I found this really great article about Christians and Halloween. The author talks about our options, most of which are extremes. Here’s the part I like:
“There’s another option open to Christians: limited, non-compromising participation in Halloween. There’s nothing inherently evil about candy, costumes, or trick-or-treating in the neighborhood. In fact, all of that can provide a unique gospel opportunity with neighbors. Even handing out candy to neighborhood children–provided you’re not stingy–can improve your reputation among the kids. As long as the costumes are innocent and the behavior does not dishonor Christ, trick-or-treating can be used to further gospel interests.
