christ of Latter-day Saints (LDS Church) also claim inheritance of the authority and responsibility that Jesus Christ conferred on the apostles. Other groups, such as Iglesia ni Cristo, believe in a last-messenger doctrine, where no such succession takes place. The Seventh-day Adventist Church regards itself to be the one true church in the sense of being a faithful remnant.

Teachings by denomination

Catholicism

The Roman Catholic Church teaches that Christ founded only "one true Church", and that this one true Church is the Catholic Church with the bishop of Rome (the pope) as its supreme, infallible head and locus of communion. From this follows that it regards itself as "the universal sacrament of salvation for the human race" and the "only true religion".

According to the Catechism of the Catholic Church, Catholic ecclesiology professes the Catholic Church to be the "sole Church of Christ"—i.e., the one true church defined as "one, holy, catholic, and apostolic" in the Four Marks of the Church in the Nicene Creed. The Council of Nicea (AD 325) originally formulated this teaching and ratified the Nicene Creed. The church teaches that only the Catholic Church was founded by Jesus Christ, who appointed the Twelve Apostles to continue his work as the Church's earliest bishops. Catholic belief holds that the Church "is the continuing presence of Jesus on earth", and that all duly-consecrated bishops have a lineal succession from the apostles. In particular, the Bishop of Rome (the Pope), is considered the successor to the apostle Simon Peter, from whom the Pope derives his supremacy over the Church. The 1943 papal encyclical Mystici corporis Christi further describes the Church as the Mystical Body of Christ. Thus the Catholic Church holds that "the one Church of Christ which in the Creed is professed as one, holy, catholic and apostolic ... This Church constituted and organized in the world as a society, subsists in the Catholic Church, which is governed by the successor of Peter and by the Bishops in communion with him." In Humani Generis, Pope Pius XII declared that "the Mystical Body of Christ and the Roman Catholic Church are one and the same thing." The Second Vatican Council repeated this teaching, stating in the Decree on the Eastern Churches: "The Holy Catholic Church, which is the Mystical Body of Christ, is made up of the faithful who are organically united in the Holy Spirit by the same faith, the same sacraments and the same government."

In responding to some questions regarding the doctrine of the Church concerning itself, the Vatican's Sacred Congregation for the Doctrine of the Faith stated, "Clarius dicendum esset veram Ecclesiam esse solam Ecclesiam catholicam romanam..." ("It should be said more clearly that the Roman Catholic Church alone is the true Church..") And it also clarified that the term subsistit in used in reference to the Church in the Second Vatican Council's 1964 decree Lumen gentium "indicates the full identity of the Church of Christ with the Catholic Church".

The 1215 Fourth Lateran Council declared that: "There is one universal Church of the faithful, outside of which there is absolutely no salvation", a statement of what is known as the doctrine of extra Ecclesiam nulla salus.

In the encyclical Mortalium animos of 6 January 1928, Pope Pius XI wrote that "in this one Church of Christ no man can be or remain who does not accept, recognize and obey the authority and supremacy of Peter and his legitimate successors" and quoted the statement of Lactantius: "The Catholic Church is alone in keeping the true worship. This is the fount of truth, this the house of Faith, this the temple of God: if any man enter not here, or if any man go forth from it, he is a stranger to the hope of life and salvation." Accordingly, the Second Vatican Council of 1962–1965 declared: "Whosoever, [...] knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved. In the same document, the Council continued: "The Church recognizes that in many ways she is linked with those who, being baptized, are honored with the name of Christian, though they do not profess the faith in its entirety or do not preserve unity of communion with the successor of Peter." And in a decree on ecumenism, Unitatis redintegratio, it stated: "Catholics must gladly acknowledge and esteem the truly Christian endowments from our common heritage which are to be found among our separated brethren. It is right and salutary to recognise the riches of Christ and virtuous works in the lives of others who are bearing witness to Christ, sometimes even to the shedding of their blood. For God is always wonderful in His works and worthy of all praise."

The Catholic Church teaches that the fullness of the "means of salvation" exists only in the Catholic Church, but the church acknowledges that the Holy Spirit can make use of ecclesial communities separated from itself to "impel towards Catholic unity" and thus bring people to salvation in the Catholic Church ultimately. It teaches that anyone who is saved is saved through the Catholic Church but that people can be saved ex voto and by pre-baptismal martyrdom as well as when conditions of invincible ignorance are present, although invincible ignorance in itself is not a means of salvation.

