The Feast of the Annunciation is one of the earliest Christian feasts, and was already being celebrated in the fourth century. There is a painting of the Annunciation in the catacomb of Priscilla in Rome dating from the second century. The Council of Toledo in 656 mentions the Feast, and the Council in Trullo in 692 says that the Annunciation was celebrated during Great Lent.
The Greek and Slavonic names for the Feast may be translated as “good tidings.” This, of course, refers to the Incarnation of the Son of God and the salvation He brings. The background of the Annunciation is found in the Gospel of Saint Luke (1:26-38). The troparion describes this as the “beginning of our salvation, and the revelation of the eternal mystery,” for on this day the Son of God became the Son of Man.
There are two main components to the Annunciation: the message itself, and the response of the Virgin. The message fulfills God’s promise to send a Redeemer (Genesis 3:15): “I will put enmity between you and the woman, between your seed and her seed; he shall crush your head, and you shall lie in wait for his heel.” The Fathers of the Church understand “her seed” to refer to Christ. The prophets hinted at His coming, which they saw dimly, but the Archangel Gabriel now proclaims that the promise is about to be fulfilled.
