I’m not sure that “The Church” has as much spare money as you think they do, John. Your average local church counts itself lucky if they can keep the lights on.
Obviously the “big denominations” have the ability to act as an aggregator, taking a small slice of the local collection plates and using it for political action. But, they kind of do that anyway, which is my point.
Freedom matters, and sometimes freedom means giving voice to somebody you’d rather not give it to. Works both ways.