Roman Catholic theology regards formal schismatics as outside the church, understanding by "formal schismatics" "persons who, knowing the true nature of the Church, have personally and deliberately committed the sin of schism". The situation, for instance, of those who have been brought up from childhood within a group not in communion with Rome, and who are acting in good faith and have maintained almost the entirety of the orthodox faith, differs. This nuanced view applies especially to the churches of Eastern Christianity, more particularly still to the Eastern Orthodox Church, though doctrinal impediments still remain, such as disagreement over the primacy of the Roman See, papal infallibility, the nature of Purgatory, indulgences, the Immaculate Conception, and a few other important doctrines.

Orthodoxy

The Eastern Orthodox Church (officially the Orthodox Catholic Church) identifies its confederative communion of Orthodox churches as the "One, Holy, Catholic, and Apostolic Church" of the Nicene-Constantinopolitan Creed and applies this title in conciliar and other official documents, for instance, in the Constantinople synods held in 1836 and 1838 and in correspondence with Pope Pius IX (r. 1846–1878) and with Pope Leo XIII (r. 1878–1903).

Lutheranism

...one holy Church is to continue forever. The Church is the congregation of saints, in which the Gospel is rightly taught and the Sacraments are rightly administered. — Augsburg Confession

The Lutheran Church views itself as the "main trunk of the historical Christian Tree" founded by Christ and the Apostles, holding that during the Reformation, the Church of Rome fell away. The Augsburg Confession found within the Book of Concord, a compendium of belief of the Lutheran Churches, teaches that "the faith as confessed by Luther and his followers is nothing new, but the true Catholic faith, and that their churches represent the true catholic or universal church". When the Lutherans presented the Augsburg Confession to Charles V, Holy Roman Emperor in 1530, they believe to have "showed that each article of faith and practice was true first of all to Holy Scripture, and then also to the teaching of the church fathers and the councils".

Lutheran theology therefore holds that:

There can only be one true visible Church. Of this our Catechism speaks in Question 192: "Whom do we call the true visible Church?" Answer: "The whole number of those who have, teach and confess the entire doctrine of the Word of God in all its purity, and among whom the Sacraments are duly administered according to Christ's institution." That there can be but one true visible Church, and that, therefore, one is not just as good as another stands to reason because there is only one truth, one Bible, one Word of God. Evidently that Church which teaches this truth, the whole truth, and nothing but the truth, is the true visible Church. Christ says John 8, 31. 32: "If ye continue in My Word, then are ye My disciples indeed; and ye shall know the truth, and the truth shall make you free." Again Christ says Matt. 28, 20: "Teaching them to observe all things whatsoever I have commanded you." Whatsoever He has commanded us, His Word, and nothing else, we should teach. And again, all things which He has commanded us we should teach. That, therefore is the true visible Church which does this. But that all visible Churches do not this is plain from the fact that they do not agree among themselves. If every Church would teach the whole truth and nothing but the truth as God has revealed it, there could be no difference. So, then, by calling other denominations Churches, we do not mean to say that one Church is just as good as another. Only that one is the true visible Church which teaches and confesses the entire doctrine of the Word of God in all its purity, and in whose midst the Sacraments are duly administered according to Christ's institution. Of all Churches, this can only be said of our Lutheran Church.

Laestadian Lutherans, in particular, emphasize this belief.

Baptists

Graph from The Trail of Blood, a popular Baptist book that teaches the doctrine of Baptist successionism.

Many Baptists, who uphold the doctrine of Baptist successionism (also known as Landmarkism), "argue that their history can be traced across the centuries to New Testament times" and "claim that Baptists have represented the true church" that "has been, present in every period of history". These Baptists maintain that those who held their views throughout history, including the "Montanists, Novatians, Patarenes, Bogomils, Paulicians, Arnoldists, Henricians, Albigenses, and Waldenses", were persecuted for their faith, a belief that these Baptists maintain to be "grand distinguishing mark of the true church". In the introduction of The Trail of Blood, a Baptist text that explicates the doctrine of Baptist succession, Clarence Walker states that "The history of Baptists, he discovered, was written in blood. They were the hated people of the Dark Ages. Their preachers and people were put into prison and untold numbers were put to death." J. M. Carroll, the author of the said text The Trail of Blood, also appeals to historian Johann Lorenz von Mosheim, who stated "Before the rise of Luther and Calvin, there lay secreted in almost all the countries of Europe persons who adhered tenaciously to the principles of modern Dutch Baptists." Walter B. Shurden, the founding executive director of the Center for Baptist Studies at Mercer University, writes that the theology of Landmarkism, which he states is integral of the history of the Southern Baptist Convention, upholds the ideas that "Only Baptist churches can trace their lineage in uninterrupted fashion back to the New Testament, and only Baptist churches therefore are true churches." In addition Shurden writes that Baptists who uphold successionism believe that "only a true church-that is, a Baptist church-can legitimately celebrate the ordinances of baptism and the Lord's Supper. Any celebration of these ordinances by non-Baptists is invalid."

