Today, Catholics and many other Christians celebrate the feast of the Assumption of the Blessed Virgin Mary. This significant feast day recalls the spiritual and physical departure of the mother of Jesus Christ from the earth, when both her soul and her resurrected body were taken into the presence of God.
Venerable Pope Pius XII confirmed this belief about the Virgin Mary as a teaching of the Church when he defined it formally as a dogma of Catholic faith in 1950, invoking papal infallibility to proclaim, “that the Immaculate Mother of God, the ever-Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory.”
Although the bodily assumption of Mary is not explicitly recorded in Scripture, Catholic tradition identifies her with the “woman clothed with the sun” who is described in the Book of Revelation.
The passage calls that woman's appearance “a great sign” which “appeared in heaven,” indicating that she is the mother of the Jewish Messiah and has “the moon under her feet, and on her head a crown of twelve stars.” Accordingly, Catholic iconography of the Western tradition often depicts the Virgin Mary's assumption into heaven in this manner.
“It was fitting,” St. John of Damascus wrote in a sermon on the Assumption, “that she, who had kept her virginity intact in childbirth, should keep her own body free from all corruption even after death,” and “that she, who had carried the creator as a child at her breast, should dwell in the divine tabernacles.”
In Eastern Christian tradition, the same feast is celebrated on the same calendar date, although typically known as the Dormition (falling asleep) of Mary.
