In this volume five cardinals of the Church, and four other scholars, respond to the call issued by Walter Cardinal Kasper for the Church to harmonize "fidelity and mercy in its pastoral practice with civilly remarried, divorced people". The contributors are Walter Cardinal Brandmüller; Raymond Cardinal Burke; Carlo Cardinal Caffarra; Velasio Cardinal De Paolis, C.S.; Robert Dodaro, O.S.A.; Paul Mankowski, S.J.; Gerhard Cardinal Müller; John M. Rist; and Archbishop Cyril Vasil', S.J.
Cardinal Kasper appeals to early Church practice in order to support his view. The contributors bring their wealth of knowledge and expertise to bear upon this question, concluding that the Bible and the Church Fathers do not support the kind of "toleration" of civil marriages following divorce advocated by Cardinal Kasper. They also examine the Eastern Orthodox practice of oikonomia (understood as "mercy" implying "toleration") in cases of remarriage after divorce and in the context of the vexed question of Eucharistic Communion. The book traces the long history of Catholic resistance to this practice, revealing the serious theological and pastoral difficulties it poses in past and current Orthodox Church practice.
As the authors demonstrate, traditional Catholic doctrine, based on the teaching of Jesus himself, and current pastoral practice are not at odds with genuine mercy and compassion. The authentic "gospel of mercy" is available through a closer examination of the Church's teachings.