Baptists who uphold this ecclesiology also do not characterize themselves as being a Protestant church due to their belief that "they did not descend from those churches that broke away in protest from the church of Rome. Rather, they had enjoyed a continuous historical existence from the time of the very first church in the New Testament days." These views are generally no longer widely held in the Southern Baptist Convention although they are still taught by some Southern Baptist Churches and many independent Baptist churches, Primitive Baptists (Reformed Baptists), and some "congregations affiliated with the American Baptist Association."

Anabaptists

Amish

The Amish, as with other Anabaptist Christians, believe that "the established church became corrupt, ineffectual, and displeasing to God." The Amish believe that the true church is pure and separate from the world:

Amish fraternity is based upon the understanding of the church as a redemptive community. To express this corporateness they use the German term Gemeinde or the shorter dialect version pronounced Gemee. This concept expresses all the connotations of church, congregation, and community. The true church, they believe, had its origin in God's plan, and after the end of time the church will coexist with God through eternity. The true church is to be distinguished from the "fallen church". ... The church of God is composed of those who "have truly repented and rightly believed; who are rightly baptized ... and incorporated into the communion of saints on earth." The true church is "a chosen generation, a royal priesthood, an holy nation," and "a congregation of the righteous." The church of God is separate and completely different from the "bind perverted world." Furthermore, the church is "known by her evangelical faith, doctrine, love, and godly conversation; also by her pure walk and practice, and her observances of the true ordinances of Christ." The church must be "pure, unspotted and without blemish" (Eph. 5:27), capable of enforcing disciplinary measures to insure purity of life and separation from the world.

Holdeman Mennonites

The Holdeman Mennonites teach that their Church of God in Christ is the one true church. Anabaptist theologian Donald Kraybill writes:

Although similar in some ways to other conservative Mennonite groups, the Holdeman church teaches that they are the one true church of Christ. Their doctrine of the one true church, based on Matthew 16:18 and other Scriptures, emphasizes the succession of true doctrine, practice, and teachers through the centuries, and the authority of the church under Christ.

Quakers

As described in the tract The Glory of the True Church by Francis Howgill, the Religious Society of Friends traditionally believed that after the Apostolic Era, the "true Church fled into the wilderness" and "the false Church came into visibility". George Fox and his followers "believed that they were called to carry out the true reformation, to restore apostolic Christianity, and to make a fresh beginning". As such, "The Quaker community was the one true Church, and consequently those converted by Quaker preaching were expected to join it." Among some Quakers, there became a "shift from being the one and only True Church to being a part of the True Church" and so "marriage with non-Quakers became accepted by many in the Quaker community", though "they still had to marry within the Meeting House, as well as gain approbation."

Methodism

Methodist preachers are known for promulgating the doctrines of the new birth and entire sanctification to the public at events such as tent revivals and camp meetings, which they believe is the reason that God raised them up into existence.

Methodists affirm belief in "the one true Church, Apostolic and Universal", viewing their Churches as constituting a "privileged branch of this true church". With regard to the position of Methodism within Christendom, the founder of the movement "John Wesley once noted that what God had achieved in the development of Methodism was no mere human endeavor but the work of God. As such it would be preserved by God so long as history remained." Calling it "the grand depositum" of the Methodist faith, Wesley specifically taught that the propagation of the doctrine of entire sanctification was the reason that God raised up the Methodists in the world.

