Why are so many churches worried abou the way you dress?

Who cares? As long as my body is covered properly, don't worry about it! I mean I do dress decent, but I don't care what others wear to church. That is one of the least important things. I'm sure Adolf Hitler had a decent wardrobe. Obvioulsy, that didn't do him much good did it? lol... I should not have to dress like a nerd or crooked politician/dictator in order to find salvation. Some even say its a sin to have a beard. Well, I don't believe that either. I mean when you begin adding things to the word of God that don't belong there you are headed for trouble. Just like communions. I have heard people condemn catholics for drinking wine. Guess what??? They did drink wine in the Bible! It wasn't g juice! It was the real deal. The word "drunk" is found all over the word of God. Mainly saying it is sin, and it is! But if I drink wine for communion, that is sacred. And I believe in using wine because that is what Jesus said to use. He did not say to remember the g juice as his blood he said remember the wine as his blood. BTW, Im not Catholic. But I think that many religions say things that are simply not so.
