Sounds like you have a huge problem with the ministers and accountants hired by your congregation!
The Church began in Acts 2. Over the 2,000 years since then, it has morphed into some big business, corporate model that bears no similarity to its beginnings. That's the problem.
Members don't want to study. So we hire "preachers" to do our studying, teaching, thinking, for us. And as soon as the membership gets stupid, then they're ripe for any kind of unscriptural innovation or doctrine.
They're also ripe for preachers to do less and less. Modern preachers are notorious for preaching the same sermons over and over. They just stick in different illustrations, and most members never catch on. Preachers are no different from anyone else. They will do only what they have to, to get by. And as the preacher goes, so goes the congregation.
We need to get away from the corporate church model. Remember, in Romans 16, Paul greeted Aquilla and the church in his "house."
