The day after the feast of the Annunciation is also dedicated to the Archangel Gabriel.
HAIL, initiate of an ineffable counsel,
Hail, faith in things that demand silence.
Hail, for ineffably you gave birth to the Light,
Hail, for to none you revealed the mystery.
Akathist Hymn to the Mother of God.
SHE did not minister, as the Apostles did. Rather She occupied herself with silence and prayer. Nevertheless She rendered a great pastoral service. […]
For the Apostles, the Theotokos was a pillar of support whose prayers they hearkened to, and whose insights and contributions to the preaching of the Gospel they embraced. Thus, through her prayer and co-operation with the Apostles She helped, most significantly with the work of mission. […]
She offered to us the most powerful medicine for our illness:namely, She became the cause of the greatest happiness the world will ever know – She gave birth to the incarnate Christ. […]
The regeneration of just one person can give rise to the greatest clamour in all the universe. The hesychasts bear testimony throughout the ages to the work of missions by their mere existence, their prayers and teachings. They bless and sanctify the world even after their death, through their holy relics.
Thus it is within silence that the most dynamic action takes place.
Metropolitan Hierotheos Vlachos in “Orthodox Spirituality”, chapter 7.
THE ARCHANGEL Gabriel was sent from heaven, to proclaim to the Virgin the good news of the conception; and coming to Nazareth, he meditated in himself with astonishment upon the marvel:
Oh, that he who dwells in the heavens without being contained there, be born from a Virgin! Oh, that he who has heaven for his throne, and earth for his footstool, be contained within a woman’s womb! That he upon whom the six-winged and the many-eyed cannot gaze, should please to be given flesh from her at a mere word!
The Word here with us is God’s. Why then do I stand, and do not speak to the maid?
HAIL, O full of grace! The Lord is with thee!
Hail, pure Virgin.
Hail, Bride without bridegroom.
Hail, mother of Life.
Blessed is the fruit of thy womb.
