" Pope Paul VI, addressing the members of the Congress on the Apostolate of the Laity on October 15, 1967, wishing to summarize what lay spirituality must be, stated: 'It will suffice to tell you in a word: only your personal and profound union with Christ will assure the fruitfulness of your apostolate, whatever it might be. "

― Father Jean C. J. D'Elbée
