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. Beliefs Christology Unitarians charge that the Trinity, unlike unitarianism, fails to adhere to strict monotheism. Unitarians maintain that Jesus was a great man and a prophet of God, perhaps even a supernatural being, but not God himself. They believe Jesus did not claim to be God and that his teachings did not suggest the existence of a triune God. Unitarian Christology can be divided according to whether or not Jesus is believed to have had a pre-human existence. Both forms maintain that God is one being and one "person" and that Jesus is the (or a) Son of God, but generally not God himself. In the early 19th century, Unitarian Robert Wallace identified three particular classes of Unitarian doctrines in history: Arian, which believed in a pre-existence of the Logos; Socinian, which denied his pre-existence, but agreed that Christ should be worshipped; and "Strict Unitarian", which, believing in an "incommunicable divinity of God", denied the worship of "the man Christ." Unitarianism is considered a factor in