Restorationism

Restorationism is a broad category of churches, originating during the Second Great Awakening, that characterize themselves as a return to very early Christianity after the true faith was lost in a Great Apostasy. Prominent among these groups are the Christian churches and churches of Christ, the Churches of Christ (Stone-Campbell movement), the Christadelphians, and the Latter Day Saint movement (Mormonism). The idea of "restoration" was a popular theme of the time of the founding of these branches, and developed an independent expression in both. In the Stone-Campbell movement, the idea of restoration was combined with Enlightenment rationalism, "precluding emotionalism, spiritualism, or any other phenomena that could not be sustained by rational appeals to the biblical text."

Seventh-Day Adventist

The Seventh-Day Adventist Church (SDA Church) holds itself to be the one true church. It specifically teaches that "it is the 'final remnant' of His true church [spanning] the centuries". Seventh-day Adventist eschatology promulgates the idea that in the end times, there will be a "growing opposition between the 'true' church and the 'apostate' church." According to Seventh-day Adventist theology, these apostates are referred to as "Babylon", which they state is an amalgam of religions (including other Christian denominations) that worship on Sunday rather than the Lord's Sabbath, Saturday (Exodus 20:8–11). The SDA Church, in their view, "has drawn substantially on the biblical text, especially the books of Daniel and Revelation, to argue for its own status as the true remnant church which has a divine commission both to exist and to preach its apocalyptic message to the world at large."

Christian Conventions

Some small epsicopal church groups, such as the "Workers and Friends", represent themselves as nondenominational and hold all other churches to be false.

Latter Day Saint movement

In 1830, Joseph Smith established the Church of Christ in the belief that it was a restoration of original Christianity. In 1831 he declared it to be "the only true and living church upon the face of the whole earth". Smith later reported in some versions of his First Vision in his teenage years, Jesus had told him that all churches that then existed "were all wrong; [and] that all their creeds were an abomination in his sight". The Latter Day Saints combined their religion with "the spirit of nineteenth-century Romanticism" and, as a result, "never sought to recover the forms and structures of the ancient church as ends in themselves" but "sought to restore the golden age, recorded in both Old Testament and New Testament, when God broke into human history and communed directly with humankind."

The predominant organization within the movement is the LDS Church, which continues to teach that it is "the only true and living church upon the face of the whole earth". The church teaches that all people who achieve the highest level of salvation must be baptized by one who holds the proper authority to perform such an ordinance; however, those who missed that opportunity in their lifetime may be included through a proxy baptism for the dead, in which a church member is baptized on their behalf inside a temple.

Most other Latter Day Saint churches claim to be the rightful continuation or successor of the church Smith established and therefore claim to be the one true church. However, the Community of Christ, the second-largest Latter Day Saint church, has recently de-emphasized this belief in favor of a position that the Community of Christ "is part of the whole body of Christ". The church's canonized Doctrine and Covenants continues to contain the declaration that the church is the "only true and living church".

Iglesia ni Cristo

The Iglesia ni Cristo (INC) a Philippine-based Christian religion, like other restorationist groups, professes that it is the one church founded by Jesus. Adherents hold that the Iglesia ni Cristo ("Church of Christ" in Tagalog) is the only true church of Jesus Christ as restored through a human instrument (sugo) Felix Manalo. The church recognizes Jesus Christ as the founder of the Christian Church. Meanwhile, its reestablishment is seen as the signal for the end of days. They believe that the church was apostatized by the 1st or 4th century due to false teachings. The INC says that this apostate church is the Roman Catholic Church.

Fear not for I am with you; I will bring your descendants from the east, And gather you from the west; I will say to the north, 'Give them up!' And to the south, 'Do not keep them back!' Bring My sons from afar, And My daughters from the ends of the earth.

Members believe that the Iglesia ni Cristo is the fulfillment of the passage above. Based from their doctrines, "ends of the earth" pertains to the time the true church would be restored from apostasy and "east" refers to the Philippines where the "Church of Christ" would be founded. The INC teaches that its members constitute the "elect of God" and there is no salvation outside the INC. Faith alone is insufficient for salvation. The Iglesia ni Cristo says that the official name of the true church is "Church of Christ". The two passages often cited by INC to support this are Romans 16:16 "Greet one another with a holy kiss. All the churches of Christ greet you" and the George Lamsa translation of Acts 20:28: "Take heed therefore ... to feed the church of Christ which he has purchased with his blood."

Antimony is a chemical element with the symbol Sb (from Latin stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. The earliest known description of the metalloid in the West was written in 1540 by Vannoccio Biringuccio.

