Although when then-Fr. Joseph Ratzinger authored his 1968 Introduction to Christianity he was still four years away from founding the international journal Communio together with Henri de Lubac, Hans Urs von Balthasar, and others, the work clearly manifests the thought of the Communio school. In at least one respect, Ratzinger even seems to go further, at least in emphasis, than de Lubac’s ressourcement of the view that the human person has a natural desire for the vision of God. On the one hand, de Lubac insists that this desire coexists with the incommensurability of the orders of nature and grace, posits the existence of a distance between nature and the supernatural as radical as that between non-being and being, and argues that this desire is an “unknown desire” until God’s offer of the beatific vision is revealed. On the other hand, Ratzinger’s book seems to relate belief in the created logos more closely to faith in the creative Logos, and even writes that “in the last analysis one cannot make a neat distinction between ‘natural’ and ‘supernatural’: the basic dialogue that first makes man into man makes a smooth transition into the dialogue of grace known as Jesus Christ.”
Ratzinger’s text might indeed be considered an especially important product of that school. First, because it treats in one volume all of the articles of the Apostles’ Creed. Second, because of the importance of the Communio school’s ressourcement-approach to the formulation and interpretation of Catholic doctrine from Vatican II (i.e., the theological anthropology of Gaudium et Spes §22) to Pope St. John Paul II (i.e., the further treatment of this theological anthropology in Redemptor Hominis §10)—and beyond. Third, and in connection with the previous point, it is likewise relevant that Ratzinger is the future Pope Benedict XVI, who, in his last months as successor to St. Peter reflected on the dynamism of human desire that, without bringing about faith in God, nevertheless constitutes a desire for God and teaches that “The desire to know God truly, that is, to see God’s face, is innate in every human being.” Not only did Pope Benedict’s continue using Communio approaches, but he continues to have the highest regard for his colleagues from that movement. When he was asked by interviewer Peter Seewald, “Which theologians do you actually appreciate the most?,” Benedict responds, “I would still say Lubac and Balthasar.”
In light of the above, it seems reasonable to regard Ratzinger’s text as among the most significant works of 20th century Catholic theology, and as destined to enjoy the status of a classic. There are inescapably some elements of the work that could be seen as somewhat anachronistic: Ratzinger’s interaction (both appreciative and critical: “in spite of a not entirely unobjectionable tendency toward the biological approach”) with the thought of Pierre Teilhard de Chardin comes to mind. On the other hand, it seems at least possible that the main point of this interaction is to give himself another way to make his own points about, for example, the meaning of the biblical references to Jesus as “Adam.” Compare Ratzinger’s invocation of wave-particle duality, not unlikely a more enduring scientific concept, but, again, used by Ratzinger less for the sake of interacting with contemporary physics than in order to make a point about Trinitarian doctrine.
Because Ratzinger’s Introduction to Christianity comprises theological reflections on the articles of the Creed, and because of the substantive and historical importance of those theological reflections, one might wish to use the text in an introductory Catholic theology course. However, because of the complexity of some of these reflections, one might fear trying to teach the text to students at the undergraduate introductory level. As a Scholastic might note, “Introduction” may be meant in multiple ways; for example, there is Aquinas’s [in?]famous description of his Summa Theologiae as for “beginners” [incipientium].)
I am primarily a moral theologian. For the first several years of my full-time teaching career, I taught moral theology courses almost exclusively. Eventually, though, I needed to help cover sections of our Theology 101 course. Since then I have taught it every fall and sometimes in the spring. We use the Catechism of the Catholic Church in all sections of this course, along with such other readings as each faculty member may wish to assign in their sections. I believe it was before my first time preparing to teach the course that I learned that, although a handful of colleagues had tried to teach Ratzinger’s Introduction in Theology 101, all but one had at some point given up (one had not only given up, but had left for a position elsewhere!).
