THE LORD MADE HIS HUMAN DIVINE FROM THE DIVINE IN HIMSELF; AND HE THUS BECAME ONE WITH THE FATHER.
It is according to the doctrine of the church received throughout the Christian world, “That our Lord Jesus Christ, the Son of God, is both God and Man; and although He is God and Man, still there are not two, but there is one Christ. He is one, because the Divine took to itself the Human; yea, He is altogether one, for He is one Person: since as soul and body make one man, so God and Man are one Christ.” (These are taken from the Athanasian Creed, which is accepted throughout the Christian world.) These are the essential things therein concerning the union of the Divine and the Human in the Lord. . .
From this it is clearly manifest that it is according to the faith of the Christian Church that the Divine and the Human in the Lord are not two, but one, as the soul and body are one man; and that the Divine in Him took on the Human. From this it follows that the Divine cannot be separated from the Human, nor the Human from the Divine; for to separate them would be like separating soul and body. That it is so, every one will acknowledge who reads what is cited above from two of the Evangelists (Luke 1:26-36, and Matthew 1:18-25), concerning the Lord’s birth; from which it is plain that Jesus was conceived of Jehovah God, and born of virgin Mary; so that the Divine was in Him, and it was his Soul. Now, as his Soul was the Divine itself of the Father, it follows that his Body or Human was also made Divine; for where the one is, the other must be also. Thus and not otherwise are the Father and the Son one; the Father in the Son, and the Son in the father.
Also all things of the Son are the Father’s, and all things of the Father are the Son’s as the Lord Himself teaches in his Word; but how the union was effected will be told in order:
