"Religion, after all (as everyone knows), is a realm of purely personal conviction sustained by faith, which is (as everyone also knows) an entirely irrational movement of the will, an indistinct impulse of saccharine sentiment, pathetic longing, childish credulity, and vague intuition. And theology, being the special language of religion, is by definition a collection of vacuous assertions, zealous exhortations, and beguiling fables; it is the peculiar patois of a private fixation or tribal allegiance, of interest perhaps to the psychopathologist or anthropologist, but of no greater scientific value than that; surely it has no proper field of study of its own, no real object to investigate, and whatever rules it obeys must be essentially arbitrary.

Now, as it happens, theology is actually a pitilessly demanding discipline concerning an immense, profoundly sophisticated legacy of hermeneutics, dialectics, and logic; it deals in minute detail with a vast variety of concrete historical data; over the centuries, it has incubated speculative systems of extraordinary rigor and intricacy, many of whose questions and methods continue to inform contemporary philosophy; and it does, when all is said and done, constitute the single intellectual, moral, spiritual, and cultural tradition uniting the classical, medieval, and early modern worlds. Even if one entirely avoids considering what metaphysical content one should attach to the word “God,” one can still plausibly argue that theology is no more lacking in a substantial field of inquiry than are history, philosophy, the study of literature, or any of the other genuinely respectable university disciplines.

Moreover, theology requires far greater scholarly range. The properly trained Christian theologian should be a proficient linguist, with a mastery of several ancient and modern tongues, should have formation in the subtleties of the whole Christian dogmatic tradition, should possess a considerable knowledge of the liturgies, texts, and arguments produced in every period of the Church, should be a good historian, should have a thorough philosophical training, should possess considerable knowledge of the fine arts, should have an intelligent interest in such areas as law or economics, and so on. This is not to say that one cannot practice theology without all these attainments, but such an education remains the scholarly ideal of the guild.”
