Dual speech-forms; obedience of the sinless Son from woman

…as if one might also say that a human’s spirit dwells in him, not being another beside him. And over one person a double-faced form of speech is often brought in for us, and in no way does it wrong the truth. For example, if inspired Scripture should say about God: “He who forms a human’s spirit within him,” yet how is it not clear to all that the spirit formed within him would not be understood as another beside the human? And the blessed David says somewhere: “At night I conversed with my heart, and I stirred my spirit.” Then who was the one conversing with his own heart and probing his own spirit?

But this was already much and far beyond humanity’s measures — for no one is clean from sins… So the God and Father, summing up all things in Christ… “sent forth his Son, born from a woman,” so that taking a body like ours and making it his own, he might be found as a human on earth not knowing sin, and thus having become wholly obedient to God the Father, justify human nature in himself and free it from death’s bonds…
