"It is the peculiarity of progress for a thing to be developed in itself; and the peculiarity of change, for a thing to be altered from what it was into something else."
~ Vincent of Lerins, Saint, noting the essential difference between development and alteration of the deposit of faith, over 1,000 years before Protestantism radically altered the face of Christianity. (Commonitorium, I, 23; see P.L., L). (see "Science and the Church")
