10 Experience has truly proven that the annual meetings of Catholic men, in which under episcopal leadership common directives are discussed concerning Catholic affairs and the increase of pious activity, are wonderfully effective in strengthening unity and in arousing the zealous ingenuity of Catholics. We, therefore, ardently desire that these meetings be held. Nor do We have any doubt that they will greatly contribute to the success of your goals.
