There enters then these lower parts of the world the Son of God, descending from His heavenly home and yet not quitting His Father’s glory, begotten in a new order by a new nativity. In a new order, because being invisible in His own nature, He became visible in ours, and He whom nothing could contain was content to be contained: abiding before all time He began to be in time: the Lord of all things, He obscured His immeasurable majesty and took on Him the form of a servant: being God that cannot suffer, He did not disdain to be man that can, and, immortal as He is, to subject Himself to the laws of death. From the mother of the Lord was received nature, not faultiness: nor in the Lord Jesus Christ, born of the Virgin’s womb, does the wonderfulness of His birth make His nature unlike ours. For He who is true God is also true man: and in this union there is no lie, since the humility of manhood and the loftiness of the Godhead both meet there. For as God is not changed by the showing of pity, so man is not swallowed up by the dignity. For each form does what is proper to it with the co-operation of the other; that is the Word performing what appertains to the Word, and the flesh carrying out what appertains to the flesh. One of them sparkles with miracles, the other succumbs to injuries. And as the Word does not cease to be on an equality with His Father’s glory, so the flesh does not forego the nature of our race. For it must again and again be repeated that one and the same is truly Son of God and truly son of man. God in that in the beginning was the Word, and the Word was with God, and the Word was God (John 1:1); man in that the Word became flesh and dwelt in us. God in that all things were made by Him, and without Him was nothing made: man in that He was made of a woman, made under law Galatians 4:4 . The nativity of the flesh was the manifestation of human nature: the childbearing of a virgin is the proof of Divine power. The infancy of a babe is shown in the humbleness of its cradle: the greatness of the Most High is proclaimed by the angels’ voices. He whom Herod treacherously endeavors to destroy is like ourselves in our earliest stage: but He whom the Magi delight to worship on their knees is the Lord of all. So too when He came to the baptism of John, His forerunner, lest He should not be known through the veil of flesh which covered His Divinity, the Father’s voice thundering from the sky, said, This is My beloved Son, in whom I am well pleased (Matthew 3:17). And thus Him whom the devil’s craftiness attacks as man, the ministries of angels serve as God. To be hungry and thirsty, to be weary, and to sleep, is clearly human: but to satisfy 5,000 men with five loaves, and to bestow on the woman of Samaria living water, droughts of which can secure the drinker from thirsting any more, to walk upon the surface of the sea with feet that do not sink, and to quell the risings of the waves by rebuking the winds, is, without any doubt, Divine. Just as therefore, to pass over many other instances, it is not part of the same nature to be moved to tears of pity for a dead friend, and when the stone that closed the four-days’ grave was removed, to raise that same friend to life with a voice of command: or, to hang on the cross, and turning day to night, to make all the elements tremble: or, to be pierced with nails, and yet open the gates of paradise to the robber’s faith: so it is not part of the same nature to say, I and the Father are one, and to say, the Father is greater than I. For although in the Lord Jesus Christ God and man is one person, yet the source of the degradation, which is shared by both, is one, and the source of the glory, which is shared by both, is another. For His manhood, which is less than the Father, comes from our side: His Godhead, which is equal to the Father, comes from the Father.
