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 the perennial 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.”
His Apostolic Constitution “Munificentissimus Deus” (Most Bountiful God), which defined the dogma,
contained the Pontiff's accounts of many longstanding traditions by which the Church has celebrated the Assumption throughout its history.
The constitution also cited testimonies from the early Church fathers on the subject, and described the history of theological reflection on many Biblical passages which are seen as indicating that Mary was assumed into heaven following her death.
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 12th chapter of 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.
Eastern Christians have also traditionally held Mary's assumption into heaven as an essential component of their faith. Pius XII cited several early Byzantine liturgical texts, as well as the eighth-century Arab Christian theologian St. John of Damascus, in his own authoritative definition of her assumption.
“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. Eastern Catholic celebration of the Dormition is preceded by a two-week period of fasting which is similar to Lent. Pius XII, in “Munificentissimus Deus,” mentioned this same fasting period as belonging to the traditional patrimony of Western Christians as well.
The feast of the Assumption is always a Holy Day of Obligation for both Roman and Eastern-rite Catholics, on which they are obliged to attend Mass or Divine Liturgy, unless the feast day falls on a Sunday.
The Assumption in the Catechism of the Catholic Church
966 "Finally the Immaculate Virgin, preserved free from all stain of original sin, when the course of her earthly life was finished, was taken up body and soul into heavenly glory, and exalted by the Lord as Queen over all things, so that she might be the more fully conformed to her Son, the Lord of lords and conqueror of sin and death." The Assumption of the Blessed Virgin is a singular participation in her Son's Resurrection and an anticipation of the resurrection of other Christians: In giving birth you kept your virginity; in your Dormition you did not leave the world, O Mother of God, but were joined to the source of Life. You conceived the living God and, by your prayers, will deliver our souls from death.
2853 Victory over the "prince of this world" was won once for all at the Hour when Jesus freely gave himself up to death to give us his life. This is the judgment of this world, and the prince of this world is "cast out." "He pursued the woman" but had no hold on her: the new Eve, "full of grace" of the Holy Spirit, is preserved from sin and the corruption of death (the Immaculate Conception and the Assumption of the Most Holy Mother of God, Mary, ever virgin). "Then the dragon was angry with the woman, and went off to make war on the rest of her offspring." Therefore the Spirit and the Church pray: "Come, Lord Jesus," since his coming will deliver us from the Evil One.
2177 The Sunday celebration of the Lord's Day and his Eucharist is at the heart of the Church's life. "Sunday is the day on which the paschal mystery is celebrated in light of the apostolic tradition and is to be observed as the foremost holy day of obligation in the universal Church."
"Also to be observed are the day of the Nativity of Our Lord Jesus Christ, the Epiphany, the Ascension of Christ, the feast of the Body and Blood of Christi, the feast of Mary the Mother of God, her Immaculate Conception, her Assumption, the feast of Saint Joseph, the feast of the Apostles Saints Peter and Paul, and the feast of All Saints."
