Assumption of Mary
Great Feast of the Eastern Orthodox, Oriental Orthodox, and Eastern Catholic Churches
The Assumption of Mary is one of the four dogmas the Catholic Church has about Mary. Pope Pius XII defined it on 1 November 1950 in his apostolic constitution Munificentissimus Deus. It says that Mary went straight into heaven.
The Assumption of Mary is celebrated in the Catholic calendar on August 15, a holy day of obligation, recognized in some countries as a non-working day. This solemnity is considered the most important Marian celebration of the liturgical year.
The Assumption of Mary is included in the Glorious Mysteries of the Saint Rosary.
