The Lord had at first a human nature from the mother, of which He
gradually divested Himself while He was in the world. Accordingly He
kept experiencing two states: a state of humiliation or privation, as
long and as far as He was conscious in the human nature from the
mother; and a state of glorification or union with the Divine, as long
and as far as He was conscious in the Humanity received 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 spoke with
the Father as with Himself. In this state He said that the Father was
in Him, and He in the Father, and that the Father and He were one.
The Lord consecutively put off the human nature assumed from the
mother, and put on a Humanity from the Divine in Himself, which is the
Divine Humanity and the Son of God.
