Charles Wesley's wonderful phrase from "Hark, The Herald Angels Sing,"

Veiled in flesh the Godhead see;
Hail the Incarnate Deity

captures the central truth of our Christian faith. Since the appearance of Jesus on this earth two thousand years ago, Christians have believed that the man called Jesus of Nazareth is and was God the Creator; that the eternal Son dwelt in a human body, thus "veiled in flesh the Godhead see." Every other doctrine of Christianity flows out of that great truth. If it be denied, one has denied the heart of Christian faith and has embraced heresy.
