The Assumption of Mary is one of the four Marian dogmas of the Catholic Church. The dogma declares a doctrinal belief in the bodily taking up of the Virgin Mary to heaven at the end of her life on earth. Pope Pius XII defined the dogma of the Assumption of the Virgin Mary in 1950 in his apostolic constitution Munificentissimus Deus as follows: We proclaim and define it to be a dogma revealed by God that the immaculate Mother of God, Mary ever virgin, when the course of her earthly life was finished, was taken up body and soul into the glory of heaven. The declaration was built upon the dogma of the Immaculate Conception of Mary in 1854, which declared that Mary was conceived free from original sin, and both have their foundation in the concept of Mary as the Mother of God. It leaves open the question of whether Mary died or whether she was raised to eternal life without bodily death. Source: Duckduckgo API
