In my church experience, there is a pastor who gives sermons and pastoral care to a diverse group of people. Some of the people receiving the the pastor don't have a clue and would accept an “interpretation of the day”, but there are many members that are as well versed in the Bible as the pastor and well grounded in their faith. These may be called deacons, elders or other names, but in the churches I have attended, they have the power to take a pastor to task or ask them to leave if they don't hold true to the faith.
I was in a Sunday School class yesterday being led by the pastor. He mentioned something he did daily in prayer. I asked him what the basis was in scripture for it. That led to the remainer of the class being a polite discussion about prayer and spiritual warfare.
In most of the Baptist congregations I’ve been in, the pastor is respected but HARDLY unchallenged. Happily, most of the pastors I’ve known have been godly men who welcomed someone saying, “But where is that found in scripture?”, or “Does that conflict with this passage...?”
