The Holy Apostle Hermes was a bishop in Philippopolis, Thrace. He was a Greek, but he spent some time in Rome. The holy Apostle Paul greets him in the Epistle to the Romans (Rom 16:14). The Apostle Hermes endured much grief from the pagans for preaching the Gospel, but he died in peace.

According to Tradition, Saint Hermes is the author of The Shepherd, an instructive book based on revelations from angels.
