I sense it's just a matter of time and all churches will lose their tax exempt status ... especially regarding property tax exemptions. I can't see that the "non-church attending majority" will tolerate this much longer. It's already being challenged ...
Assuming that Past the Wishing is correct, how do you think this loss of tax-exempt status will change the church?
One word: downsizing.
Fewer churches will be able to afford to own their buildings.
Fewer churches will be able to afford to add on to the buildings they already own.
More small or new churches will meet in homes or in free or low-cost venues.
I see these changes as a good thing. Call me a socialist ( ;) ), but why pay money for a building when you could spend that money helping people who don't have food to eat or a place to sleep at night?
