Amplias, Apellos, Stachyos, Urbanos, Aristovoulos and Narcissos of the 70

Of these holy Apostles, Stachys became the first Bishop of
Byzantium, consecrated by the Apostle Andrew. Having shepherded his people
for sixteen years, he reposed in the Lord. As for the others, each
one shone forth in the episcopal see appointed to him.

Apolytikion in the Third Tone
O Holy Apostles, intercede to our merciful God, that He may grant
our souls forgiveness of sins.

Kontakion in the Plagal of the Fourth Tone
Come, let us duly praise Apelles and famed Aristobulus, the wise
Apostles, with Urban, Narcissus and Stachys, and blessed Amplias, as the
most sacred treasures of the All-holy Spirit and the far-shining beams
of Christ, the Sun of Glory, whom God brought together by His grace.
