FIRST SUNDAY AFTER CHRISTMAS

Galatians 3:23-25; 4:4-7
John 1:1-18
On Christmas Eve and again on Christmas Day, we heard the familiar account of our Lord’s Nativity, with the angels and shepherds, as told in the Gospel according to Saint Luke. Today, however, on the first Sunday after Christmas, the readings take us deeper into the mystery of the Lord’s Incarnation.
Down through the centuries, the Christian tradition has spoken of three births of Christ. The first birth takes place not in the stable of Bethlehem but in eternity, before the beginning of time. Today’s Gospel reading is taken from the first chapter of Saint John. The Fourth Gospel gives us no Nativity story. Echoing the first line of the Book of Genesis, John begins “in the beginning.” “In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through him, and without him not one thing came into being.”
Here, “the Word” is another name for the Son of God, the Second Person of the Holy Trinity. Before God created the universe, the Son of God already existed. The Nicene Creed proclaims that the Son was “eternally begotten of the Father, God from God, Light from Light, true God from true God, begotten, not made, of one Being with the Father.” And so the doctrine of the Trinity teaches that before the beginning of time, indeed outside time, God the Father begets his coequal and coeternal Son, who shares fully and completely in his Father’s life and being.
It is this Son of God who is called the Word or Logos. This Greek term means something like thought, reason, purpose, plan, or self-expression. When the Father expresses himself, he does so by means of his Word. It is through His Word that God creates the world. So, when we speak of the first of the three births of Christ, we mean this begetting of the eternal Son of God before all ages.
The second birth of Christ is the familiar one of the Christmas story: the birth of the baby Jesus in Bethlehem. John’s Gospel sums it up in one sentence: “And the Word became flesh and lived among us, and we have seen his glory, the glory as of a father's only son, full of grace and truth.”
In other words, the eternal Son of the Father came down from heaven and took flesh in the womb of the Virgin Mary. He assumed our human nature and shared in our human existence. The doctrine of the Incarnation teaches that Jesus Christ is one Person, fully divine and fully human, true God and true man. He is divine on account of his birth from the Father in eternity, and he is human on account of his birth from the Virgin Mary in Bethlehem.
The Incarnation is not so much a concept to be understood as a mystery to be worshipped and adored. The fourth-century church father Gregory of Nazianzus describes the mystery in a series of wonderful paradoxes: “He who has no mother in heaven is now born without father on earth. . . He who is without flesh becomes incarnate; the Word puts on a body; the Invisible is seen; he whom no hand can touch is handled; the Timeless has a beginning; the Son of God becomes Son of Man—Jesus Christ, the same yesterday, today, and forever.”
This second birth of Christ took place at a specific time and place two thousand years ago so that a third birth may take place today: namely, the birth of Christ in our hearts. In this respect, the Blessed Virgin Mary stands as a model for us all, because just as she literally conceived and brought the Christ child into the world, so also, we’re called to let Christ be conceived in our hearts that we may bring him into the world in our own day.
The birth of Christ in our hearts is but the beginning of the process by which we shall be made like him. He is the Son of God by nature; in him we are adopted as sons and daughters of God by grace. As Saint John says in today’s Gospel: “But to all who received him, who believed in his name, he gave power to become children of God …” Saint Paul says something similar in today’s epistle reading: "But when the fullness of time had come, God sent his Son … so that we might receive adoption as children. And … God has sent the Spirit of his Son into our hearts, crying, ‘Abba! Father!’"
The early Church fathers expressed this idea using the wonderful image of a divine exchange. Christ came down from heaven that we might be raised up from the earth. He became what we are that we might become what he is. He shared in our human life that we might share in his divine life. As St. Gregory Nazianzus says in the sermon from which I quoted earlier: “He shares in the poverty of my flesh, that I may share in the riches of his Godhead.”
So, in our celebration of Christmas, we contemplate three births of Christ: the eternal generation of the Son of God before the beginning of time; his coming down from heaven to be born of the Virgin Mary in the stable of Bethlehem; and his birth in our hearts, which is in turn the beginning of our rebirth in his image and likeness.
There’s a sense in which the birth of Christ in Bethlehem remains incomplete until he is born in us. The Christmas Season affords us a wonderful opportunity to invite him in. The nineteenth-century bishop and preacher Phillips Brooks put it well in his great Christmas hymn, “O holy child of Bethlehem, descend to us we pray; cast out our sin and enter in, be born in us today.”
