40 Is it not because they have, with a zeal that is presumptive, set aside those traditional rules of discretion, modesty and prudence that certain priests consider as out of date and incompatible with "the present needs of the ministry those principles of discipline and conduct which they received from their masters in the senior seminary?" They are to be seen rushing, as if by instinct, into the most perilous innovations in speech, manners and associations. Several of them, alas! rashly putting themselves on the slippery incline from which they have no native power to escape, and despising the charitable warnings of their superiors and their older and more experienced colleagues, have ended in apostasies which rejoice the hearts of the adversaries of the Church and brought bitterest tears into the eyes of their Bishops, their brothers in the priesthood and the pious faithful. St. Augustine tells us: "When a man is out of the right way the more quickly and impetuously he advances, the more he errs."(31)
