Peter Chrysologus, Italian bishop and saint (b. 380)
Peter Chrysologus (Greek: Ἅγιος Πέτρος ὁ Χρυσολόγος, 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.
