7. And here, in order to strengthen Our teaching and Our exhortations, it is well to recall how, from the beginning of Christianity, all who have been renowned for holiness of life and sacred learning have given their deep and constant attention to Holy Scripture. If we consider the immediate disciples of the Apostles, St. Clement of Rome, St. Ignatius of Antioch, St. Polycarp - or the apologists, such as St. Justin and St. Irenaeus, we find that in their letters and their books, whether in defence of the Catholic Faith or in its commendation, they draw faith, strength, and unction from the Word of God. When there arose, in various Sees, Catechetical and Theological schools, of which the most celebrated were those of Alexandria and of Antioch, there was little taught in those schools but what was contained in the reading, the interpretation and the defence of the divine written word. From them came forth numbers of Fathers and writers whose laborious studies and admirable writings have justly merited for the three following centuries the appellation of the golden age of biblical exegesis. In the Eastern Church, the greatest name of all is Origen - a man remarkable alike for penetration of genius and for persevering labour; from whose numerous works and his great Hexapla almost all have drawn that came after him. Others who have widened the field of this science may also be named, as especially eminent; thus, Alexandria could boast of St. Clement and St. Cyril; Palestine, of Eusebius and the other St. Cyril; Cappadocia, of St. $asil the Great and the two St. Gregories. of Nazianzus and Nyssa; Antioch, of St. John Chrysostom, in whom the science of Scripture was rivalled by the splendour of his eloquence. In the Western Church there were many names as great: Tertullian, St. Cyprian, St. Hilary, St. Ambrose, St. Leo the Great, St. Gregory the Great; most famous of all, St. Augustine and St. Jerome, of whom the former was so marvellously acute in penetrating the sense of God's Word and so fertile in the use that he made of it for the promotion of the Catholic truth, and the latter has received from the Church, by reason of his pre-eminent knowledge of Scripture and his labours in promoting its use, the name of the "great Doctor."(²⁷) From this period down to the eleventh century, although Biblical studies did not flourish with the same vigour and the same fruitfulness as before, yet they did flourish, and principally by the instrumentality of the clergy. It was their care and solicitude that selected the best and most useful things that the ancients had left, arranged them in order, and published them with additions of their own - as did S. Isidore of Seville, Venerable Bede, and Alcuin, among the most prominent; it was they who illustrated the sacred pages with "glosses" or short commentaries, as we see in Walafrid Strabo and St. Anselm of Laon, or expended fresh labour in securing their integrity, as did St. Peter Damian and Blessed Lanfranc. In the twelfth century many took up with great success the allegorical exposition of Scripture. In this kind, St. Bernard is pre-eminent; and his writings, it may be said, are Scripture all through. With the age of the scholastics came fresh and welcome progress in the study of the Bible. That the scholastics were solicitous about the genuineness of the Latin version is evident from the Correctoria Biblica, or lists of emendations, which they have left. But they expended their labours and industry chiefly on interpretation and explanation. To them we owe the accurate and clear distinction, such as had not been given before, of the various senses of the sacred words; the assignment of the value of each "sense" in theology; the division of books into parts, and the summaries of the various parts; the investigation of the objects of the writers; the demonstration of the connection of sentence with sentence, and clause with clause; all of which is calculated to throw much light on the more obscure passages of the sacred volume. The valuable work of the scholastics in Holy Scripture is seen in their theological treatises and in their Scripture commentaries; and in this respect the greatest name among them all is St. Thomas of Aquin.
