Episcopate and the Barred Emperor
Babylas was bishop of Antioch in the third century, counted as the twelfth holder of that ancient see and the successor of Zebinnus. His episcopate is generally placed in the years surrounding the reign of the emperor Gordian III.
The episode for which he is best known is his refusal to admit a pagan emperor into the church because of the ruler's bloodstained or sinful conduct. The sources do not agree on the emperor's identity: John Chrysostom, who preached on Babylas, leaves him unnamed; the Acts of the Martyrs name Numerian; and many scholars favor Philip the Arab, whom the historian Eusebius reports was barred by a bishop from the Easter vigil, with later legend connecting the demand for penance to Philip's involvement in the death of the young Gordian III.
