The truth of Christ's Incarnation

Believe, too, that the Only-Begotten Son of God came down from heaven to earth for our sins, taking on the passable human nature of ours, and being born of the Holy Virgin and the Holy Spirit, His incarnation taking place, not in appearance or fantasy, but in truth.  He did not pass through the Virgin as a channel, but was truly made flesh from her.  St. Cyril of Jerusalem
