Pope John Paul II is the second longest serving pope in history and the longest serving pope of the last century. His presence has thrown a long shadow across our time, and his influence on Catholics and non-Catholics throughout the world cannot be denied. Much has been written about this pope, but until now, no one has provided a systematic and thorough analysis of the moral theology that underlies his moral teachings and its astonishing influence. And no one is better positioned to do this than Charles E. Curran, widely recognized as the leading American Catholic moral theologian. Brilliantly constructed and fearlessly argued, this will be the definitive measure of Pope John Paul II's moral theology for years to come.
