The belief in the Devil has deep historical roots, evolving from polytheism in ancient Israel to the more defined notions of Satan in Second Temple Judaism and early Christianity. Robert Muchembled highlights this continuity, arguing that the Devil was pivotal in European life since the Middle Ages. The article explores key developments during the First and Second Temple periods, particularly how evolving conceptions of evil and suffering led to the emergence of Satan as an explanatory figure. Scholars like Carl Braaten contend that Christianity cannot easily separate itself from this belief, suggesting that interpretations of evil influence modern religious discussions and conflicts.