I had read the book several times over the years, and I understood their perspective. At the same time, I wanted to include the book in my sections of the course. I was going to use the Catechism—most especially all of Part One, which covers the Creed—as well as portions of its other three parts. During the two months that the students would be reading the Catechism, I was going to lecture, primarily on key eras in the history of some of the doctrines covered in the Catechism (for example, the Trinitarian and Christological controversies of the Patristic era and most especially of the fourth–sixth centuries). Thus, during two-thirds of the semester, the students would learn about the Creed in two complementary ways. I wanted to spend the remaining month on Ratzinger, whose reflections would take the students through the Creed in one additional way.
But how to do so, so that the students would learn from the text, challenging as it is, and would not mutiny? The book is 359 pages long, which makes for 90 pages a week, or 30 per day in a class that meets three times a week—not too unreasonably long, or in any case not out of step with the amount of reading I often assign in my classes. Usually I give my undergraduate classes weekly quizzes on readings, and in my introductory moral theology class I give two tests on the lecture material.
I decided quickly that I would not give my 101 class weekly quizzes on Ratzinger. I did not want students new to theology to feel that kind of pressure while reading the text. I also decided that I would not lecture on the book as they were reading it—I wanted them to learn directly from Ratzinger rather than from my condensations of his thoughts. Instead, their reading of it, and whatever went on in the classroom during that month, would combine to help them to understand it for themselves. And to take the pressure of their efforts to do so, I would not test them on it either.
I came up with the following plan:
- The daily reading assignments would be accompanied by a study question for each chapter section or subsection. These would be brief and would get at the heart of the material—typically, by being keyed to section titles. For example, the question on the first subsection of the book’s “Introduction” (really, an unnumbered “part,” along with parts one through three)—entitled “Doubt and belief—Man’s situation before the question of God”—would be: “What is man’s situation before the question of God”? The next subsection is “The origin of belief—Provisional attempt at a definition of belief”; its accompanying question was: “What is belief, and how can it be attained?” (Ratzinger speaks especially of the need for a certain kind of conversion that is needed in order for belief to happen).
- At the beginning of each class period, the students turned in their written answers to that day’s study questions. They would also be required to bring a second copy of that day’s answers, to refer to during discussion. I would break the class up into small groups—depending on class size and on number of questions for the day, as many groups as would allow me to give each group a small number of questions to discuss. In these small-group discussions, they would be expected to compare and to refine their individual answers. There would be enough time for these group discussions—say, 15 or 20 minutes—to allow for meaningful conversation. If one or more groups needed a little more time on a given day, I would allow that additional time. If at some point before the allotted time had passed all groups appeared done, and if I asked the class and determined that in fact they were all done, then I would end the discussion time. I would tell the class each day that, while the discussions were taking place, if any group found itself lost, then someone from that group should raise their hand; I would keep an eye out for any such distress signals, and if there were one, I would go to that group and help (without doing their work for them). I would also circulate around the room and listen in to the nearest group’s discussion and offer to help if a group seemed (perhaps without knowing it) to be lost. During the remainder of the period, after the small-group discussions, one member of each group (chosen by the group) would report that group’s consensus answers to the whole class. Other members of the class would then have the opportunity to add a few words to each answer; I would do so also, if and when it seemed good to me.
