The holy, glorious, all-laudable Apostle Tertius (also Tertios) is numbered among the Seventy Apostles. He wrote down the Apostle Paul's letter to the Romans, and was Bishop in Iconium after the Apostle Sosipater. He died a martyr. The Church remembers St. Tertius on October 30 and November 10.
- Holy Apostles, Erastus, Olympas, Herodian, 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.
