St Andronicus was made Bishop of Pannonia, but his preaching also took him and St Junia to other lands, far from the boundaries of his diocese. Through the efforts of Sts Andronicus and Junia the Church of Christ was strengthened, pagans were converted to the knowledge of God, many pagan temples closed, and in their place Christian churches were built. The service in honor of these saints states that they suffered martyrdom for Christ.
In the fifth century, during the reign of the emperors Arcadius and Honorius, their holy relics were uncovered on the outskirts of Constantinople together with the relics of other martyrs at the gate of Eugenius (February 22).
It was revealed to the pious cleric Nicholas Kalligraphos that among the relics of these seventeen martyrs were the relics of the holy Apostle Andronicus. Afterwards, a magnificent church was built on this spot.
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 Second Tone
As notable companions of the Apostles and true ministers of Jesus, ye proved to be sacred heralds of His condescension; for having received the grace of the Spirit, O glorious Andronicus and Junia, ye shine like lamps unto the ends of the world.
Podoben: “Seeking the highest...” / Let us praise the apostle of Christ, Andronicus, / the all-radiant star who illumined the nations with the light of the knowledge of God. / Together with him we praise all-wise Junia, / who shone with righteousness. / To them let us cry out: / “Unceasingly pray to Christ God for us all.”
