The Dormition and Assumption of the Theotokos

Today the Apostolic Churches, both East and West (who use the contemporary calendar), celebrate the falling-asleep of the Mother of God, "our most holy, most pure, most glorious and blessed Lady, the Theotokos and Ever-Virgin Mary", followed by her assumption, body and soul, into Heaven, the first fruits of the general resurrection.

"And a great sign appeared in heaven, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars." (Revelation 12:1)

From St. Gregory Palamas: "A Homily on the Dormition"
