This Sunday we celebrate the joy of Christmas in the incarnation of Jesus, the divine Son of God, who became a human being for our salvation. Christian conviction about the incarnation generates questions from skeptics and believers alike. Was it really necessary for God to become a man? What would motivate God to come in this way? How can I be sure about the incarnation? What does the incarnation mean in my life and for our world today?
Athanasius again will help us. His understanding of the incarnation was forged during the explosive 4th century AD. Much of his world found the incarnation offensive or absurd. Some who claimed to follow Christ denied his full divinity or the reality of his humanity. In the climax of his work, Athanasius claims that the incarnation is not only possible but absolutely necessary. Since all human beings had gone astray, only a divine Savior could rescue them. Since death had come into humanity, only a divine Savior could bring them new life. For Athanasius, the ultimate evidence of Christmas is the transformed lives of all who believe.
