I'm no Bible thumping holy roller but I do know that if you TRULY understand what it means to be a Christian, you don't go in for the evil aspect of Halloween. I don't think what the pastor said and did is appropriate though. He sounds a little over the top to me.
[ What is life? It is the flash of a firefly in the night. It is the breath of a buffalo in winter time. It is the little shadow which runs across the grass and loses itself in the sunset. - Crowfoot, 1890, on his deathbed. ]
