When a guest speaker in a major non-denominational church in Ft. Lauderdale made reference to the beliefs of the candidates and who was more aligned with Christian values, someone in the congregation sent a *certified letter* of complaint, as well as several phone calls with complaints. The pastor made a public apology the next week. Me thinks the churches are being monitored by those who believe in The One.
Yes, I believe there are spies in churches. Didn’t little o suggest that they do that? I think I remember that from a while back.
You're close as to "why?" Most pastors in the mainline churches are in their positions at the pleasure of the people in the pulpit. As a pastor, you have to be pastor to all the people, not just those who agree with you. In every congregation there are one or two liberals (Don't ask me how they can be both liberal and Christian). They don't see the contradiction. Mainliners do not "encourage" conservative preaching these days. Sad, but true. Pastors have to stick to Scripture, but one can do pretty well using Scripture alone to make a moral point.
