What does nihil constat de contingentia nisi ex revelatione mean?

"Nihil constat de contingentia nisi ex revelatione" is a Latin phrase that translates to "Nothing is known about contingency except through revelation." It suggests that our understanding of contingent truths—those that could be otherwise or are not necessary—can only be fully grasped through divine revelation or divine insight, rather than through human reasoning or empirical observation alone. This phrase emphasizes the limits of human knowledge regarding the nature of existence and the role of faith or revelation in understanding complex truths.
