“Today is made known the mystery that existed before the foundation of the world. The Son of God becomes the Son of Man, so that he may share in what is worse in order to enable me to share in what is better. Adam once was deceived: He longed without success to become God. Now God becomes human to make Adam god. Let creation rejoice, Let nature exult: In awe the archangel approaches the Virgin, conveys her the greeting, our sorrow’s consoling. Glory to you, O God, Who in merciful compassion became a human being” (from Vespers of the 5th Saturday of Lent).
“O man, for your sake was Christ born, and the Son of God came that He might make you to live; He became a babe, He became a child, and He became a man, being (at the same time) God in His Nature, and the Son of God.
He Who was the Lawgiver became a reader, and He took the Book in the synagogue, and read, saying, ‘The Spirit of the Lord is upon Me, therefore He has anointed Me, and has sent Me to preach the Gospel to the poor (Lk 4:18)” (from Paradise of the Holy Fathers).
“The Lord, the Word of God, came down to earth and was incarnate of the Holy Spirit and Mary the Virgin and became man, without change becoming our equal in all things save sin, so that, traversing all that which is ours, He might re-forge and make that first man anew and, through him, all of us who were begotten and came into being from him and are like him who engendered us. Since, because Adam who engendered us had become corruptible and mortal—and, I will add, deaf and blind – and, by reason of his transgression, both naked and insensible of his divine vesture, such being the man of dust, so as well have they all become who were born of him: of dust, corruptible, mortal, deaf, blind, naked and insensible, differing in no way from the irrational animals or, better, become even worse than the beasts as having embraced all the latter’s’ passions and taken them into themselves” (Saint Symeon the New Theologian).
“With the God-man Christ, all that is God’s has become man’s, human, ours, so that each of us individually and all of us assembled together in the Divine-human body of Christ, the Church, might become god-men, having attained ‘to the perfect man, to the measure of the stature of the fullness of Christ’ (Eph 4:12-13). Therefore Christmas, the day of the birth of the God-man, the Lord Jesus Christ, is the greatest and most important day in the history of all the worlds in which man moves and lives” (Saint Nikolai Velimirovich).
