Unitarianism

At its heart, this is a book about heresy and survival. Unitarianism began as a radical Protestant movement that dared to reject the Trinity, affirming instead the absolute oneness of God. In the 16th and 17th centuries, this was not a mild theological disagreement; it was a position that could get you killed. Tarrant traces this dangerous history from the Polish Brethren and the Unitarian Church of Transylvania through the English dissenters like John Biddle and Theophilus Lindsey, who faced imprisonment and social exclusion for their beliefs. The book follows the movement through the tumultuous period of the Act of Uniformity and the Toleration Act, showing how a community of thinkers maintained their convictions despite official opposition. Key figures emerge as intellectual heroes: Joseph Priestley, whose scientific and theological work helped legitimize rational religion; and John Locke, whose philosophy of conscience provided the intellectual scaffolding for religious freedom. The narrative builds to the establishment of the first permanent Unitarian church in 1774 on Essex Street, London. Written in 1914 with a scholar's precision and a believer's warmth, this book captures not just the history of a movement but its animating spirit: that genuine faith and rigorous reason need not be enemies, and that the individual conscience deserves room to breathe even when the whole world disagrees.
