It is a good recommendation for people wanting to learn about the Sacraments of Holy Church that they go to Dr. Scott Hahn, in either book form or (as above) in live address. Dr. Hahn was drawn toward the Catholic Faith through the Holy Mass, where he found the Scripture, that he loved and that he had studied for all his life, coming to life before his eyes. He describes this experience at the beginning of the video and it is important for long-time Catholics, for whom Mass sometimes becomes tedious and even a bore, to hear it and to rediscover what they have discounted through familiarity.
There's very little more to say really, for Dr. Hahn says it all. If you have an hour free at all on a sunny weekend, have a listen and rediscover the essence of the Catholic Faith.
