It is a deliberate personal choice for me to dress casual at church. I know people who have left services because they felt under dressed and it made them feel like they were not good enough to be in a church. I know of no person that was ever driven from the house of God because someone else dared to dress casual.
I'm calling Bull on your post.
Most churches for the last few decades are so casual that they only person who would feel the need-to-leave the service for being under-dressed is the guy who shows up with no shirt and no shoes. In the past, everyone would expect that they would need to dress up for church, until you and people holding your view taught them otherwise.
You say your casual dress at church is a personal choice. Of that, I have no doubt.
"Therefore, if food causes my brother to stumble, I will never eat meat again, so that I will not cause my brother to stumble." [1 Corinthians 8:13 NASB]
1) Paul called those people who would stumble weak. Are you calling casual dressers weak? (I am.)
2) Paul and Jesus drank wine and ate meat. Their desire not to cause people to stumble did not extend to full abstinence. They coddled people when necessary, but they didn't change their lifestyles to coddle people, as you argue for us to do.
3) Paul taught approvingly of eating meat. His desire not to cause people to stumble did not include
teaching them that eating meat is wrong, but you teach that dressing with reverence is wrong. Casual dress is a contributor to the free fall of American Christianity. You are causing people to stumble.
4) The verse you quote about causing people to stumble concerns Old Testament teaching against non-kosher foods, of which all Jewish converts were raised with. Dressing like a slob has never had any legitimacy.
3) A person with a changed heart seeks praise from God, not from people. [Rom 2:29]
Really? You think someone putting on blue jeans for church is seeking praise from God?????? LOL!
Matthew 22:11 “But when the king came in to look at the guests, he saw there a man who had no wedding garment. 12 And he said to him, ‘Friend, how did you get in here without a wedding garment?’ And he was speechless. 13 Then the king said to the attendants, ‘Bind him hand and foot and cast him into the outer darkness. In that place there will be weeping and gnashing of teeth.’
