On the Byzantine liturgical calendar today we commemorate the holy apostles, Erastus, Olympus, Rodion, and their companions. Remembered as apostles and little heard of unless you are a student of sacred Scripture.
When St Paul wrote his letter to the Romans he was staying in Corinth. Erastus was the treasurer of that city and a supporter of St Paul. Rodion, or Herodion, is greeted by Paul as a compatriot in the same letter. Olympus is another of the saints singled out for a special greeting. He and his companions were the core of the Church in Rome. (NS).
Erastus, Olympus, Rodion, and their companions, pray for us.
