In the Creed we say, “For us men and for our salvation he came down from heaven and by the Holy Spirit was Incarnate of the Virgin Mary and became Man.” This is a very special moment in the reciting of the Creed, and everyone genuflects or bows when these words are spoken.
The Incarnation, God becoming man, the Eternal Word becoming flesh, is the cornerstone of the Christian Faith. God loved us so much that he humbled himself, stooping so low that he became one of his own creatures to reveal himself to us. The prophets saw glimpses of God. The psalmists sang songs about him. The sages spoke of his wisdom. But until God became man in Jesus Christ, we really didn’t know God. The most respected prophet, Moses, only got a glimpse of his backside as he passed by. Indeed, man was always trying to understand God by the trail he left behind as he interacted with mankind.
But in Christ, we see God as he truly is. We can know God. We can love God. We can speak to God as friend to friend because Jesus called us his friends. Therefore, when we refer to the Incarnation in the Creed, we bow in worship to the awesome God who humbled himself to become one of us, for us.
