For our final post of Fathers and the Feast of the Nativity, we look at a sermon of Basil of Caesarea. In about another week (January 1), we will celebrate his feastday.
God is on earth, God is among us, not now as lawgiver – there is no fire, trumpet blast, smoke-wreathed mountain, dense cloud, or storm to terrify whoever hears him – but as one gently and kindly conversing in a human body with his fellow men and women. God is in the flesh. Now he is not acting intermittently as he did through the prophets. He is bringing back to himself the whole human race, which he has taken possession of and united to himself. By his flesh he has made the human race his own kin.
But how can glory come to all through only one? How can the Godhead be in the flesh? In the same way as fire can be in iron: not by moving from place to place but by the one imparting to the other its own properties. Fire does not speed toward iron, but without itself undergoing any change it causes the iron to share in its own natural attributes. The fire is not diminished and yet it completely fills whatever shares in its nature. So is it also with God the Word. He did not relinquish his own nature and yet he dwelt among us. He did not undergo any change and yet the Word became flesh. Earth received him from heaven, yet heaven was not deserted by him who holds the universe in being.
Let us strive to comprehend the mystery. The reason God is in the flesh is to kill the death that lurks there. As diseases are cured by medicines and assimilated by the body, and as darkness in a house is dispelled by the coming of light, so death, which held sway over human nature, is done away with by the coming of God. And as ice formed on water covers its surface as long as night and darkness last but melts under the warmth of the sun, so death reigned until the coming of Christ; but when the grace of God our Saviour appeared and the Sun of Justice rose, death was swallowed up in victory, unable to bear the presence of true life. How great is God’s goodness, how deep his love for us!
Let us join the shepherds in giving glory to God, let us dance with the angels and sing: Today a saviour has been born to us. He is Christ the Lord. The Lord is God and he has appeared to us, not as God, which would have been terrifying for our weakness, but as a slave so as to free those who live in slavery. Who could be so lacking in sensibility and so ungrateful as not to join all here present in our gladness, exultation, and radiant joy? This feast belongs to the whole of creation. Let everyone contribute and be grateful. Let our voices too ring out in songs of jubilation.
