Exactly. This is where the rubber will meet the road. Those churches willing to give up the funds will stay true; others will not. The choice will be the same choice 2000 years ago: God or mammon.
Since the majority of “churches” in my area are mega churches I totally believe they will stay 501c3 and go along. Those places costs millions, have full schools and rec centers, etc. They won’t sacrifice any money. They’ll sacrifice their so-called “values”.
