Celebrated on the Sunday of the Holy Forefathers on the second Sunday before the Nativity.
Troparion (Tone 2)
Through faith You justified the Forefathers,
betrothing through them the Church of the gentiles.
These saints exult in glory,
for from their seed came forth a glorious fruit:
She who bore You without seed.
So by their prayers, O Christ God, have mercy on us!