China is the largest producer of antimony and its compounds, with most production coming from the Xikuangshan Mine in Hunan. The industrial methods for refining antimony from stibnite are roasting followed by reduction with carbon, or direct reduction of stibnite with iron.

The largest applications for metallic antimony are in alloys with lead and tin, which have improved properties for solders, bullets, and plain bearings. It improves the rigidity of lead-alloy plates in lead–acid batteries. Antimony trioxide is a prominent additive for halogen-containing flame retardants. Antimony is used as a dopant in semiconductor devices.

Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic. Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb2O3.

Antimony is a silvery, lustrous gray metalloid with a Mohs scale hardness of 3, which is too soft to mark hard objects. Coins of antimony were issued in China's Guizhou province in 1931; durability was poor, and minting was soon discontinued. Antimony is resistant to attack by acids.

Four allotropes of antimony are known: a stable metallic form, and three metastable forms (explosive, black, and yellow). Elemental antimony is a brittle, silver-white, shiny metalloid. When slowly cooled, molten antimony crystallizes into a trigonal cell, isomorphic with the gray allotrope of arsenic. A rare explosive form of antimony can be formed from the electrolysis of antimony trichloride. When scratched with a sharp implement, an exothermic reaction occurs and white fumes are given off as metallic antimony forms; when rubbed with a pestle in a mortar, a strong detonation occurs. Black antimony is formed upon rapid cooling of antimony vapor. It has the same crystal structure as red phosphorus and black arsenic; it oxidizes in air and may ignite spontaneously. At 100 °C, it gradually transforms into the stable form. The yellow allotrope of antimony is the most unstable; it has been generated only by oxidation of stibine (SbH3) at −90 °C. Above this temperature and in ambient light, this metastable allotrope transforms into the more stable black allotrope.

Elemental antimony adopts a layered structure (space group R3m No. 166) whose layers consist of fused, ruffled, six-membered rings. The nearest and next-nearest neighbors form an irregular octahedral complex, with the three atoms in each double layer slightly closer than the three atoms in the next. This relatively close packing leads to a high density of 6.697 g/cm3, but the weak bonding between the layers leads to the low hardness and brittleness of antimony.

Isotopes

Antimony has two stable isotopes: 121Sb with a natural abundance of 57.36% and 123Sb with a natural abundance of 42.64%. It also has 35 radioisotopes, of which the longest-lived is 125Sb with a half-life of 2.75 years. In addition, 29 metastable states have been characterized. The most stable of these is 120m1Sb with a half-life of 5.76 days. Isotopes that are lighter than the stable 123Sb tend to decay by β+ decay, and those that are heavier tend to decay by β decay, with some exceptions. Antimony is the lightest element to have an isotope with an alpha decay branch, excluding 8Be and other light nuclides with beta-delayed alpha emission.

Occurrence

Stibnite, China CM29287 Carnegie Museum of Natural History specimen on display in Hillman Hall of Minerals and Gems

The abundance of antimony in the Earth's crust is estimated at 0.2 parts per million, comparable to thallium at 0.5 parts per million and silver at 0.07 ppm. Even though this element is not abundant, it is found in more than 100 mineral species. Antimony is sometimes found natively (e.g. on Antimony Peak), but more frequently it is found in the sulfide stibnite (Sb2S3) which is the predominant ore mineral.

Compounds

Antimony compounds are often classified according to their oxidation state: Sb(III) and Sb(V). The +5 oxidation state is more common.

Oxides and hydroxides

Antimonides, hydrides, and organoantimony compounds

Compounds in this class generally are described as derivatives of Sb3−. Antimony forms antimonides with metals, such as indium antimonide (InSb) and silver antimonide (Ag

Stibine can also be produced by treating Sb3+
salts with hydride reagents such as sodium borohydride. Stibine decomposes spontaneously at room temperature. Because stibine has a positive heat of formation, it is thermodynamically unstable and thus antimony does not react with hydrogen directly.

Organoantimony compounds are typically prepared by alkylation of antimony halides with Grignard reagents. A large variety of compounds are known with both Sb(III) and Sb(V) centers, including mixed chloro-organic derivatives, anions, and cations. Examples include triphenylstibine (Sb(C6H5)3) and pentaphenylantimony (Sb(C6H5)5).

