Then should the Church let people come in naked if they want to just because they are glad that they at least are attending? What’s wrong with saying no jeans, shorts for men or women, except in the case of children under 6? When there was a dress code for attending Mass back when I was growing up, and that included no sleeveless blouses, Mass attendance was much higher than it is now.
So your assertion is that attendance was higher because there was a dress code? Seriously?
What's wrong with implementing a dress code is that: (a) our job as Christians is supposed to be encouraging more people to follow Christ, not discouraging people from coming to Church; and (b) how is it our business to set a dress code? The Church belongs to Christ, not to me and not to you. If someone comes to my church in a suit or jeans or filthy rags, I don't care, we don't care, and I'd even venture to say that God doesn't care. What matters is seeing unbelievers converted to become committed followers of Christ. If you've lost sight of that because you are too bent out of shape because someone is wearing jeans, I'd suggest that your priorities are out of whack.
Back in the 30's men wore suits and ties to major league baseball games and the woman wore dresses that would be considered formal wear today.
We are becoming a casual society and I have no problem with that.
