Novatian

Habakkuk the prophet says, “God shall come from the south, and the holy one from the dark and dense mountain.” Whom would they have come from the south? If they say that God the Father almighty came, then God the Father came from a place; consequently, he is also enclosed by space and contained within the limits of some abode. Thus the sacrilegious heresy of Sabellius, as we said, takes concrete form because of these people who believe that Christ is not the Son but the Father. It is strange how these heretics, while insisting that Christ is a mere man, make an about-face and acknowledge that Christ is the Father, God almighty.
