Roger Olson writes that the most pernicious heresy in American Christianity is the desire to be respectable.
In my opinion, the main way is that we expect our pastors (and other Christian leaders) to comfort, encourage and support us and never seriously challenge us to the core of who we are. Most pastors know very well that if they do that, their job will be in jeopardy.
Another way is the influence of money and power in church life. Churches usually choose successful businessmen to be their lay leaders and they are not always the most spiritually-minded people of the congregation.
Yet another way is “professionalism” in worship. Many churches hire people, whether Christians or not, to sing in their choirs, play their organs, etc. Appearance and polished performance become more important than real Christian community (participation) and spirituality. Ordinary people of little beauty or talent are rarely, if ever, asked to participate “up front.” How far we have wandered away from 1 Corinthians 14:26!
