At the five-hundreth anniversary of Martin Luther's Ninety-Five Theses and the dawn of the Protestant movement, Indulgences: Luther, Catholicism, and the Imputation of Merit sets forth a revised theological interpretation of the Church's practice of indulgences. Author Mary C. Moorman argues that Luther's sola fide theology merely absolutized the very logic of indulgences which he sought to overthrow, while indulgences in their proper context remain an irreducible witness to the Church's corporate nuptial covenant with Christ, by which penitents are drawn into deeper fellowship with the Church and the Church's Lord. As Robert W. Shaffern, Professor of Medieval History at the University of Scranton, writes in his foreword to Indulgences, "Mary Moorman's book joins a number of recent scholarly studies that revise substantially the old convictions about indulgences. She is mostly interested in how theological thinking about indulgences should be done today, with of course the help that patristic, medieval, and early modern authorities might lend. She brings to bear a broad range of primary and secondary sources on the issue of indulgences and constructs an impressive series of covalent images with which to understand the role of indulgences in today's Christian Church."
