We know also that the Saviour often speaks as man. For His divine nature has human nature joined to it, yet you would not, because of His clothing Himself with a body, be ignorant that He was God. But what do they answer to this, who wish to make out a substance of evil, but form to themselves another God, other than the true Father of Christ? And they say that he is unbegotten, the creator of evil and prince of iniquity, as well as the maker of the world’s fabric. (Gen. 1:1.) Now our Lord, affirming the word of Moses, says, I give thanks unto thee, Father, Lord of heaven and earth.
