The solemnity of August 15 celebrates the glorious Assumption of Mary into heaven. It is a feast of her destiny of fullness and blessedness, of the glorification of her immaculate soul and of her virginal body, of her perfect configuration to the Risen Christ; a feast that sets before the eyes of the Church and of all mankind the image and the consoling proof of the fulfillment of their final hope, namely, that this full glorification is the destiny of all those whom Christ has made His brothers, having “flesh and blood in common with them” (Heb. 2:14; cf. Gal. 4:4).

The Solemnity of the Assumption is prolonged in the celebration of the Queenship of the Blessed Virgin Mary, which occurs seven days later. On this occasion we contemplate her who, seated beside the King of ages, shines forth as Queen and intercedes as Mother.