History

One of the alchemical symbols for antimony

Antimony(III) sulfide, Sb2S3, was recognized in predynastic Egypt as an eye cosmetic (kohl) as early as about 3100 BC, when the cosmetic palette was invented.

An artifact, said to be part of a vase, made of antimony dating to about 3000 BC was found at Telloh, Chaldea (part of present-day Iraq), and a copper object plated with antimony dating between 2500 BC and 2200 BC has been found in Egypt. Austen, at a lecture by Herbert Gladstone in 1892, commented that "we only know of antimony at the present day as a highly brittle and crystalline metal, which could hardly be fashioned into a useful vase, and therefore this remarkable 'find' (artifact mentioned above) must represent the lost art of rendering antimony malleable."

The British archaeologist Roger Moorey was unconvinced the artifact was indeed a vase, mentioning that Selimkhanov, after his analysis of the Tello object (published in 1975), "attempted to relate the metal to Transcaucasian natural antimony" (i.e. native metal) and that "the antimony objects from Transcaucasia are all small personal ornaments." This weakens the evidence for a lost art "of rendering antimony malleable."

The Roman scholar Pliny the Elder described several ways of preparing antimony sulfide for medical purposes in his treatise Natural History, around 77 AD. Pliny the Elder also made a distinction between "male" and "female" forms of antimony; the male form is probably the sulfide, while the female form, which is superior, heavier, and less friable, has been suspected to be native metallic antimony.

The Greek naturalist Pedanius Dioscorides mentioned that antimony sulfide could be roasted by heating by a current of air. It is thought that this produced metallic antimony.

The Italian metallurgist Vannoccio Biringuccio described a procedure to isolate antimony.

Antimony was frequently described in alchemical manuscripts, including the Summa Perfectionis of Pseudo-Geber, written around the 14th century. A description of a procedure for isolating antimony is later given in the 1540 book De la pirotechnia by Vannoccio Biringuccio, predating the more famous 1556 book by Agricola, De re metallica. In this context Agricola has been often incorrectly credited with the discovery of metallic antimony. The book Currus Triumphalis Antimonii (The Triumphal Chariot of Antimony), describing the preparation of metallic antimony, was published in Germany in 1604. It was purported to be written by a Benedictine monk, writing under the name Basilius Valentinus in the 15th century; if it were authentic, which it is not, it would predate Biringuccio.

The metal antimony was known to German chemist Andreas Libavius in 1615 who obtained it by adding iron to a molten mixture of antimony sulfide, salt and potassium tartrate. This procedure produced antimony with a crystalline or starred surface.

With the advent of challenges to phlogiston theory, it was recognized that antimony is an element forming sulfides, oxides, and other compounds, as do other metals.

The first discovery of naturally occurring pure antimony in the Earth's crust was described by the Swedish scientist and local mine district engineer Anton von Swab in 1783; the type-sample was collected from the Sala Silver Mine in the Bergslagen mining district of Sala, Västmanland, Sweden.

Etymology

The medieval Latin form, from which the modern languages and late Byzantine Greek take their names for antimony, is antimonium. The origin of this is uncertain; all suggestions have some difficulty either of form or interpretation. The popular etymology, from ἀντίμοναχός anti-monachos or French antimoine, still has adherents; this would mean "monk-killer", and is explained by many early alchemists being monks, and antimony being poisonous. However, the low toxicity of antimony (see below) makes this unlikely.

Another popular etymology is the hypothetical Greek word ἀντίμόνος antimonos, "against aloneness", explained as "not found as metal", or "not found unalloyed". Edmund Oscar von Lippmann conjectured a hypothetical Greek word ανθήμόνιον anthemonion, which would mean "floret", and cites several examples of related Greek words (but not that one) which describe chemical or biological efflorescence.

The early uses of antimonium include the translations, in 1050–1100, by Constantine the African of Arabic medical treatises. Several authorities believe antimonium is a scribal corruption of some Arabic form; Meyerhof derives it from ithmid; other possibilities include athimar, the Arabic name of the metalloid, and a hypothetical as-stimmi, derived from or parallel to the Greek.

The standard chemical symbol for antimony (Sb) is credited to Jöns Jakob Berzelius, who derived the abbreviation from stibium.

The ancient words for antimony mostly have, as their chief meaning, kohl, the sulfide of antimony. The Egyptians called antimony mśdmt or stm.

