Mark Noll -- University of Notre Dame "This book exemplifies the best in charitable yet tradition-specific ecumenical discussion. A. G. Roeber (a Lutheran become Orthodox), Mickey Mattox (a Lutheran become Catholic), and Paul Hinlicky (a Lutheran who remains Lutheran) explain what they find helpful (or indispensable) in Lutheran theology and then why they have transcended (or retained) those Lutheran insights. The result is both a primer in the classical Trinitarianism that the authors share and a set of powerful statements about the Orthodox, Catholic, and Lutheran distinctives that have remained to this point irreconcilable. Evangelical Protestants will especially appreciate the book's instruction in classical orthodoxies as well as its goad to probe the strengths and weaknesses of their own traditions with the care that these authors have shown toward theirs." Elpidophoros Lambriniadis -- Metropolitan of Bursa "An inspiring, intellectual illustration of the unique concepts and convictions, as well as the theological and cultural differences, in the creative interplay and interchange between Orthodox, Catholic, and Lutheran theologians." Risto Saarinen -- University of Helsinki"A bold and considerate book on a highly sensitive subject. In ecumenical theology, the issue of conversion has for the most part been discussed in anonymous and abstract terms. Mattox, Roeber, and Hinlicky offer a personal account that takes this deeply theological issue and the context of our contemporary world seriously." Richard J. Sklba -- Bishop Emeritus, Archdiocese of Milwaukee "With theological precision, frequent brilliance, and occasional brutal honesty regarding all three of the major ecclesial traditions examined in this work, these scholars explore the serious questions at issue if one moves from Lutheranism to Catholicism (Mattox) or to Orthodoxy (Roeber) or if one decides to remain within Lutheranism (Hinlicky). . . . This apologia is poised to make a substantial contribution to ecclesiology at the beginning of the twenty-first century."
