• Peace demands the most heroic labor and the most difficult sacrifice. It demands greater heroism than war. It demands greater fidelity to the truth and a much more perfect purity of conscience. — Thomas Merton (1915–1968) American Trappist monk
• The fact is that a man who wants to act virtuously in every way necessarily comes to grief among so many who are not virtuous. — Niccolo di Bernardo dei Machiavelli (1469-1527) Italian cynical philosopher
     Note: Jesus could see, and therefore show, the person aspiring to be virtuous what immaculate virtue looked like by living it every day to the end.

Comment: Although it would be impossible for an adult to honestly consider themselves to be immaculate, it is none-the-less a worthy ambition.
