Nereus and Achilleus were Roman soldiers in the household of Flavia Domitilla. They were instructed and converted by St. Peter. These two soldiers in turn inspired St. Domitilla to consecrate her virginity to God. Thereupon, Aurelianus, the fiancee of Domitilla, reported all three to the Roman authorities as being Christians. They were martyred out of hatred for Christianity. Pancras, a noble Phrygian youth, came to Rome at the age of fourteen and was martyred in 275 because he refused to offer sacrifices to the pagan gods.
