History

Unitarianism, both as a theology and as a denominational family of churches, was defined and developed in Poland, Transylvania, England, Wales, India, Japan, Jamaica, the United States, and beyond in the 16th century through the present. Although common beliefs existed among Unitarians in each of these regions, they initially grew independently from each other. Only later did they influence one another and accumulate more similarities.

The Ecclesia minor or Minor Reformed Church of Poland, better known today as the Polish Brethren, was born as the result of a controversy that started on January 22, 1556, when Piotr of Goniądz (Peter Gonesius), a Polish student, spoke out against the doctrine of the Trinity during the general synod of the Reformed (Calvinist) churches of Poland held in the village of Secemin. After nine years of debate, in 1565, the anti-Trinitarians were excluded from the existing synod of the Polish Reformed Church (henceforth the Ecclesia maior) and they began to hold their own synods as the Ecclesia minor. Though frequently called " Arians " by those on the outside, the views of Fausto Sozzini (Faustus Socinus) became the standard in the church, and these doctrines were quite removed from Arianism. So important was Socinus to the formulation of their beliefs that those outside Poland usually referred to them as Socinians. The Polish Brethren were disbanded in 1658 by the Sejm (Polish Parliament). They were ordered to convert to Roman Catholicism or leave Poland. Most of them went to Transylvania or Holland, where they embraced the name "Unitarian". Between 1665 and 1668 a grandson of Socinus, Andrzej Wiszowaty Sr., published Bibliotheca Fratrum Polonorum quos Unitarios vocant (Library of the Polish Brethren who are called Unitarians 4 vols. 1665–1669).

The Unitarian Church in Transylvania was first recognized by the Edict of Torda, issued by the Transylvanian Diet under Prince John II Sigismund Zápolya (January 1568), and was first led by Ferenc Dávid (a former Calvinist bishop, who had begun preaching the new doctrine in 1566). The term "Unitarian" first appeared as unitaria religio in a document of the Diet of Lécfalva, Transylvania, on 25 October 1600, though it was not widely used in Transylvania until 1638, when the formal recepta Unitaria Religio was published.

The word Unitarian had been circulating in private letters in England, in reference to imported copies of such publications as the Library of the Polish Brethren who are called Unitarians (1665). Henry Hedworth was the first to use the word "Unitarian" in print in English (1673), and the word first appears in a title in Stephen Nye 's A Brief History of the Unitarians, called also Socinians (1687). The movement gained popularity in England in the wake of the Enlightenment and began to become a formal denomination in 1774 when Theophilus Lindsey organised meetings with Joseph Priestley, founding the first avowedly Unitarian congregation in the country. This occurred at Essex Street Church in London. Official toleration came in 1813.

The first official acceptance of the Unitarian faith on the part of a congregation in America was by King's Chapel in Boston, which settled James Freeman (1759–1835) in 1782, and revised the Prayer Book into a mild Unitarian liturgy in 1785. In 1800, Joseph Stevens Buckminster became minister of the Brattle Street Church in Boston, where his brilliant sermons, literary activities, and academic attention to the German "New Criticism" helped shape the subsequent growth of Unitarianism in New England. Unitarian Henry Ware (1764–1845) was appointed as the Hollis professor of divinity at Harvard College, in 1805. Harvard Divinity School then shifted from its conservative roots to teach Unitarian theology (see Harvard and Unitarianism). Buckminster's close associate William Ellery Channing (1780–1842) was settled over the Federal Street Church in Boston, 1803, and in a few years he became the leader of the Unitarian movement. A theological battle with the Congregational Churches resulted in the formation of the American Unitarian Association at Boston in 1825. Certainly, the unitarian theology was being "adopted" by the Congregationalists from the 1820s onwards. This movement is also evident in England at this time.

The first school founded by the Unitarians in the United States was the Clinton Liberal Institute, in Clinton, Oneida County, New York, founded in 1831.
