The Son of God, the Incarnation
Before His personal birth of the Virgin Mary as the man Jesus, the divine Son and Word of God was in the world by His presence and action in creation, particularly in man. He was present and active; also in the theophanies to the Old Testament saints; and in the words of the law and the prophets, both oral and scriptural. Because of his perfect love, God sent forth his Son into the world. God knew in the very act of creation that to have a world at all would require the incarnation of his Son in human flesh.
