Agreed. So much of this is about being man-centered, not God centered. We want to be greater than God, greater than His church. We view ourselves as the omnipotent interpreter of His Word.
I'm not advocating the Roman Catholic view of total Church authority - but the point is a valid one, that we join a church yet do not submit. Whether this be a denomination, etc. we pick and choose our believes in our own little omnipotent manner.

Grace is not common.
