St. Augustine of Canterbury – 

When Jesus prayed for togetherness he was not so concerned with our opinions as with our attitudes.  Remember what he said: “By this shall all know that you are my disciples in that you love one another.” I don’t have to agree with you on every issue and you don’t have to agree with me. There can be unity in our diversity if only we have love. How can our Lord’s plea for Christian unity ever be fulfilled without your help and mine? We have to pitch in and get that prayer answered.
