Hebrews 1:1-12
John 1:1-14
Yesterday, on Christmas Eve, we heard the familiar account of the Lord’s Nativity, complete with the angels and shepherds, as told in the Gospel according to Saint Luke. This morning, however, the appointed readings for Christmas Day take us deeper into the great mystery of the Lord’s Incarnation.
Down through the centuries, the Christian tradition has spoken of not just one but three births of Christ. The first birth takes place in eternity, before the beginning of time. Today’s Gospel is taken from what’s known as the Prologue to Saint John. The Fourth Gospel, the Gospel of John, gives us no Nativity story as such. Rather, echoing the first verse of the first chapter 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” denotes the Son of God, the Second Person of the Holy Trinity. In John’s Greek, "Word" or Logos means something like thought, reason, purpose, plan, or self-communication. And it’s by speaking this Word that God creates the world. Our reading this morning from the Letter to the Hebrews similarly describes the Son of God as the one “whom [God] appointed heir of all things, through whom he also created the worlds. He is the reflection of God's glory and the exact imprint of God's very being, and he sustains all things by his powerful word.”
So, even before the universe’s creation, God the Son already exists. The Nicene Creed, which we recite every Sunday and major holy day, affirms that the Son is “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.” In other words, even before the beginning of time, God the Father begets the God the Son, who shares co‑equally and co-eternally with the Father in the Godhead’s own life and being.
So, when we speak of the first of the Christ’s three births, we mean this eternal begetting or generation of the Son of God from his Father before all ages, outside of time and space.
The second birth of Christ is the more familiar one that we encounter at Christmas time: the birth of the infant Jesus in Bethlehem. John’s Gospel sums that whole story up in just 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 God came down from heaven and took flesh in the womb of the Virgin Mary to assume our human nature and to share fully 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's divine on account of his heavenly birth from the Father in eternity; and he’s human on account of his earthly birth from the Virgin Mary in Bethlehem.
Thus expressed, the Incarnation of the Son of God is not so much an proposition to be understood, or a puzzle to be solved, as a mystery to be worshipped and adored. The fourth century church father Gregory of Nazianzus describes this mystery in one of his sermons by 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, Bethlehem in Judea 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. Just as she literally conceived and brought the Christ child into the world, so we’re all called to let Christ be conceived in our hearts so that we may bear him into the world in our own day.
This birth of Christ in our hearts begins the lifelong process by which we become like him. As he’s the Son of God by nature, so in him we become sons and daughters of God by adoption and grace. As John also says in today’s Gospel: “But to all who received him, who believed in his name, he gave power to become children of God …”
The early Church fathers expressed this idea by the image of a wonderful divine exchange. Christ came down to earth that he might raise us up to heaven. 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. Or again, as St. Gregory Nazianzus puts it in the sermon from which I’ve already quoted: “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. First, the eternal begetting of the Son from the Father before the beginning of time. Second, his coming down from heaven to be born of the Virgin Mary in Bethlehem during the reign of Caesar Augustus. And third, his birth in our hearts, here and now, which in turn marks 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’s born in each of us. The Christmas Season affords us a wonderful opportunity to invite him in. As the nineteenth century bishop and preacher Phillips Brooks put it 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.”
