Term
IDOL
Definition
Any creature that is given divine honors. It need not be a figure or representation, and may be a person. In fact, it may be oneself, or some creation of one's own mind or will. An object becomes an idol when it is treated as an end in itself, with no reference to God. (Etym. Latin idolum, image, picture, idol; from Greek eidolon, phantom, idol.)
