Tertullian

“ Very well, say you; since we on our side affirm our doctrine in precisely the same terms which you use on your side respecting the Son, we are not guilty of blasphemy against the Lord God, for we do not maintain that He died after the divine nature, but only after the human. ”

“ The heretics, indeed, fearing to incur direct blasphemy against the Father, hope to diminish it by this expedient: they grant us so far that the Father and the Son are Two; adding that, since it is the Son indeed who suffers, the Father is only His fellow-sufferer. [7] But how absurd are they even in this conceit! For what is the meaning of “fellow-suffering,” but the endurance of suffering along with another? Now if the Father is incapable of suffering, He. is incapable of suffering in company with another; otherwise, if He can suffer with another, He is of course capable of suffering. ”

“ Now, although when two substances are alleged to be in Christ—namely, the divine and the human—it plainly follows that the divine nature is immortal, and that which is human is mortal, it is manifest in what sense he declares “Christ died”—even in the sense in which He was flesh and Man and the Son of Man, not as being the Spirit and the Word and the Son of God. ”
