St. Peter was made bishop of Ravenna as the result of St. Peter’s appearing to Sixtus III. In the fifth century St. Peter was one of the great bishops who defended the purity of Christian doctrine against the heresy of Eutyches. He preached untiringly to his people. His eloquence and the soundness of his teaching earned him the name of Chrysologus, which means “mouth of gold.” He died at Imola in 450.
