“Apparitions are of Satan.”
Correct. My cousin is a minister in Italy and relates stories of many occurrences, apparitions, etc., that people are sucked in to believing. Clearly demonic. Bottom line, the Bible has revealed everything we need to know. Extra-Biblical “revelations”, mumbo-jumbo, vain repetitions, are of Satan.
My view on extra-Biblical revelation is that if it doesn't pass the test by conforming to Scripture, its wrong period, no questions asked. It's a given. It should be rejected.
If it passes the test and conforms to Scripture, then it can be found IN Scripture, is redundant and wasn't needed anyway and I would find it suspect and wonder about the motivation of the person giving it.
Scripture contains all we need to be complete, equipped for every good work.
