The term Unitarian entered the English language via Henry Hedworth, who applied it to the teachings of Laelio Sozzini and the Polish Socinians. Unitarian churches were formally established in Transylvania and Poland (by the Socinians) in the second half of the 16th Century.[26] There, the first doctrines of religious freedom in Europe were established under the jurisdiction of John Sigismund, Transylvania's first Unitarian king. The early Unitarian church not only rejected the Trinity, but also the pre-existence of Christ as well as, in many cases, predestination and original sin as put forward by Augustine of Hippo, and the substitutionary atonement of Christ developed by Anselm of Canterbury and John Calvin. There were several different forms of Christology in the beginnings of the Unitarian movement; ultimately, the dominant Christology became psilanthropism: that Jesus was a man, but one with a unique relationship to God.
