Ekos 1: An archangel was sent from heaven to say to the Theotokos: Rejoice! And beholding Thee, O Lord, taking bodily form, he was amazed and with his bodiless voice he stood crying to her such things as these:
Rejoice, Thou through whom joy will shine forth:
Rejoice, Thou through whom the curse will cease!
Rejoice, recall of fallen Adam:
Rejoice, redemption of the tears of Eve!
Rejoice, height inaccessible to human thoughts:
Rejoice, depth undiscernible even for the eyes of angels!
Rejoice, for Thou art the throne of the King:
Rejoice, for Thou bearest Him Who beareth all!
Rejoice, star that causest the Sun to appear:
Rejoice, womb of the Divine Incarnation!
Rejoice, Thou through whom creation is renewed:
Rejoice, Thou through whom we worship the Creator!
Rejoice, O Bride Unwedded!
- From the Akathist to the Theotokos (translated: God-bearer)
Today is the Feast of the Dormition of the Theotokos:
The feast of the Dormition or Falling-asleep of the Theotokos is celebrated on the fifteenth of August, preceded by a two-week fast. This feast, which is also sometimes called the Assumption, commemorates the death, resurrection and glorification of Christ's mother. It proclaims that Mary has been "assumed" by God into the heavenly kingdom of Christ in the fullness of her spiritual and bodily existence.
As with the nativity of the Virgin and the feast of her entrance to the temple, there are no biblical or historical sources for this feast. The Tradition of the Church is that Mary died as all people die, not "voluntarily" as her Son, but by the necessity of her mortal human nature which is indivisibly bound up with the corruption of this world.
The Orthodox Church teaches that Mary is without personal sins. In the Gospel of the feast, however, in the liturgical services and in the Dormition icon, the Church proclaims as well that Mary truly needed to be saved by Christ as all human persons are saved from the trials, sufferings and death of this world; and that having truly died, she was raised up by her Son as the Mother of Life and participates already in the eternal life of paradise which is prepared and promised to all who "hear the word of God and keep it." (Luke 11:27-28)
