Today, August 15, is the Feast of the Assumption, the principal feast of the Blessed Virgin. According to the Catholic Encyclopedia, the feast celebrates both the “happy departure of Mary from this life” and the “assumption of her body into heaven.” That she “was taken up body and soul into heavenly glory, when her earthly life was over, and exalted by the Lord as Queen over all things” is a principle of Catholic dogma.
It is one of six Holy Days of Obligation. Catholics are obliged to attend mass today.
