VATICAN CITY, DEC. 25, 2005 (Zenit.org).- Here is a translation of the homily Benedict XVI delivered at Midnight Mass on Christmas Eve, held in St. Peter's Basilica.
"The Lord said to me: You are my son; this day I have begotten you." With these words of the second Psalm, the Church begins the Vigil Mass of Christmas, at which we celebrate the birth of Jesus Christ our Redeemer in a stable in Bethlehem. This psalm was once a part of the coronation rite of the kings of Judah. The people of Israel, in virtue of its election, considered itself in a special way a son of God, adopted by God. Just as the king was the personification of the people, his enthronement was experienced as a solemn act of adoption by God, whereby the king was in some way taken up into the very mystery of God. [On] Bethlehem Night, these words, which were really more an expression of hope than a present reality, took on new and unexpected meaning. The Child lying in the manger is truly God's Son. God is not eternal solitude but rather a circle of love and mutual self-giving. He is Father, Son and Holy Spirit.
But there is more: In Jesus Christ, the Son of God, God himself became man. To him the Father says: "You are my son." God's everlasting "today" has come down into the fleeting today of the world and lifted our momentary today into God's eternal today. God is so great that he can become small. God is so powerful that he can make himself vulnerable and come to us as a defenseless child, so that we can love him. God is so good that he can give up his divine splendor and come down to a stable, so that we might find him, so that his goodness might touch us, give itself to us and continue to work through us. This is Christmas: "You are my son, this day I have begotten you."
God has become one of us, so that we can be with him and become like him. As a sign, he chose the Child lying in the manger: This is how God is. This is how we come to know him. And on every child shines something of the splendor of that "today," of that closeness of God which we ought to love and to which we must yield -- it shines on every child, even on those still unborn.
