δαιμόνιον (daimonion)

The Greek word daimonion refers to a divine being, but in the New Testament it specifically denotes evil spirits that oppose God. While classical Greek used the term for neutral or even benevolent lesser deities, the biblical authors repurposed it to describe malevolent entities under Satan’s authority. This shift aligns with the Old Testament view of foreign gods as demonic forces, a connection Paul makes when he writes that pagan sacrifices are offered to demons, not to God (1 Corinthians 10:20).

These spirits are portrayed as active agents capable of entering and controlling human beings, causing physical and mental distress. Jesus frequently encounters them in the Gospels, casting them out from individuals who are "demon-possessed" or speaking through them. The texts describe these entities with fear and authority, noting their recognition of Jesus’ identity and their eventual expulsion into swine or desert regions (Luke 8:30-33). The term underscores the spiritual reality behind physical affliction.

Etymologically, daimonion derives from a root meaning "divine," reflecting an ancient worldview where the world was populated by various spiritual powers. By the time of the New Testament, however, this broad category had narrowed sharply to identify only those spirits in rebellion against God. Translators typically render it as "demon" or "devil," capturing its role as a hostile force that Jesus came to defeat and cast out.
