Definition: In Greek, "antimaniac" means someone who is overly enthusiastic or prone to delusions. It's a word used in biblical times by Jesus as he spoke of those who were heedless and not grounded in reality. The Greek term translates literally as, "one who has no sense of the truth," suggesting that they are devoid of any guidance from God. This phrase became synonymous with someone who is untruthful or reckless, often leading to their own downfall.
