ROMANO GUARDINI2025-07-151935-07-271935https://repository.act.ac.rw/handle/123456789/161AN old theological proverb says, "Nothing done by nature and grace is done in vain." Nature and grace obey their own laws, which are based upon certain established hypotheses. Both the natural and the supernatural life of the soul, when lived in accordance with these principles, remain healthy, develop, and are enriched. In isolated cases the rules may be waived without any danger, when such a course is required or excused by reason of a spiritual disturbance, imperative necessity, extraordinary occasion, important end in view, or the like. In the end, however, this cannot be done with impunity. Just as the life of the body droops and is stunted when the conditions of its growth are not observed, so it is with spiritual and religious life--it sickens, losing its vigor, strength and unity.enArticle
