40 To return, however, to the question of the formation of Biblical students. We must lay the foundations in piety and humility of mind; only when we have done that does St. Jerome invite us to study the Bible. In the first place, he insists, in season and out, on daily reading of the text. "Provided," he says, "our bodies are not the slaves of sin, wisdom will come to us; but exercise your mind, feed it daily with Holy Scripture." And again: "We have got, then, to read Holy Scripture assiduously; we have got to meditate on the Law of God day and night so that, as expert money-changers, we may be able to detect false coin from true."
