The holy Apostles Quartus, Erastus, Sosipater (April 28), and Tertius (October 30) were disciples of Saint Paul. The Apostle to the Gentiles speaks of Saint Quaratus in the Epistle to the Romans “And Erastus, the city treasurer, greets you, and Quartus, a brother” (Rom 16: 23).
Saint Quartus endured much suffering for his piety and converted many pagans to Christ, dying peacefully as a bishop in the city of Beirut.

Holy Apostles, Erastus, Olympas, Herodion, Sosipater, Quartus and Tertius, / entreat the merciful God, / to grant our souls forgiveness of transgressions.
Kontakion — Tone 2
Illumined by divine light, O holy apostles, / you wisely destroyed the works of idolatry. / When you caught all the pagans you brought them to the Master / and taught them to glorify the Trinity.
