Arianism

Arian concept of Christ
wikipedia

Arianism is the theological teaching attributed to Arius (ca. AD 250–336), a Christian presbyter from Alexandria, Egypt, concerning the relationship of the entities of the Trinity ('God the Father', 'God the Son' and 'God the Holy Spirit') and the precise nature of the Son of God. Deemed a heretic by the First Council of Nicaea of 325, Arius was later exonerated in 335 at the First Synod of Tyre,[1] and then, after his death, pronounced a heretic again at the First Council of Constantinople of 381.[2] The Roman Emperors Constantius II (337–361) and Valens (364–378) were Arians or Semi-Arians. The Arian concept of Christ is that the Son of God did not always exist, but was created by—and is therefore distinct from and inferior to—God the Father. This belief is grounded in John 14:28 "Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I."[3]
