The Assumption of Mary into Heaven is, according to the beliefs of the Catholic Church, Eastern and Oriental Orthodoxy, the bodily taking up of the Virgin Mary into Heaven at the end of her earthly life.
The Catholic Church teaches as dogma that the Virgin Mary “having completed the course of her earthly life, was assumed body and soul into heavenly glory”. This doctrine was dogmatically defined by Pope Pius XII on 1 November 1950, in the apostolic constitution Munificentissimus Deus (in English: The Most Bountiful God)by exercising papal infallibility. While the Catholic Church and Eastern Orthodox Church believe in the Dormition of the Mother of God (the Falling Asleep of the Mother of God), whether Mary had a physical death has not been dogmatically defined. In Munificentissimus Deus (item 39) Pope Pius XII pointed to the Book of Genesis 3:15 as scriptural support for the dogma in terms of Mary’s victory over sin and death through her intimate association with “the new Adam” (Christ) as also reflected in 1 Corinthians 15:54: “then shall come to pass the saying that is written, Death is swallowed up in victory”.
In the churches that observe it, the Assumption is a major feast day, commonly celebrated on 15 August. In the Roman Catholic Church, it is a Solemnity and a Holy Day of Obligation.
