Unitarianism Defended: A Series of Lectures by Three Protestant Dissenting Ministers of Liverpool

"Unitarianism Defended" by John Hamilton Thom, Henry Giles, and James Martineau is a series of lectures written in the early 19th century. This work presents a defense of Unitarian beliefs in response to a previous series of lectures titled “Unitarianism Confuted,” delivered by a group of Church of England clergymen. The authors strive to articulate and uphold the principles of Unitarianism while challenging the interpretations and criticisms levied against them by their opponents. The opening of the text introduces the context of an ongoing theological debate between Unitarians and Trinitarians in Liverpool, highlighting the defensive position taken by the Unitarian ministers. It establishes the background of the controversy, reflecting on the motivations behind the lectures and setting the tone for the subsequent arguments. The authors express their commitment to presenting a thoughtful analysis of the differing perspectives on Christianity, seeking to clarify misunderstandings surrounding Unitarian beliefs while addressing the critiques posed by the Trinitarian clergy. The Preface reviews previous attacks on Unitarian doctrine and asserts the intention to respond rigorously to those challenges in the forthcoming lectures.
