Are you saying that these mega churches like Osteen’s are not liberal? LOL!
If you are going to use nonsensical terminology, why should I answer?
Olsteen seems like a pitchman to me. Willow Creek puts out lots of good Bible studies that our church uses. My church isn’t a mega-church, but is pretty large and growing. It has traditional and modern services, and a really good pastor that preaches from the Bible. And lots of opportunities for Bible studies, etc.
The leadership is very conservative theologically, but most of the people in the pews are probably liberal in their politics.
