Superstition is Idolatry because it is based on not acknowledging God. The Webster’s Dictionary definition of Superstition is: 1. “any belief, based on fear or ignorance, that is inconsistent with the known laws of science as true and rational; esp., such a belief in charms, omens, the supernatural, etc. 2. Any action or practice based on such a belief 3. Such beliefs collectively.” We have many common superstitions like, beginner’s luck, a black cat crossing in front of you means bad luck, breaking a mirror means seven years of bad luck, knock on wood, cross your fingers, and there are many more. They are the minor Superstitions, with the more serious concerning Astrology, Stargazing, Tarot Card reading, Palm Reading, and other Fortune Telling efforts. Those are Idolatry, to be avoided by believers. Paul calls those things “Old womanish myths”