The Arabic word for the substance, as opposed to the cosmetic, can appear as إثمد ithmid, athmoud, othmod, or uthmod. Littré suggests the first form, which is the earliest, derives from stimmida, an accusative for stimmi. The Greek word, στίμμι (stimmi) is used by Attic tragic poets of the 5th century BC, and is possibly a loan word from Arabic or from Egyptian stm.

Production

Process

The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals. Antimony can be isolated from the crude antimony sulfide by reduction with scrap iron:

Sb

+ 3 Fe → 2 Sb + 3 FeS

The sulfide is converted to an oxide by roasting. The product is further purified by vaporizing the volatile antimony(III) oxide, which is recovered. This sublimate is often used directly for the main applications, impurities being arsenic and sulfide. Antimony is isolated from the oxide by a carbothermal reduction:

2 Sb

The lower-grade ores are reduced in blast furnaces while the higher-grade ores are reduced in reverberatory furnaces.

Top producers and production volumes

In 2022, according to the US Geological Survey, China accounted for 54.5% of total antimony production, followed in second place by Russia with 18.2% and Tajikistan with 15.5%.

 Myanmar 4,000 3.6
 Australia 4,000 3.6
Top 5 105,000 95.5
Total world 110,000 100.0

Chinese production of antimony is expected to decline in the future as mines and smelters are closed down by the government as part of pollution control. Especially due to an environmental protection law having gone into effect in January 2015 and revised "Emission Standards of Pollutants for Stanum, Antimony, and Mercury" having gone into effect, hurdles for economic production are higher.

Reported production of antimony in China has fallen and is unlikely to increase in the coming years, according to the Roskill report. No significant antimony deposits in China have been developed for about ten years, and the remaining economic reserves are being rapidly depleted.

Supply risk

For antimony-importing regions such as Europe and the U.S., antimony is considered to be a critical mineral for industrial manufacturing that is at risk of supply chain disruption. With global production coming mainly from China (74%), Tajikistan (8%), and Russia (4%), these sources are critical to supply.

  • European Union: Antimony is considered a critical raw material for defense, automotive, construction and textiles. The E.U. sources are 100% imported, coming mainly from Turkey (62%), Bolivia (20%) and Guatemala (7%).
  • United Kingdom: The British Geological Survey's 2015 risk list ranks antimony second highest (after rare earth elements) on the relative supply risk index.
  • United States: Antimony is a mineral commodity considered critical to the economic and national security. In 2022, no antimony was mined in the U.S.

Applications

Approximately 48% of antimony is consumed in flame retardants, 33% in lead–acid batteries, and 8% in plastics.

Flame retardants

Antimony is mainly used as the trioxide for flame-proofing compounds, always in combination with halogenated flame retardants except in halogen-containing polymers. The flame retarding effect of antimony trioxide is produced by the formation of halogenated antimony compounds, which react with hydrogen atoms, and probably also with oxygen atoms and OH radicals, thus inhibiting fire. Markets for these flame-retardants include children's clothing, toys, aircraft, and automobile seat covers. They are also added to polyester resins in fiberglass composites for such items as light aircraft engine covers. The resin will burn in the presence of an externally generated flame, but will extinguish when the external flame is removed.

Alloys

Antimony forms a highly useful alloy with lead, increasing its hardness and mechanical strength. For most applications involving lead, varying amounts of antimony are used as alloying metal. In lead–acid batteries, this addition improves plate strength and charging characteristics. For sailboats, lead keels are used to provide righting moment, ranging from 600 lbs to over 200 tons for the largest sailing superyachts; to improve hardness and tensile strength of the lead keel, antimony is mixed with lead between 2% and 5% by volume. Antimony is used in antifriction alloys (such as Babbitt metal), in bullets and lead shot, electrical cable sheathing, type metal (for example, for linotype printing machines), solder (some "lead-free" solders contain 5% Sb), in pewter, and in hardening alloys with low tin content in the manufacturing of organ pipes.

Other applications

InSb infrared detector manufactured by Mullard in the 1960s.

Three other applications consume nearly all the rest of the world's supply. One application is as a stabilizer and catalyst for the production of polyethylene terephthalate. Another is as a fining agent to remove microscopic bubbles in glass, mostly for TV screens – antimony ions interact with oxygen, suppressing the tendency of the latter to form bubbles. The third application is pigments.

