 A notable Bible-fundamentalist Scottish Unitarian was J. S. Hyndman, author of "Lectures on The Principles of Unitarianism" (Alnwick, 1824) This conservative non-Trinitarian presence can be demonstrated by the response in Scotland, relative both to America and to his home town London, of the call of the first Christadelphian John Thomas.The first congregations following Thomas' Socinian and Adventist teachings in 1848-1849 were predominantly Scottish.And while the Christadelphians initially made more of their Millennialist teachings, the christological legacy of 17th century unitarians such as John Biddle is evident and acknowledged.
