Such churches teach a supranational Christianity; that Christ is above all nations and thus Christianity can’t be branded to any particular Earthly constitutional construct.
I think they understand this country, but they’ll argue that Christ’s mission has a higher priority than country. Warren’s church is said to be veering dangerously close to a “social justice” type of ministry, yet he still angers folks left and right. As long as he does that, he may be doing something right.
The only things Warren is doing right are selling books, and feeding his congregation spiritual cotton candy. I despise him and those like him. Joel Osteen comes to mind.
