Herodion of Patras (also Herodian or Rodion; Greek, Modern (1453-);: Ἡρωδίων, Ἡρωδιανός, Ῥοδίων) has been thought by some to have been a relative (συγγενής) of Saint Paul, as in a greeting Paul calls a Herodion a sungenēs in Romans 16:11. But Paul uses the term συγγενής (sungenēs) for fellow Jews in Romans 9:3. So συγγενής (sungenēs) can mean relative even as broadly as fellow Jew. According to tradition, Herodion of Patras was numbered among the Seventy Disciples and became bishop of Patras, where he suffered greatly. After beating, stoning, and stabbing him; they left him for dead, but St. Herodion arose and continued to serve the Apostles.
He was beheaded with Olympas in Rome while they were serving Saint Peter on the same day that St. Peter was crucified. His feast days are celebrated on January 4 among the Seventy, April 8, and November 10.

Holy Apostles, Erastus, Olympas, Herodian, Sosipater, Quartus and Tertius,
entreat the merciful God,
to grant our souls forgiveness of transgressions.

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.
