3 Nor, with God's grace, were Our hopes entirely frustrated. Even those who are not Catholics, moved by the power of truth, avowed that the Church must be credited with a watchful care over all classes of society, and especially those whom fortune had least favored. Catholics, of course, profited abundantly by these letters, for they not only received encouragement and strength for the excellent undertakings in which they were engaged, but also obtained the light which they needed in order to study this order of problems with great sureness and success. Hence it happened that the differences of opinion which prevailed among them were either removed or lessened. In the order of action, much has been done in favor of the proletariat, especially in those places where poverty was at its worst. Many new institutions were set on foot, those which were already established were increased, and all reaped the benefit of a greater stability. Such are, for instance, the popular bureaus which supply information to the uneducated; the rural banks which make loans to small farmers; the societies for mutual help or relief; the unions of working men and other associations or institutions of the same kind. Thus, under the auspices of the Church, a measure of united action among Catholics was secured, as well as some planning in the setting up of agencies for the protection of the masses which, in fact, are as often oppressed by guile and exploitation of their necessities as by their own indigence and toil.
