As Mr. Helbert said in a recent thread, "We need fewer professional theologians, ideologues, and nit pickers, who strain at gnats, and more pastors, teachers, deacons, and missionaries who are willing to get into the trenches and do the grunt work of coming along side people who have everyday needs."
While I agree with this sentiment there needs to be a balance of recognition that these doctrines effect some of these areas you are concerned about. There is a balance. Orthodoxy leads to Orthopraxy. As I noted earlier, a Pastor friend of mine who does what you are calling grunt work was asked to go pray for a City Counsel meeting and was challenged by one of his fellows to consider if he was mixing the two kingdoms. You would be surprised who those people were.
