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 St 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.

The Archangel Gabriel was sent by God to Nazareth in Galilee. There he spoke to the undefiled Virgin who was betrothed to St Joseph: "Hail, thou who art highly favoured, the Lord is with thee: blessed art thou among women. And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name Jesus. He shall be great, and shall be called the Son of the Most High: and the Lord God shall give unto him the throne of his father David: And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end."

The Virgin did not immediately accept the Angel's message. In her humility, she did not think she was deserving of such words, but was actually troubled by them. The fact that she asked for an explanation reveals her sobriety and prudence. She did not disbelieve the words of the angel, but could not understand how they would be fulfilled, for they spoke of something which was beyond nature.

Then said Mary unto the angel, How shall this be, seeing I know not a man?" (Luke 1:34).

"And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Most High shall overshadow thee: therefore also that which shall be born of thee shall be called the Son of God. And, behold, thy cousin Elisabeth hath also conceived a son in her old age: and this is the sixth month with her, who was called barren. For with God nothing shall be impossible.' And Mary said, 'Behold the handmaid of the Lord; be it unto me according to thy word.' And the angel departed from her" (Luke 1: 35-38)."
