The official name of our parish is St. Mary of the Assumption Parish and so, the main window in the choir loft over the street entrance to our building is The Assumption of Mary.
--------------------------------------
The feast of Mary’s Assumption is a preview of what our lives will be. At the end of her earthly life, Mary was assumed, or taken up, into heaven body and soul. She did not have to wait for the end of the world, as we do. God granted her this special privilege because of her sinlessness and her fullness of grace.
The Church has always believed in Mary’s assumption into heaven. But on November 1, 1950, Pope Pius XII focused the attention of the whole world on the Assumption of Mary as a dogma and mystery of our faith. This mystery shows us that God wants every human person, body and soul, to be in glory forever, just as Mary is now.
