At the Aposticha, the stichera from the Pentecostarion.

But if this day fall within the Apostles’ Fast, we chant these stichera of the apostles, in Tone I: Spec. Mel.: “O most lauded martyrs…” —

Now & ever…: Doxasticon from the Pentecostarion, or the theotokion: “O unwedded Virgin who ineffably conceived God in the flesh…”

Troparion, in Tone III —

Your proclamation of salvation hath gone forth into all the earth, O apostles, seers of God, and hath illumined the souls of the lost and brought unto Christ men enlightened by grace. Wherefore, pray ye, that He grant unto our souls peace and great mercy.

Stichos: Their sound hath gone forth into all the earth, and their words unto the ends of the world.

O all-radiant beacons of Christ, most precious vessels, all-wise ones, who through faith have come to contain the effulgence of the Spirit, pillars of the Church, all-glorious heavens declaring the glory of God: entreat Him, that He grant unto our souls peace and great mercy.

Stichos: The heavens declare the glory of God, and the firmament proclaimeth the work of His hands.

O blessed one, ye brought to Christ God the nations, delivered by the blood of Him Who was well pleased to be born on earth and Who of His own will endured the Cross and death, O glorious ones. Entreat Him now, that He grant unto our souls peace and great mercy.

Glory…, in Tone VIII —

O all-praised Barnabas, apostle of the Savior, receptacle of faith, son of consolation, calm of the tempest-tossed, as thou hast boldness, pray thou unceasingly, that our souls be ­preserved in peace on the day of thy ­commemoration.

O holy apostles, entreat the merciful God, that He grant our souls remission of ­transgressions.
