Pat Robertson (of the 700 Club) has said that when you let your children go trick-or-treating, you're allowing them to participate in Druidic rituals. Is this true?
I think the fear is that children will be drawn into the occult drawn away from Jesus if we let them dress up like Spider-Man and go door-to-door begging strangers for candy.
Do you know of anybody even one person who grew up in the church with loving parents, in a good Christian home, and later became a Satan worshipper because he had gone to a Halloween party as a child? Don't we have better things to worry about?
There are traveling "evangelists" who make a living going from church to church trying to scare the living daylights out of people, trying to create a "Satanic panic." They point out that witchcraft is shown openly on television in shows like "Charmed" and "Sabrina the Teenaged Witch." There are movies such as "The Blair Witch Project" and "The Craft" being shown in our theaters.
If your children are so non-ego-formed that celebrating Halloween or watching "Charmed" causes them to start chanting to the Dark Lord, then my guess is that you failed somewhere as a parent.
Here in the United States, we have the right to follow any religion we choose, no matter how silly. That's what makes America great. If you believe in religious freedom for all people, Christians and Jews and Buddhists and Pagans alike, it doesn't mean you're a liberal. It means you have good sense.
