Thanks for the email.
First let me say that no one is ever going to agree on what is appropriate and what is not for viewing. And most people who do state what is appropriate, state it as a fact. You can find my 2 cents on this issue on my video clips page where I talk about my thought on R-rated films and discernment: http://www.thesource4ym.com/videoclips/r-moviesbyjon.asp
And I must say, you raise a good question. "If something isn't good to play in the church ... is it good to watch it anywhere?" Again, people's traditions are different regarding their "sanctuary." Many churches today use gymnasiums or school facilities for church gatherings, a pretty casual atmosphere, where videos and skits are allowed to stimulate thought or discussion. Others have a designated Sanctuary that is "Sacred" and is meant strictly for worship. Much of the worship styles people use today might be an "abomination" in many of these sanctuaries. So the answer isn't simple or one we all will agree on.
Bottom line- we should use discernment with what we feed in our heads. And when we go to worship God, our focus should be on Him. We should avoid anything that distracts.
Hope that is a help.
