First of all, let us see what the Incarnation means. In the Gospel of Saint Luke we heard the words of the angel to Mary: “The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy, the Son of God” (Lk 1:35). In Mary, the Son of God is made man, fulfilling in this way the prophecy of Isaiah: “Behold, a young woman shall conceive and bear a son, and shall call his name Immanuel, which means ”˜God-with-us’” (Is 7:14). Jesus, the Word made flesh, is truly God-with-us, who has come to live among us and to share our human condition. The Apostle Saint John expresses it in the following way: “And the Word became flesh and dwelt among us” (Jn 1:14). The expression, “became flesh” points to our human reality in most concrete and tangible way. In Christ, God has truly come into the world, he has entered into our history, he has set his dwelling among us, thus fulfilling the deepest desire of human beings that the world may truly become a home worthy of humanity. On the other hand, when God is put aside, the world becomes an inhospitable place for man, and frustrates creation’s true vocation to be a space for the covenant, for the “Yes” to the love between God and humanity who responds to him. Mary did so as the first fruit of believers with her unreserved “Yes” to the Lord.
