24 In seeking earthly riches, conveniences, and pleasures, in putting his trust in these, man pursues what escapes him, clings to what is crumbling down. For without God and His most holy law no right order is given man, no happiness worthy of the name, since man then lacks that solid basic norm by which to order his life; men in civil authority lack the basic norm for governing; and the community lacks the very foundation of moderation. And as you well know, Venerable Brothers, only heavenly joys, which are eternal, and not what is in flux and transitory, can fill and satisfy the soul.
