3. The first and greatest care of Leo XIII was to set forth the teaching on the truth of the Sacred Books and to defend it from attack. Hence with grave words did he proclaim that there is no error whatsoever if the sacred writer, speaking of things of the physical order "went by what sensibly appeared" as the Angelic Doctor says, [5] speaking either "in figurative language, or in terms which were commonly used at the time, and which in many instances are in daily use at this day, even among the most eminent men of science." For "the sacred writers, or to speak more accurately — the words are St. Augustine's — [6] the Holy Spirit, Who spoke by them, did not intend to teach men these things — that is the essential nature of the things of the universe — things in no way profitable to salvation"; which principle "will apply to cognate sciences, and especially to history," [7] that is, by refuting, "in a somewhat similar way the fallacies of the adversaries and defending the historical truth of Sacred Scripture from their attacks." [8] Nor is the sacred writer to be taxed with error, if "copyists have made mistakes in the text of the Bible," or, "if the real meaning of a passage remains ambiguous." Finally it is absolutely wrong and forbidden "either to narrow inspiration to certain passages of Holy Scripture, or to admit that the sacred writer has erred," since divine inspiration "not only is essentially incompatible with error but excludes and rejects it as absolutely and necessarily as it is impossible that God Himself, the supreme Truth, can utter that which is not true. This is the ancient and constant faith of the Church." [9]

4. This teaching, which Our Predecessor Leo XIII set forth with such solemnity, We also proclaim with Our authority and We urge all to adhere to it religiously.

But first it must be clearly understood whom we have to oppose and contend against, and what are their tactics and their arms. In earlier times the contest was chiefly with those who, relying on private judgment and repudiating the divine traditions and teaching office of the Church, held the Scriptures to be the one source of revelation and the final appeal in matters of Faith. Now, we have to meet the Rationalists, true children and inheritors of the older heretics , who, trusting in their turn to their own way of thinking, have rejected even the scraps and remnants of Christian belief which had been handed down to them. They deny that there is any such thing as revelation or inspiration, or Holy Scripture at all; they see, instead, only the forgeries and the falsehoods of men; they set down the Scripture narratives as stupid fables and lying stories: the prophecies and the oracles of God are to them either predictions made up after the event or forecasts formed by the light of nature; the miracles and the wonders of God's power are not what they are said to be, but the startling effects of natural law, or else mere tricks and myths; and the Apostolic Gospels and writings are not the work of the Apostles at all. These detestable errors, whereby they think they destroy the truth of the divine Books, are obtruded on the world as the peremptory pronouncements of a certain newly-invented "free science;" a science, however, which is so far from final that they are perpetually modifying and supplementing it. And there are some of them who, notwithstanding their impious opinions and utterances about God, and Christ, the Gospels and the rest of Holy Scripture, would fain be considered both theologians and Christians and men of the Gospel, and who attempt to disguise by such honorable names their rashness and their pride. To them we must add not a few professors of other sciences who approve their views and give them assistance, and are urged to attack the Bible by a similar intolerance of revelation.
