Henri de Lubac’s massive 3 volumes on medieval Christian biblical interpretation, Medieval Exegesis, remain classics in the field. You cannot study medieval biblical interpretation and safely ignore de Lubac’s volumes. Perhaps he overemphasized recourse to allegorical interpretation, and the Four-Fold Sense of Scripture, but he certainly brought needed attention to such interpretation, which was very important in the medieval period, and to medieval interpretation more broadly. For some reason, as of the writing of this post, all three volumes are available on Kindle for a mere $1.99 each!!! Volume 1 is available here. Volume 2 is available here. Volume 3 is available here.
