The Pater Noster is the greatest and most familiar prayer of the Church, taught to us by our Lord himself. Incessant repetition of a prayer is a very good and necessary thing, but if we are not careful, we may cease to ponder on it. There are many fine commentaries by St. John Chrysostom, St. Thomas, et alii, which bring out the spiritual riches. I am only a philologist, a student of languages, and will confine myself to elucidating the words. Some of what I have to say—and more—can be found in the podcasts we did on the subject.
