"If Catholic and Protestant ethicians were asked to name a single theologian who was qualified to write a comprehensive overview of the historical divergences of Catholic and Protestant positions on ethical questions, the bases for those divergences in fundamentally different philosophical and theological perspectives, and the possibilities for future convergences of the traditions, my guess is that James Gustafson would be the one. This brilliant and tightly argued book . will be the most important book on moral theology to appear this year."-John Coleman, National Catholic Reporter.
