"Reason illumined by faith, when it inquires diligently, reverently, and judiciously, with God's help attains some understanding of the mysteries, and that a highly fruitful one, both from the analogy of what it naturally knows and from the interconnection of my mysteries with one another and with our last end. Yet reason never becomes capable of understanding the mysteries in the same way as it does truths that are its own proper object.

Therefore, let there be growth...and all possible progress in understanding, knowledge, and wisdom in single individuals and in all, in each person and in the entire church, according to the degree proper to each age and each time."
