The Assumption Of The Blessed Virgin Mary

Mary was cared for by St. John for twelve years after our Lord's Resurrection. Her life was spent in helping the Apostles and in praying for the conversion of the world. On the third day after Mary's death, when the Apostles gathered around her tomb, they found it empty. The sacred body had been carried up to the celestial paradise. Jesus Himself came to conduct her thither; the whole court of heaven came to welcome with songs of triumph the Mother of the Divine Word.
(The Roman Missal, 1962)

Collect for today, August 15:

Almighty everlasting God, who hast taken body and soul into heaven the Immaculate Virgin Mary, Mother of Thy Son: grant, we beseech Thee, that by steadfastly keeping heaven as our goal we may be counted worthy to join her in glory. Through the same Christ, our Lord, who lives and reigns with Thee and Thy Holy Ghost forever and ever. Amen
