In general, a complex of beliefs, cultic practice, and ethical demands in a system related to God or gods. More narrowly, the reference is to Judaism in Acts 26: 5, but the same Greek noun is also used in Col. 2: 18 of the ‘worship’ (NRSV) of angels. Christian faith in 1 Tim. 3: 16 (‘religion’, NRSV) is denoted by a different Greek word. Two sorts of ‘religion’, bad and good, are contrasted by James (1: 26, 27).
