Much of the Christian church deals with communion on a purely physical level. Paul teaches us that true communion with God is fellowship with him in the word of God and hearing what it is He has to say. We can examine ourselves by a cracker and live however we wish, or we can examine ourselves by the word of God and realize that our life must come into line with His expectation. If we'll examine ourselves, and judge ourselves, then God doesn't have to. When He does deal with an issue, it's for our good only. 1 Cor. 11, 2 Cor. 7
