Source of Christian attitudes towards fantasy and role playing games I've heard many stories of people who abandoned their role-playing hobby, or burned their fantasy book collections, on the grounds that these were opposed to their Christian faith.

What is it that causes some Christians to be concerned about fantasy and role-playing? What are the sources** for these concerns?

**Not just Biblical sources, but also the people that promoted the concern within the Christian community.
I have never been heavily involved in fantasy or role playing games, but I've had plenty of friends who were. A couple of them have given it up for one reason or another.

The most applicable of these cases was somebody who was convicted about the usage of their time spent in the gaming world not being productive or glorifying to God. There was no objection on principle to the activities, but they were convinced that there were better things to be doing with their time. Besides ... in light of the grace they received from Christ, they wanted to spend their sharing that grace with others. The real world is hardly a boring place, and the way it comes alive in light of the Gospel is enough to inspire and drive even the most active imagination.

I also have friends (who I respect) that think their time spent in role playing games or fantasy worlds is well balanced and the interaction with people a valuable investment. I don't know enough about the culture of gaming to know how easy/hard/valid/invalid this is, but I have to imagine as a past-time and social activity it doesn't have to be a bad thing.

That being said, the content of what you are participating in needs to be considered. Considering movies as a whole one might conclude that watching films is permissible, but then if all you watch is trash, obviously you've twisted some truth into a lie. If the content of the world you are participating in is not wholesome, as a Christian you would have no business continuing.

I think this might fall under the umbrella of Paul's admonition about meat sacrificed to idols. All things are permissible but not all things are beneficial. That's a judgement call you'll have to make. Is your time spent in gaming or role playing giving the most glory to God that you can give with your life?
