In response to the, "I'm against Halloween" position:
I don't think Halloween was "conceived in evil." Every culture finds a way to cope with death. American Halloween is a McDonald's pop-culture version of a mix between All Hallow's (All Saints') Eve and the world's morbid fascination with death, sorcery and the macabre. Of course lots of bad things are toyed with at Halloween. Yes, it is dangerous for secular people to toy with the occult. Of course, we shouldn't dress up like we're on Satan's "team." This doesn't mean total rejection of the holiday is the best approach for the church. Reform it to the intent the church had for it. Why not celebrate the saints, and that we can triumph over and jeer all these evil powers, which really do exist? Far better to address them and ridicule them, than to run and hide from them, as if the victory is not won at the cross of Christ (Colossians 2:15). I'd rather show the world that victory and triumph, than show them we're against it and don't do it.
What's hardest to take is when all the "I'm against Halloween" person can hear from my above paragraph is that I'm just more worldly than they are. Sigh.
