Socinianism

Socinianism is a system of Christian doctrine named for Fausto Sozzini (Latin: Faustus Socinus), which was developed among the Polish Brethren in the Minor Reformed Church of Poland during the 15th and 16th centuries and embraced also by the Unitarian Church of Transylvania during the same period. It is most famous for its Nontrinitarian Christology but contains a number of other unorthodox beliefs as well.
