Peter Chrysologus (, Petros Chrysologos, "Peter the Golden-worded"; c. 380 – c. 450) was Bishop of Ravenna from about 433 until his death. He is known as the “Doctor of Homilies” for the concise but theologically rich reflections he delivered during his time as the Bishop of Ravenna. He is revered as a saint by the Roman Catholic Church and the Eastern Orthodox Church; he was declared a Doctor of the Church by Pope Benedict XIII in 1729. Life Peter was born in Imola, where Cornelius, bishop of the Roman Catholic Diocese of Imola, baptized him, educated him, and ordained him a deacon. He was made an archdeacon through the influence of Emperor Valentinian III. Pope Sixtus III appointed Peter as Bishop of Ravenna circa 433, apparently rejecting the candidate whom the people of the city of Ravenna elected. At that time Ravenna was the capital of the West, and there are indications that Ravenna held the rank of metropolitan before this time. The traditional account, as recorded in the Roman Breviary, is that Sixtus had a vision of Pope Peter the Apostle and Apollinaris of Ravenna, the first bishop of that see, who showed Peter, a young man, the next Bishop of Ravenna. When a group from Ravenna arrived, including Cornelius and his archdeacon Peter from Imola, Sixtus recognized Peter as the young man in his vision and consecrated him as a bishop. People knew Peter Chrysologus, the Doctor of Homilies, for his very simple and short but inspired sermons, for he was afraid of fatiguing the attention of his hearers. His piety and zeal won universal admiration. After hearing oratory of his first homily as bishop, Roman Empress Galla Placidia supposedly gave him the surname Chrysologus, meaning "golden-worded." His sermons are historically significant in that they reveal Christian life in fifth-century Ravenna. The Emperor's mother, Galla Placidia, patronized many projects of Bishop Peter. In his extant homilies, Bishop Peter explained Biblical texts briefly and concisely. He also condemned Arianism and Monophysitism as heresies and explained the Apostles' Creed, the mystery of the Incarnation, and other topics in simple and clear language. He dedicated a series of homilies to John the Baptist and the Blessed Virgin Mary. Peter advocated daily reception of Eucharist. He urged his listeners to confide in the forgiveness offered through Christ. His surviving works attest to the Catholic Church's traditional beliefs about Mary's perpetual virginity,
