I think the main point to consider during the Christmas season is the Incarnation, and I would like to share with you some words from Fr. R. Rolheiser.
"...of critical importance, is the question of the ongoing nature of the Incarnation. The Incarnation is not a thirty-three year experiment by God in history, a one-shot, physical incursion into our lives. The Incarnation began with Jesus and it has never stopped. The ascension of Jesus did not end, nor fundamentally change, the Incarnation. God's physical body is still among us. God is still present, as physical and as real today, as God was in the historical Jesus. God still has skin, human skin, and physically walks on this earth just as Jesus did. In a certain manner of speaking, it is true to say that, at the ascension, the physical body of Jesus left this earth, but the body of Christ did not.
God's Incarnational Presence among us continues as before. ... We are the Body of Christ. This is not an exaggeration, nor a metaphor. To say that the body of believers is the Body of Christ is not to say something that Scripture does not. Scripture, and Paul in particular, never tells us that the body of believers replaces Christ's body, nor that it represents Christs body, nor even that it is Christ's mystical body. It says simply" "We are Christ's body."
Almighty God, You have poured upon us the new Light of Your Incarnate Word: Grant that this Light, enkindled in our hearts, may shine forth in our lives; through Jesus Christ our Lord, Who lives and reigns with You, in the unity of the Holy Spirit, one God, now and for ever. Amen.
