Which one do you worship, God or "culture"?
I worship G-d of course. However, it seems to me that the "jeans anyplace, anytime, crowd" is much more beholden to the culture that those who dress more appropriately for whatever the occasion demands of them. It seems to me that in this day and age, it is more "counter culture" to wear a dress or suit to church than to wear jeans. (It certainly would be at Chena's Church)
