First, understand that I agree with what you are saying. My point about weak doctrine relates to the fact that American Protestants* are living in what Francis Schaeffer described as an "Evangelical Ghetto."

We are more interested in elevating ourselves above where we truly are, and that lowers our estimation of who God is.....
