Yes, I too used to participate in this holiday.

I read where Antone Lavey that founded the Church of Satan in 1966 called Halloween the third highest day on the satanic calendar for Satanists. Antone Lavey wrote this in his book called, The Satanic Bible. We don't want to be celebrating the same things that the satanic are celebrating.

“Do not participate in the unfruitful deeds of darkness, but instead even expose them” (Ephesians 5:11).

Thanks for bringing up this subject.
