Removing A Man From Church That Contradicts

This a second sermon showing the role of the shepherd and Church discipline. The first sermon was preached the same day entitled 'Are Shepherds Just Teachers'. This is a message that many have never heard before and will be foreign to the ears of many. Question: Could you throw out a dear, close friend and have nothing to do with that man, if he was contradicting 'what your church most assuredly believes'? Do we trust the way God says to handle it it, or do we by our excuses and actions show that we have better knowledge than the god we say, is all knowing and perfect?