In the 1990s antimony was increasingly being used in semiconductors as a dopant in n-type silicon wafers for diodes, infrared detectors, and Hall-effect devices. In the 1950s, the emitters and collectors of n-p-n alloy junction transistors were doped with tiny beads of a lead-antimony alloy. Indium antimonide (InSb) is used as a material for mid-infrared detectors.

Biology and medicine have few uses for antimony. Treatments containing antimony, known as antimonials, are used as emetics. Antimony compounds are used as antiprotozoan drugs. Potassium antimonyl tartrate, or tartar emetic, was once used as an anti-schistosomal drug from 1919 on. It was subsequently replaced by praziquantel. Antimony and its compounds are used in several veterinary preparations, such as anthiomaline and lithium antimony thiomalate, as a skin conditioner in ruminants. Antimony has a nourishing or conditioning effect on keratinized tissues in animals.

Antimony-based drugs, such as meglumine antimoniate, are also considered the drugs of choice for treatment of leishmaniasis in domestic animals. Besides having low therapeutic indices, the drugs have minimal penetration of the bone marrow, where some of the Leishmania amastigotes reside, and curing the disease – especially the visceral form – is very difficult. Elemental antimony as an antimony pill was once used as a medicine. It could be reused by others after ingestion and elimination.

Antimony(III) sulfide is used in the heads of some safety matches. Antimony sulfides help to stabilize the friction coefficient in automotive brake pad materials. Antimony is used in bullets, bullet tracers, paint, glass art, and as an opacifier in enamel. Antimony-124 is used together with beryllium in neutron sources; the gamma rays emitted by antimony-124 initiate the photodisintegration of beryllium. The emitted neutrons have an average energy of 24 keV. Natural antimony is used in startup neutron sources.

Historically, the powder derived from crushed antimony (kohl) has been applied to the eyes with a metal rod and with one's spittle, thought by the ancients to aid in curing eye infections. The practice is still seen in Yemen and in other Muslim countries.

Precautions

Antimony and many of its compounds are toxic, and the effects of antimony poisoning are similar to arsenic poisoning. The toxicity of antimony is far lower than that of arsenic; this might be caused by the significant differences of uptake, metabolism and excretion between arsenic and antimony. The uptake of antimony(III) or antimony(V) in the gastrointestinal tract is at most 20%. Antimony(V) is not quantitatively reduced to antimony(III) in the cell (in fact antimony(III) is oxidised to antimony(V) instead).

Since methylation of antimony does not occur, the excretion of antimony(V) in urine is the main way of elimination. Like arsenic, the most serious effect of acute antimony poisoning is cardiotoxicity and the resulted myocarditis, however it can also manifest as Adams–Stokes syndrome which arsenic doesn't. Reported cases of intoxication by antimony equivalent to 90 mg antimony potassium tartrate dissolved from enamel has been reported to show only short term effects. An intoxication with 6 g of antimony potassium tartrate was reported to result in death after 3 days.

Inhalation of antimony dust is harmful and in certain cases may be fatal; in small doses, antimony causes headaches, dizziness, and depression. Larger doses such as prolonged skin contact may cause dermatitis, or damage the kidneys and the liver, causing violent and frequent vomiting, leading to death in a few days.

Antimony is incompatible with strong oxidizing agents, strong acids, halogen acids, chlorine, or fluorine. It should be kept away from heat.

Antimony leaches from polyethylene terephthalate (PET) bottles into liquids. While levels observed for bottled water are below drinking water guidelines, fruit juice concentrates (for which no guidelines are established) produced in the UK were found to contain up to 44.7 µg/L of antimony, well above the EU limits for tap water of 5 µg/L. The guidelines are:

The tolerable daily intake (TDI) proposed by WHO is 6 µg antimony per kilogram of body weight. The immediately dangerous to life or health (IDLH) value for antimony is 50 mg/m3.

Toxicity

Certain compounds of antimony appear to be toxic, particularly antimony trioxide and antimony potassium tartrate. Effects may be similar to arsenic poisoning. Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin, gastrointestinal symptoms, and cardiac arrhythmias. In addition, antimony trioxide is potentially carcinogenic to humans.

Adverse health effects have been observed in humans and animals following inhalation, oral, or dermal exposure to antimony and antimony compounds. Antimony toxicity typically occurs either due to occupational exposure, during therapy or from accidental ingestion. It is unclear if antimony can enter the body through the skin. The presence of low levels of antimony in saliva may also be associated with dental decay.
