Well, first I looked up the definition of the word "Superstition" and this is what two dictionary sources say:
(W-M Dict.)-
1 a : a belief or practice resulting from ignorance, fear of the unknown, trust in magic or chance, or a false conception of causation
b : an irrational abject attitude of mind toward the
supernatural, nature, or God resulting from superstition
(TheFreeDictionary.com)
- 1. An irrational belief that an object, action, or circumstance not logically related to a course of events influences its outcome.
1 Peter 2:15 tells us what God thinks of "ignorance"
"For this is the will of God, that by doing good you should put to silence the ignorance of foolish people." - English Standard
Version
Acts 17:22-31 There may have been a time that God overlooked the "ignorance" or superstitious faith of the "men of Athens". Verse 30, tells us that God has since then set a day and requires all to repent. That means turn away from practicing superstitious faith that is contrary to what he requires of his followers.
(verse 31) "For he has set a day when he will judge the world with justice by the man he has appointed. He has given proof of this to everyone by raising him from the dead." - New International Version
Since Christ's resurrection, we are no longer ignorant. And ignorance will not be an excuse for not knowing what the Heavenly Father expects and demands from us. So, I guess "Superstition" or superstitious thinking is just not something a faithful Christian would choose to buy into.
