[The Muslims] call us Hetaeriasts, or Associators, because, they say, we introduce an associate with God by declaring Christ to the Son of God and God. We say to them in rejoinder: ‘The Prophets and the Scriptures have delivered this to us, and you, as you persistently maintain, accept the Prophets. So, if we wrongly declare Christ to be the Son of God, it is they who taught this and handed it on to us.’
But some of them say that it is by misinterpretation that we have represented the Prophets as saying such things, while others say that the Hebrews hated us and deceived us by writing in the name of the Prophets so that we might be lost. And again we say to them: ‘As long as you say that Christ is the Word of God and Spirit, why do you accuse us of being Hetaeriasts? For the word, and the spirit, is inseparable from that in which it naturally has existence. Therefore, if the Word of God is in God, then it is obvious that He is God. If, however, He is outside of God, then, according to you, God is without word and without spirit. Consequently, by avoiding the introduction of an associate with God you have mutilated Him. It would be far better for you to say that He has an associate than to mutilate Him, as if you were dealing with a stone or a piece of wood or some other inanimate object. Thus, you speak untruly when you call us Hetaeriasts; we retort by calling you Mutilators of God.
