John Angeloptes was the Bishop of Ravenna from 430 to 433 and Metropolitan of Aemilia and Flaminia.
[1] He was the successor to St. Ursus of Ravenna.
John's epithet of 'Angeloptes' denotes his gift of having had the opportunity to see an angel; more specifically, he was reported to have had an angel help him in conducting the Divine Liturgy.
[2] Due to an error in historical transmission, he is often confused with his counterpart John II.
[3] His feast day is on 27 November.
