pursuance of the order established by Him from the creation of the world. That is, He was to be conceived by a power produced from Himself; He was to be carried in the womb; He was to be born, and then to grow in wisdom and in love, and so was to approach to union with His Divine origin. Thus God became Man, and Man God.
—True Christian Religion, n. 838
THE LIFE ON EARTH
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.
—Doctrine Concerning the Lord, nn. 29, 35
