"As a Christian, I believe it is a sin to go to the movie theater."
Yep. That's what Jesus said.
"We are to be in the world, but not part of it."
Go join a convent then.
"To go to the movie theater is a bad testimony."
What the fuck does "testimony" have to do with going to a move?
"Oh, look at me! I don't go to movies! See what Jebus could do for you, too!"
"Not all movies are bad, but the majority are."
Well, yes. But that's just because the movie industry is greed driven and the masses just want entertainment and don't much care about the quality.
"Just think, would Jesus go to a movie theater? No!"
Yeah. The guy who hung out with lepers, prostitutes, tax collectors and various other unsavory characters wouldn't go to a movie theater. I guess he wouldn't want to ruin his reputation or something.
"And neither should Christians."
You shouldn't be doing a lot of the things you likely do repeatedly.
"If a good, clean movie does come out, buy it or rent it on DVD. It will come out very quickly after it's run in the theater."
So, it's not the movie itself but the fucking building that you have a problem with? Is that it? This is one of the more strange things I've seen someone say.
Maybe you're just an agoraphobe who thinks their panic attacks are "Jesus" telling you he's unhappy with you going to a movie.
