Is your church essentially a faith-based non-profit business?

I ask this because I think many Christians, including pastors, would say, "yes." But I can't really find anything in scripture that would put a church in that category. Yes, the IRS might do so, but if you rely on the IRS for your church identity you might want to look elsewhere. The church isn't a business but a body, the pastor is not an executive but a shepherd, you don't exist as a church to produce a product but you live to be a people. Our confusion on this is likely part of why most pastors and church members don't spend more than 5 years in a church.* Why not move on if it is just a non-profit business? There will always be another church/business that provides a better product or does things more efficiently. But that isn't the point, is it?
