50 These mainly concern the exegetes, yet preachers, too, must always bear them in mind. Jerome's first rule is careful study of the actual words so that we may be perfectly certain what the writer really does say. He was most careful to consult the original text, to compare various versions, and, if he discovered any mistake in them, to explain it and thus make the text perfectly clear. The precise meaning, too, that attaches to particular words has to be worked out, for "when discussing Holy Scripture it is not words we want so much as the meaning of words." We do not for a moment deny that Jerome, in imitation of Latin and Greek doctors before him, leaned too much, especially at the outset, towards allegorical interpretations. But his love of the Bible, his unceasing toil in reading and re-reading it and weighing its meaning, compelled him to an ever-growing appreciation of its literal sense and to the 88 formulation of sound principles regarding it. These we set down here, for they provide a safe path for us all to follow in getting from the Sacred Books their full meaning. In the first place, then, we must study the literal or historical meaning: I earnestly warn the prudent reader not to pay attention to superstitious interpretations such as are given cut and dried according to some interpreter's fancy. He should study the beginning, middle, and end, and so form a connected idea of the whole of what he finds written.
