Shall I ask the brave soldier, who fights by my side
  In the cause of mankind, if our creeds agree?
    Shall I give up the friend I have valued and tried,
      If he kneel not before the same altar with me?
        From the heretic girl of my soul should I fly,
          To seek somewhere else a more orthodox kiss?
            No!  perish the hearts, and the laws that try
              Truth, valour, or love, by a standard like this!
