The ascension of Mary's body into heaven is called the Assumption of Mary by Catholics and the Dormition of the Theotokos by the Greek Orthodox Church. Both churches commemorate the event on August 15; in the Roman Catholic Church, that date is known as the Feast of the Assumption, while in the Eastern Orthodox Church it is known as the Feast of the Dormition (which means "falling asleep"). It should be noted that the Orthodox use of Dormition emphasizes the belief that Mary did bodily die before her Assumption.
