The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Tuesday, 2014-03-25:
710Again the LORD spoke to Ahaz, 11"Ask a sign of the LORD your God;let it be deep as Sheol or high as heaven." 12But Ahaz said, "I will not ask, and I will not put the LORD to the test." 13And he said, "Hear then, O house of David! Is it too little for you to weary men, that you weary my God also? 14Therefore the Lord himself will give you a sign. Behold, a young woman shall conceive and bear a son, and shall call his name Imman'u-el. 810Take counsel together, but it will come to nought;speak a word, but it will not stand, for God is with us.
6Sacrifice and offering thou dost not desire;but thou hast given me an open ear. Burnt offering and sin offering thou hast not required. 7Then I said, "Lo, I come;in the roll of the book it is written of me;8I delight to do thy will, O my God;thy law is within my heart." 9I have told the glad news of deliverance in the great congregation;lo, I have not restrained my lips, as thou knowest, O LORD. 10I have not hid thy saving help within my heart, I have spoken of thy faithfulness and thy salvation;I have not concealed thy steadfast love and thy faithfulness from the great congregation.
4For it is impossible that the blood of bulls and goats should take away sins.5Consequently, when Christ came into the world, he said, "Sacrifices and offerings thou hast not desired, but a body hast thou prepared for me;6in burnt offerings and sin offerings thou hast taken no pleasure.7Then I said, `Lo, I have come to do thy will, O God, 'as it is written of me in the roll of the book."8When he said above, "Thou hast neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings" (these are offered according to the law),9then he added, "Lo, I have come to do thy will." He abolishes the first in order to establish the second.10And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.
26In the sixth month the angel Gabriel was sent from God to a city of Galilee named Nazareth, 27to a virgin betrothed to a man whose name was Joseph, of the house of David;and the virgin's name was Mary. 28And he came to her and said, "Hail, full of grace, the Lord is with you!"29But she was greatly troubled at the saying, and considered in her mind what sort of greeting this might be. 30And the angel said to her, "Do not be afraid, Mary, for you have found favor with God. 31And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. 32He will be great, and will be called the Son of the Most High;and the Lord God will give to him the throne of his father David, 33and he will reign over the house of Jacob for ever;and of his kingdom there will be no end." 34And Mary said to the angel, "How shall this be, since I have no husband?" 35And the angel said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you;therefore the child to be born will be called holy, the Son of God. 36And behold, your kinswoman Elizabeth in her old age has also conceived a son;and this is the sixth month with her who was called barren. 37For with God nothing will be impossible." 38And Mary said, "Behold, I am the handmaid of the Lord;let it be to me according to your word." And the angel departed from her.
