"The greatest of all the mysteries of life, and the most terrible, is the corruption of even the sincerest religion, which is not daily founded on rational, effective, humble, and helpful action. Helpful action, observe! For there is just one law, (Mk. 12:30-31) which obeyed, keeps all religions pure, but forgotten, makes them all false. Whenever in any religious faith, dark or bright, we allow our minds to dwell upon the points in which we differ from other people, we are wrong, and in the devils power. 

That is the essence of the Pharisee's prayer - "Lord, I thank you that I am not as other men are."

At every moment of our lives we should be trying to find out, not in what we differ from other people, but in what we agree with them; and the moment we find we can agree as to anything that should be done, kind or good, then do it." John Ruskin.
