Where in the bible does it discuss the proper attire to wear to a church building? Am I allowed to pray in my underwear, or must I put on a suit before I approach God in prayer?
Conditional worship. Once you establish a Worship Experience Based on Comfort, that becomes the condition for future worship.
There's nothing wrong in wearing jeans or sweats to church, if it's the best that you have ("Give of your best to the master"). The point is, if someone is saying "UNLESS I can wear sweatpants, I won't go.", then the problem is their motives. That's the attitude of conditional worship that the seeker-sensitive folks perpetuate because they're winning people to fleshly comforts.
Unless the church has a fooseball table and daycare, I won't go.
Unless the church has jump-in-the-aisle music, I won't go.
If I can't drink a coke during the service, I won't go.
