Because "human nature was assumed, not absorbed", 97 in the mysterious Union of the Incarnation, the Church was led over the course of centuries to confess the full Reality of Christ's human Soul, with its operations of intellect and will, and of his human body. In parallel fashion, she had to recall on each occasion that Christ's human nature belongs, as his own, to the divine perSon of the Son of God, who assumed it. Everything that Christ is and does in this nature derives from "one of the Trinity".
