It has been said that the Bible is the best known but least understood book in literature. If so in the past, ignorance is no longer excusable. Today, extraordinary resources are available to make the Bible intelligible. During three decades of professional involvement with the Bible I have witnessed revolutionary developments in biblical studies, together with a phenomenal resurgence of interest in Scripture. Ecumenism has played a key role in this rebirth, especially for Roman Catholics, many of whom were biblically illiterate until they met Protestant and Jewish friends. John L. McKenzie’s trail-blazing book, The Two-Edged Sword (1956), also did much to awaken American Roman Catholic interest in the Bible, especially the Old Testament.
