Pope Benedict XVI on the Incarnation of Christ

With the Christmas liturgy the Church ushers us into the great Mystery of the Incarnation. Christmas, in fact, is not merely an anniversary of Jesus’ Birth; it is also this, but it is more, it is celebrating a mystery that has marked and continues to mark human history. God himself came to dwell among us (cf. Jn 1:14), he made himself one of us. It is a mystery that concerns our faith and our life; a mystery that we actually experience in the liturgical celebrations, and, in particular, in Holy Mass.
