During the 70`s and 80`s the congregations I was in their were a number of cases where supposed demon action affected some members of the congregation and the Elders were involved in counselling and advising the members how to be free of it.
Often times it was suggested they get rid of something that was purchased through garage sales or anything that had to do with eastern culture .Other times it had to do with "suspect" music, the word going around then was backward masking, playing records in reverse had demonic sayings on them . Another time trying to burn records that could not be consumed by fire . .One bro,was into books on Egyptology and he was experiencing demon attacks,so he got rid of his books on advisement.
We had the smurf story doing the rounds as well as an Elder relating an experience of a brother who tried to get rid of an object by throwing it out of his house only to have it rebound back inside.
A sister also complained to the elders she was being sexually abused by the demons ,I dont know the outcome of that one.
Their was one Elder who was quite adept at applying scriptures but was a bit obsessed with anything demonic.
I was with him in FS one day when we called on a Pastor of a church and he tore ribbons off of him with his use of the Bible .He could debate the bible with the best of them.
However I kid you not he seriously thought "Skippy The bush Kangaroo" had to be demon possessed to do what he did. (An Australian kids TV show)
