What is the Assumption of Mary?

The Assumption of Mary is the Catholic dogma that at the end of her earthly life, the Blessed Virgin Mary, body and soul, was taken up into the glory of heaven. Defined infallibly by Pope Pius XII in 1950, it is celebrated as a holy day of obligation on August 15 and reflects Mary's unique sharing in her Son's victory over sin and death.

The Assumption of Mary teaches that the Mother of God, having completed the course of her earthly life, was assumed body and soul into heavenly glory (CCC 966). Unlike Christ's Ascension, which He accomplished by His own divine power, Mary's Assumption was a gift given to her by God, a singular participation in her Son's resurrection and a preview of the resurrection that awaits all the redeemed (CCC 966, 974).

This teaching was solemnly defined as dogma by Pope Pius XII in the 1950 apostolic constitution Munificentissimus Deus, though it had been believed and celebrated by the faithful for many centuries before that formal definition. The Church does not teach whether Mary died before being assumed, leaving that question open, though the ancient tradition of the East, called the Dormition, holds that she fell asleep in death before her Son raised her body to glory.

Why the Church Believes This

The Assumption flows from Mary's unique role as the Immaculate Conception and the Mother of God. Because she was preserved free from all stain of sin from the moment of her conception, she was also preserved from the corruption of the grave that is the wages of sin (CCC 966, 491). Her bodily glorification is the fitting completion of a life wholly conformed to Christ.

Scripture does not narrate the Assumption directly, but the Church sees it prefigured and confirmed in the whole of revelation. The angel's greeting to Mary as 'full of grace' (Luke 1:28) and her own prophecy that 'all generations shall call me blessed' (Luke 1:48) point to a woman set apart for extraordinary glory. Revelation 12:1 depicts 'a woman clothed with the sun, and the moon under her feet, and on her head a crown of twelve stars,' an image the Church has long applied to Mary in her heavenly exaltation. Saint Paul's teaching that Christ is 'the firstfruits of them that sleep' and that in Him 'all shall be made alive' (1 Corinthians 15:20-22) finds its first and fullest realization in Mary.

What the Assumption Means for Us

The Assumption is not merely an honor paid to Mary; it is a sign of hope for every Christian. As Vatican II and the Catechism teach, Mary's glorification in body and soul is the image and beginning of the Church's own destiny, since all the faithful hope one day to share in the resurrection of the body (CCC 966, 974). She stands as the model disciple who followed Christ perfectly and now reigns with Him, interceding for us as Mother and Queen.

The Church celebrates the Solemnity of the Assumption on August 15, one of the principal Marian feasts and, in most places, a holy day of obligation, inviting the faithful to contemplate both Mary's glory and their own hope of everlasting life with God.
