Laetitiae Sanctae §15

¹⁵ Here alone we discover the true relation between time and eternity, between our life on earth and our life in heaven; and it is thus alone that are formed strong and noble characters. When such characters can be counted in large numbers, the dignity and well-being of society are assured. All that is beautiful, good, and true will flourish in the measure of its conformity to Him who is of all beauty, goodness, and truth the first Principle and the Eternal Source.
