There has been much debate in religious communities about whether Halloween is some Satanic festival and if it is okay for Christians or any religion to honor/celebrate October 31st.
Surprisingly, Halloween is partially a Christian holiday and partially a pagan one. The ancient Celts celebrated Samhain (pronounced Sow-an) a pagan harvest festival, another 2000 year old harvest festival/New Year celebrated in France and the UK and the Catholic church's All Saint's Day which honors those martyred for Jesus Christ.
Over the years, they were melded together on the same date. Originally, All Saint's Day was May 13 but the pope changed it to November 1st. Some say it was because Vatican City didn't want people to crowd there in the summer when it would be very hot in Italy, but more than likely, the church wanted to have their holiday supercede the Pagan rituals of October 31st. The danger of that is obscuring what is what and what rituals belong to whom.
Attached is a television special on the origins of Halloween. Regardless of what your religious preference is, you should let your conscious be your guide based on an informed decision after considering the facts. Enjoy!
