Synaxis of the Most Holy Mother of God - Troparion & Kontakion
Troparion — Tone 4
O Most Pure Mother of God, your holy Synaxis is adorned with many diverse splendors; / and gifts are brought to you by many peoples of the world, O Lady Theotokos. / In your mercy, loosen the bonds of our sinfulness, and save our souls.
Kontakion — Tone 6
He Who was begotten before the morning star by the Father without a mother / is incarnate of you today on earth without a father. / Therefore, a star announces the glad tidings to the Magi, / while Angels and shepherds sing of your undefiled child-bearing, O you who are full of grace.
(In some Greek sources this Kontakion is chanted in Tone 8, and is listed as the Original Melody.)
