Sergius (or Serge) and Bacchus were fourth-century Roman Christian soldiers revered as martyrs and military saints by the Catholic, Eastern Orthodox and Oriental Orthodox Churches. Their feast day is 7 October. According to their hagiography, Sergius and Bacchus were officers in Galerius' army, and were held high in his favor until they were exposed as secret Christians. They were then severely punished, with Bacchus dying during torture, and Sergius eventually beheaded. Sergius and Bacchus were very popular throughout Late Antiquity, and churches in their honor were built in several cities, including Constantinople and Rome. The close friendship between the two is strongly emphasized in their hagiographies and traditions, making them one of the most famous examples of paired saints. Legend The story of Sergius and Bacchus is told in the Greek text known as The Passion of Sergius and Bacchus. The story is ostensibly set during the reign of Roman emperor Galerius (305 to 311), though it contains a number of contradictions and anachronisms that make dating difficult.

Galerius then sent them to Barbalissos in Mesopotamia to be tried by Antiochus, the military commander there and an old friend of Sergius. Antiochus could not convince them to give up their faith, however, and Bacchus was beaten to death. The next day Bacchus' spirit appeared to Sergius and encouraged him to remain strong so they could be together forever. Over the next days, Sergius was also brutally tortured and finally executed at Resafa, where his death was marked by miraculous happenings. Popularity and veneration Veneration of the two saints dates to the fifth century. A shrine to Sergius was built in Resafa (renamed Sergiopolis around 425), but there is no certain evidence for his or Bacchus' cult much older than that. Their cult grew rapidly during the early fifth century, in accordance with the growth of the cult of martyrs, especially military martyrs, during the period. The Resafa shrine was constructed of
