“We speak then of the biblical theologian, and of biblical theology as that division of positive theology for which the materials are supplied by exegesis which is both scientific and guided by faith. But the very name of ‘biblical’ theology is somehow strange; it seems to be tautological. Any Christian of the Patristic period, of the Middle Ages, of the first millennium and a half of the Church’s history, would probably have inquired, ‘What other kind of theology is there?’ Certainly, St. Thomas would have been amazed at the suggestion that his Summa was somehow not biblical. As is plain the very first Questio, to him, sacra doctrina, sacra scriptura, and theologia were all—at least from his particular pedagogical point of view—one and the same thing. He aimed at systematizing and synthesizing, in easily intelligible form, the sum of revelation contained in the Word of God. And his magnificent accomplishment rests on a minute familiarity with the sacred text—in the Vulgate translation, naturally, and according to the exegetical science of his time.”
