This is by far the best name for the day of joy which we celebrate as the birthday of our Lord. "The Word was made flesh and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father) full of grace and truth" (John 1:14). This is the nativity. That was the incomparable day. The people that had once walked in darkness (Isa. 9:2) were by now sitting in darkness (Matt. 4:16), but God sent the great light to illuminate the darkness of our hearts and to lift men from the abyss of eternal darkness. No human eye could pierce those shadows.
