The Church of God in Jesus Christ consists of three parts: the first provides a concise historical survey of ecclesiology elucidating the most salient teachings and insights from the Old and New Testaments, the writings of the fathers, the medievals, moderns, up to the present day. It integrates a standard historical overview with a recovery of oft ignored or forgotten insights from the tradition (e.g., beginnings of the Church in prehistoric times and in Israel, Irenaeus's Trinitarian ecclesiology and St. Bernard's nuptial vison of the Church. The second part is a systematic ecclesiology ordered around the four marks of the Church, then proceeding to treat the participation of all the faithful in the threefold office of Christ, the ongoing renewal and reform of the Church by the Holy Spirit working through her members, and finishing with a hitherto neglected study of the eschatological consummation of the Church in heavenly glory. The third part consists of five essays on particular themes of special importance in ecclesiology. Of the five, most notable is the chapter on the relationship between the Church's infallibility and Mary. Fr. Roch Kereszty intends to integrate theological insights with nourishing the reader's spiritual life by emphasizing the essentially Trinitarian, nuptial and Marian dimensions of the Church. The book fills a genuine need in that it offers a rich synthesis of the ecclesiological renewal in an accessible and clear language. It will enrich not only students of theology but all those college educated adults who are interested to delve beyond the clich s of the media into the contemplation of the manifold mystery of the Church.
