Annunciation

Luke 1: 26-38  [26] And in the sixth month, the angel Gabriel was sent from God into a city of Galilee, called Nazareth, [27] To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin' s name was Mary. [28] And the angel being come in, said unto her: Hail, full of grace, the Lord is with thee: blessed art thou among women. [29] Who having heard, was troubled at his saying, and thought with herself what manner of salutation this should be. [30] And the angel said to her: Fear not, Mary, for thou hast found grace with God.

Visitation

Luke 1: 41-45 [41] And it came to pass, that when Elizabeth heard the salutation of Mary, the infant leaped in her womb. And Elizabeth was filled with the Holy Ghost: [42] And she cried out with a loud voice, and said: Blessed art thou among women, and blessed is the fruit of thy womb. [43] And whence is this to me, that the mother of my Lord should come to me? [44] For behold as soon as the voice of thy salutation sounded in my ears, the infant in my womb leaped for joy. [45] And blessed art thou that hast believed, because those things shall be accomplished that were spoken to thee by the Lord.

Presentation in Temple

Luke 2: 25-30

[25] And behold there was a man in Jerusalem named Simeon, and this man was just and devout, waiting for the consolation of Israel; and the Holy Ghost was in him.

[26] And he had received an answer from the Holy Ghost, that he should not see death, before he had seen the Christ of the Lord. [27] And he came by the Spirit into the temple. And when his parents brought in the child Jesus, to do for him according to the custom of the law, [28] He also took him into his arms, and blessed God, and said: [29] Now thou dost dismiss thy servant, O Lord, according to thy word in peace; [30] Because my eyes have seen thy salvation.
