“I behold a strange and most glorious mystery,” the Church sings with awe, “Heaven, a Cave; the Virgin the Throne of the Cherubim; the Manger a room, in which Christ, the God Whom nothing can contain is laid.” (Irmos of the 9th Ode of the Nativity Canon).

An angel of the Lord (Saint Cyprian says this was Gabriel) came before them and said: “Fear not: for behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Savior, Who is Christ the Lord” (Luke 2:10-11).
