Their story
Sergius and Bacchus were distinguished army officers who suffered cruel torments and death under Maximian at Rasaphe in Syria. Theodoret (5th-century bishop and church historian), Evagrius, Gregory of Tours and Bede (the English monk-historian, d. 735) all mention them.
In 431 Alexander, bishop of Hierapolis, built a church over their tomb. Justinian fortified the town and renamed it Sergiopolis. Butler notes that no authentic acts of their martyrdom survive.
