1994 0-7734-9423-5 Through an analysis of the conciliar sources of the obligation of the Christian faithful to maintain communion with the Church, the revision of the previous law, and the process of articulating the obligation, this text uncovers the theological complexity and richness of a communion ecclesiology. From this basis, the text examines specific issues, including the function of the papacy, the common priesthood of the faithful, collegiality, dissent, the sacrament of marriage and the role of faith, and the question of Anglican orders.
