Since God is the principal Author of Sacred Scripture, it can contain no error, no self-contradiction, nothing contrary to scientific or historical truth. The Encyclical “Providentissimus Deus” is most explicit in its statement of this prerogative of the Bible: “All the books which the Church receives as sacred and canonical, are written wholly and entirely, with all their parts, at the dictation of the Holy Ghost; and so far is it from being possible that any error can coexist with inspiration, that 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.” The Fathers agree with this teaching almost unanimously; we may refer the reader to St. Jerome (In Nah., I, iv), St. Irenæus (C. hær., II, xxviii), Clement of Alexandria (Stromata VII.16), St. Augustine (Reply to Faustus II.2; cf. “In Ps. cxviii”, serm. xxxi, 5; “Ad Hier.”, ep. lxxxii, 2, 22; “Ad Oros. c. Prisc.”, xi), St. Gregory the Great (Præf. in Job, n. 2). The great African Doctor suggests a simple and radical remedy against apparent errors in the Bible: “Either my codex is wrong, or the translator has blundered, or I do not understand.”
