Sunday of the Forefathers - Troparion & Kontakion
Troparion — Tone 2
By faith You justified the Forefathers, / when through them You betrothed Yourself beforehand to the Church of the Gentiles. / The saints boast in glory, / that from their seed there is a glorious fruit: / she who bore You without seed. / By their prayers, O Christ God, save our souls.
Kontakion — Tone 6
(The Original Melody)
You did not worship the graven image,  /  O thrice-blessed youths,  /  but shielded by the ineffable
Essence,  /  you were glorified in your trial by fire.  /  In the midst of the unbearable fire you called
upon God, crying:  /  "Hasten, O compassionate One.  /  and in Your mercy, come to our aid,  /  for You
can do so if You will."1
1 Luke 5:12.
