As we approach the feast of the Lord’s Nativity, our Church “celebrates the past,” by commemorating the forefathers, the spiritual and physical ancestors of Christ, the holy prophets and patriarchs of the Old Testament. To some of them, the Scripture specifically attributes particular prophetic texts which point to Christ. Others, simply by their place in the Genealogy of Christ, point to the reality of His human nature and His connection to the people of Israel: “Son of David, son of Abraham.”
Finally, our celebration of the Nativity, built around the imagery of the infancy narratives in Matthew and Luke, takes us back to the time of His coming in the flesh, the event to which the Old Testament pointed. As we sing on the Sunday before Christmas, “O Mary, unwedded Mother, in your virginal womb you bore Christ, whom the prophets had once foretold in contemplation. By His Nativity He now makes the Fathers exult with joy!” (canon, ode 6).
Celebrating the Present: Theosis
While the secular celebration of Christmas, with its crèches and carols, is often content to focus only on the past, the tradition of our Church is more interested in the present: the meaning of Christ’s coming for our life today. Our Byzantine hymns continually connect Gospel events from the past to the present by affirming that “Today the Virgin is on her way to the cave…” – “Now the prophecy is about to be fulfilled…” and “Christ is born…” Christ’s nativity – and all the mysteries of the Church year – are not are not a matter of looking back in time; we celebrate them because they are affecting us now.The purpose of Christ’s coming in the flesh – His incarnation – is to change our life. The early Fathers expressed that purpose in this way: “Christ became human so that man might become divine.” As we sing at every Divine Liturgy, the “only-begotten Son and Word of God” took flesh, became incarnate, assumed our human nature. He took up our nature, becoming like us in all things, except sin, in order to give us a share in His divine nature. The fruit of His incarnation is our deification.
Theosis, the Greek term for deification, means that, because God has become one of us, we can become like Him. He is the only truly Holy One, yet we can become holy by sharing in His life. Because of the incarnation, the impossible has become possible: we can become perfect as our heavenly Father is perfect.
Our celebration of Christ’s Nativity proclaims Theosis as the very purpose of the incarnation. During the week leading up to Christmas, we sing this troparion which portrays the Incarnation as fulfilling the original purpose of creation: “Bethlehem, make ready, for Eden has been opened for all… Christ is coming forth to bring back to life the likeness that had been lost in the beginning.” This reflects the Genesis story of creation, in which “God said, ‘Let Us make man in Our image, according to Our likeness’… so God created man in His own image; in the image of God He created him; male and female He created them” (Genesis 1:26, 27). In the teaching of the Church Fathers, this “image” of God in us means the spiritual side of our nature, which distinguishes us from the lower orders of creation. They explained the “likeness” to mean the ability to act in a holy, godlike manner. With the fall, the Fathers teach, we lost that likeness. We retained the image of God in us, but it was scarred, unable to function as God intended.
With the Incarnation, this likeness was restored to mankind in the person of the Lord Jesus. He was a “new Adam,” the man that God intended. Christ communicated a share in this restored likeness to others after His death and resurrection. By being united to Him in baptism, we could become by God’s grace “partakers of the divine nature” (2 Peter 1:4). We no longer relate to God simple as creature to Creator, but as sharers in His own life.
Christ’s incarnation, then, is an invitation to believers to be what we have become, to live in accordance with this share we have in the divine nature. We can live in a close fellowship with God: the intimacy described in Genesis as “walking with God” in the Garden. When we struggle to conform to the image of Christ as depicted in the Gospels, our potential to reflect the likeness to God gradually becomes evident. This is the path to sainthood, made possible by the incarnation.
Celebrating the Future: Transfiguration
The word “incarnation” literally means “becoming flesh.” The Son of God took on the fullness of our human nature, including the body, and transformed it. He rose from the dead and ascended into heaven in the body. The result of the Incarnation is that there is a human body in heaven, seated at the Father’s right! The incarnation is unto the ages.In several of his epistles, St Paul sets forth the Gospel teaching that the risen Christ is “the firstborn among many brethren” {Romans 8:29), “the firstborn from the dead” (Colossians 1:18). As He is, so we are meant to be.
“But someone will say, ‘How are the dead raised up? And with what body do they come?’” (1 Corinthians 15:35). After all, the dissolution of the dead body as it returns to the earth is visible to all. St Paul explains at length what the resurrection entails: “When you sow, you do not sow that body that shall be, but mere grain—perhaps wheat or some other grain. But God gives it a body as He pleases, and to each seed its own body… So also is the resurrection of the dead. The body is sown in corruption, it is raised in incorruption. It is sown in dishonor, it is raised in glory. It is sown in weakness, it is raised in power. It is sown a natural body, it is raised a spiritual body. There is a natural body, and there is a spiritual body … And as we have borne the image of the man of dust, we shall also bear the image of the heavenly Man” (1 Corinthians 15:37-49). This “image of the heavenly Man” was revealed to us in the transfiguration of Christ: the human body imbued with the presence of the divine life.
When we celebrate the Incarnation, then, we are celebrating the future of the body which the Son of God assumed – and that is our future as well. As Christ’s body is glorified now, so our bodies – our “spiritual bodies,” to use St Paul’s phrase – are meant to be glorified in the age to come. Because of the incarnation, our life in Christ lived in our earthly bodies is destined to be climaxed by an eternal life lived in bodies raised in glory and power – in the image of the heavenly Man.
Hymns on the Sunday before Christmas
“He has shared my poverty, becoming man so that I might become God-like and share in His riches” (sticheron at vespers).“A strange mystery, wondrous, which causes amazement: the Lord of glory has come down upon earth! He has appeared in a cave, bearing our nature, in order to raise up Adam and to free from her pains the ancient mother of all the living” (canon, ode 9).
