Now because the Lord had from the beginning a human from the mother, and put this off successively, therefore while He was in the world He had two states, which are called the state of humiliation, and the state of glorification or of union with the Divine which is called the Father,–the state of humiliation so far as and when He was in the human from the mother, and the glorification so far as and when He was in the Human from the Father.
In the state of humiliation He prayed to the Father, as to one other than Himself; but in the state of glorification He spake with the Father as with Himself. In the later state, He said that the Father was in Him, and He in the Father, and that the Father and He were one; but in the state of humiliation He underwent temptations, and suffered the cross, and prayed that the Father would not forsake Him; for the Divine could not be tempted, and still less suffer the cross.
From these things it is now manifest, that by temptations, and continual victories in them and by the passion of the cross which was the last of the temptations, He fully conquered the hells, and fully glorified the Human, as was shown before.
