Stephen of Hierapolis
Stephen of Hierapolis (, fl. 600 AD) was a bishop of Hierapolis Bambyce, Syria. Stephen was the author of a hagiography of St. Golindouch, who was his guest in Hierapolis after escaping martyrdom under Hormizd IV.

Based on that text, we can conclude that Stephen was a Chalcedonian.
