20 Such were the reasons for which the Saint determined to institute the brotherhood of the Third Order, which was to admit all ranks, all ages, both sexes, and yet in no way necessitate the rupture of family or social ties. For its rules consist only in obedience to God and His Church, to avoid factions and quarrels, and in no way to defraud our neighbour; to take up arms only for the defence of religion and of one's country; to be moderate in food and in clothing, to shun luxury, and to abstain from the dangerous seductions of dances and plays.