- From each week’s answers, I would usually select one set to be graded. (In a class meeting two or three times a week, I would grade one day’s questions; in classes meeting once a week, I would break the assigned questions into three sets and grade one of these.) I would do so with a fairly light touch. Did the student make a reasonable, and somewhat successful, attempt at answering by (in accordance with my instructions) summarizing and paraphrasing Ratzinger—rather than, say, simply pulling out a (sometimes semi-random) sentence or two from the text? Was the answer a few sentences long—neither so brief as to constitute a significantly incomplete answer, nor so long as to throw in a lot of clearly irrelevant material (in the hope that the real answer would be in there somewhere and that I would find it—what a teacher of mine, years ago, called a “kitchen sink” answer)? Each question set would be graded on a scale of zero to ten—just as each weekly true/false quiz during the earlier part of the semester would be a ten-question quiz yielding up to ten points. A student’s question points earned would, at semester’s end, be added to his or her quiz points earned (usually there are six quizzes and four graded sets of questions, making for 100 possible points, typically 60 from quizzes and 40 from study questions), and the resulting sum would constitute 25% of the student’s course grade—as would each of the two tests given on the lecture material during the earlier part of the semester, and as would the end-of-semester reflection paper, as described next:
- At semester’s end, a couple of days after the last class period, each student would turn in a reflection paper, just two or three pages long, on the book. In this paper, the student would state very briefly two points in the book (not both from the same “part” of the book) that they found somehow relevant to something very concrete and specific in their life—past, present, and/or planned for the future. The remainder of the paper—at least one and a half pages—would be spent reflecting on how each point was relevant to the student’s life. Simply or mostly repeating or explaining what Ratzinger says would not earn an A grade. I would be looking, as I would instruct the students both in writing (on the syllabus) and out loud (more than once in class), for personal reflection on the book’s relevance. I would not be looking for “right” or “wrong” answers, as long as the paper did not greatly misstate the chosen points for reflection from the book—I would be looking, almost entirely, for simply several paragraphs of genuinely thoughtful reflection, in some substantial way related to each the two points from the book. (I would also tell the students that if in order to carry out the assigned reflection they wish to reveal anything really “personal” to me, I will treat it as if under the seal of the confessional.) If I saw that the student was engaging in thoughtful reflection (and if the paper were well written), the student would receive an A.
I have now taught Theology 101 numerous times, working through Ratzinger’s Introduction to Christianity with each class, as described—study questions to be completed before each period by each student (there has been some evolution of the questions over the years), small-group then whole-class discussions of the answers, reflection paper. I think that what started out as an experiment has been successful.
Typically, most of the answers that I collect are good. Class discussions, sometimes with a bit of help from me (asking whether any of the students can add to what is initially said), are fruitful; there is enough time for group discussion and then some class discussion, and usually I do not find myself having much to add (as distinct from asking students to add) to what the discussions yield. Almost all of the students do a very fine job in the reflection papers, relating the book to their lives, and sometimes to very “personal” aspects of their lives.
There is no one way in which to teach an undergraduate introduction to Catholicism and to theology. There are some ways of doing so that I would not recommend; for example, using material that is too simple, or too complex—or that presents the “diversity” of “Catholic thought” at the expense of honesty about what the Church has taught and teaches and about the reasons for respecting this teaching.
But for those faculty who would like to try to use Ratzinger’s Introduction to Christianity—perhaps after a more basic tour though most or all of the articles through the Creed, through reading and/or lecture—I recommend doing so. It is not “too complex,” at least when used as I use it. It combines both fidelity to Scripture and Tradition and some of the best recent theological reflection (arising out of the Communio school). And, in my experience, when taught in the right way (I do not claim that my own is the only right way, just a successful one!), it is not too advanced for students at the undergraduate introductory level.
This is shown by students’ performance on assignments and in the classroom; moreover, students themselves seem to recognize that they are learning from the book. Typically, when asked directly after they have begun reading and discussing it whether they feel that they are learning, they answer that they do. Occasionally, a student will tell me that he or she talked with a sibling or friend studying theology at the post-baccalaureate level who was impressed that my student was reading the book at the introductory level. Typically, my student’s response will be one of justified pride for having made it through, and learned something from, the book.
Would I, at some point in the future, consider a different way of teaching the text, involving quizzes, lectures, or a test? No. But walking together through the book—as I describe my approach to each semester’s students—is a fruitful and successful way of enabling the students to complete an introductory course on Catholic theology, that is, so that they will take away from that course some sense of how the best of recent theology provides insights into the articles of the Creed, which is valuable both in itself, and insofar as it might give them a sense of the value of further study of Catholic theology.
