Immaculate Conception

Nine months before the Feast of the Nativity of the Blessed Virgin Mary (8 September), the Church celebrates the Solemnity of her Immaculate Conception. The Feast was approved in 1476 by Pope Sixtus IV. It was extended to the universal Church by Pope Clement XI in 1708.
Acknowledging the belief held for centuries by the Fathers and Doctors of the Church, of councils and his predecessors, Pope Pius IX solemnly proclaimed the Dogma of the Immaculate Conception in 1854: “We declare, pronounce, and define that the doctrine which holds that the most Blessed Virgin Mary, in the first instance of her conception, by a singular grace and privilege granted by Almighty God, in view of the merits of Jesus Christ, the Savior of the human race, was preserved free from all stain of original sin” (Ineffabilis Deus, 1854)

The angel Gabriel was sent from God to a town of Galilee called Nazareth, to a virgin betrothed to a man named Joseph, of the house of David, and the virgin’s name was Mary. And coming to her, he said, “Hail, full of grace! The Lord is with you.” But she was greatly troubled at what was said and pondered what sort of greeting this might be. Then the angel said to her, “Do not be afraid, Mary, for you have found favor with God. Behold, you will conceive in your womb and bear a son, and you shall name him Jesus. He will be great and will be called Son of the Most High, and the Lord God will give him the throne of David his father, and he will rule over the house of Jacob forever, and of his Kingdom there will be no end.” But Mary said to the angel, “How can this be, since I have no relations with a man?” And the angel said to her in reply, “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. And behold, Elizabeth, your relative, has also conceived a son in her old age, and this is the sixth month for her who was called barren; for nothing will be impossible for God.” Mary said, “Behold, I am the handmaid of the Lord. May it be done to me according to your word.” Then the angel departed from her (Lk. 1:26-38).
