This sermon is meant to build on the foundation of Dennis Luker's sermon: Jesus Christ--The Head of the Church. The purpose is to relate what we can do and should do as well as what not to do when there are problems that threaten the unity and peace of God's Church. We know that Satan wants to divide and destroy us. We must do everything we can to resist Satan's influences and humbly work toward reconciliation, peace and unity so we can powerfully carry on with God's Work.
