Mary in Christian Tradition
The Assumption of Mary (August 15)
As the Feast of the Immaculate Conception proclaims the grace of Christ in Mary before he was born, so the Feast of the Assumption points to the fulfillment of that grace, when Mary was taken, body and soul, into heaven to share in the glory of her Son's Resurrection. The Church proclaimed this dogma in 1950:
Like the mystery of her Immaculate Conception, the Assumption of Mary is significant for all humanity, since she anticipates our resurrection with Christ in glory. She was taken up to heaven as "the beginning and the pattern of the Church in its perfection, and a sign of hope and comfort for your people on their pilgrim way." (Preface of the Assumption)
Readings for the feast
The readings for the feast dwell on the promise of heaven's glory. The Book of Revelations presents the sign of "the woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars." (Book of Revelation 11, 19) The reading from I Corinthians promises that all will be raised, who are members of Christ. (1 Corinthians 15, 20-26) The gospel reading is Mary's Magnificat, her song of praise that "God has raised up the lowly to high places." (Luke 1, 39-56)
This feast has its roots in the early Jerusalem church and in the churches of the East.
