According to Roman Catholic doctrine and the traditions of the Catholic Church, the Blessed Virgin Mary (Mary, the mother of Jesus) "having completed the course of her earthly life, was assumed body and soul into heavenly glory." This means that Mary was transported into Heaven with her body and soul united. The feast day recognizing Mary's passage into Heaven is celebrated as The Feast of the Assumption of the Blessed Virgin Mary by Roman Catholics. This doctrine was dogmatically and infallibly defined by Pope Pius XII on 1 November 1950 in his Apostolic Constitution Munificentissimus Deus.
