Once again, we must return to the motto of the French Seminary in Rome that was so often on the lips of Archbishop Lefebvre and his mentor, Fr. LeFloch: "pietas cum doctrina, doctrina cum pietate" - "piety with doctrine, doctrine with piety." Novena books are usually heavy on piety and pretty short on doctrine, yet, as St. Thomas tells us, "you cannot love what you do not know." How can you love the Holy Ghost and communicate in prayer with Him, if you do not first know Him?
