Opposed to or effective against demonic possession or demonic influence; having the power to repel demons.
From anti- (against) + demoniac (from demon, from Greek daimon, spirit, + -iac, affected by). This term belongs to theological and historical contexts rather than modern psychology.
In medieval and Renaissance texts, antidemoniac rituals, objects, and charms were serious business—holy water, salt, crosses, and prayers were all considered antidemoniac defenses, and the word shows how people materialized their beliefs about invisible spiritual warfare.
