In the U.S. on the First Sunday of Advent, November 27, 2011, we will implement the Third Edition of the Roman Missal. Unlike the revised liturgy of over forty years ago, we will not see any major changes to the way we celebrate Mass. What will be different is the translation, a slight rearrangement of the texts in the book itself, the addition of some new prefaces, new proper prayers for the saints that have recently been added to the church calendar. Most of this the average person in the pew won't even notice. What will be noticed is the people's responses. Just as we learned the English responses fairly quickly over four decades ago, we will no doubt do the same with these new texts now. Why this new Roman Missal? Why the new translation? What opportunities does this have for us to learn more about Mass and pray better? These and other such questions will be addressed in this course.
