In approximately 318 AD there arose a doctrine that became known as Arianism, named after Arius, a priest in Alexandria, Egypt, who taught that Jesus was the Son of God, but not eternal, nor equal to the Father. Arius wrote, “There was once when he was not”. This position was denounced in 325 AD at the First Nicene Council.
Juxtaposed to this belief is the doctrine that the incarnation of Jesus is God’s supreme Theophanic self-revelation to mankind.
So which is it? Was Jesus a created being, or is He the everlasting God?
