text: The purpose of the Church is to teach, govern, and sanctify. 
  
  It needs to work to maintain a unity in its teaching, especially on moral matters.  
  
  Remember, liturgical law is "lower" than moral matters, and can tolerate more local circumstances.   Not so matters of moral law. 
  
  The lay need to help the Church serve its mission and not simply be noisy spectators.
  
  From St Paul's letter to the Romans: 
  
  "May the God of endurance and encouragement grant you to think in harmony with one another, in keeping with Christ Jesus, that with ONE ACCORD you may with ONE VOICE glorify the God and Father of our Lord Jesus Christ."
