death shortly before her Assumption. Dormition is part of accepted Eastern Catholic theology, but not part of Roman Catholic doctrine. Assumption: Mary was taken bodily into heaven either at, or before, her death. The acceptance of these Marian doctrines by Roman Catholics and other Christians can be summarized as follows: The title "Mother of God" () for Mary was confirmed by the First Council of Ephesus, held at the Church of Mary in 431. The Council decreed that Mary is the Mother of God because her son Jesus is one person who is both God and man, divine and human.
