Violence in video games and movies and gaming does not reinforce a belief that violence is good by themselves. Children and adults are not formed only by the media which they consume and in which they participate. This is precisely why the church needs to engage with these forms of culture, to examine them and to see them for what they are. Not only that, but the church is also responsible then for teaching and reinforcing what is good. If the only voice a young person hears is the one that is based on Hollywood conventions and capitalist calculations, then that is the voice that they will hear. But if they are learning how to live a life of love from their families, from schools, and from the church, they will also gain the skills necessary to make the right decisions in their own lives. When confronted by a situation in real life where violence is an option, they will then have the tools they need to act as people of faith in the world.
Violence portrayed in popular culture is often redemptive violence - a direct contradiction to the non-violent resistance proclaimed and lived by Jesus. So does this redemptive violence play a role in our spiritual development in any way? Or is it just so much chaff we should let blow away from our lives? Does it matter if we participate in it, or is it just harmless fun?
