<p>The idea of <I>koinonia</I> has gained prominence in recent ecumenical discussions. Lorelei Fuchs proposes the theological concept of <I>koinonia</I>, loosely translated as communion, as the key to moving the fractured churches toward a future unity.</p> <p>Fuchs challenges churches to move beyond mere dialogue to apply their ecumenical insights at the local level. She begins by relating the exegetical meaning of <I>koinonia</I> to its ecumenical meaning, tracing the place of <I>koinonia</I> both within the churches and between the churches. She then examines the concept in the extensive and fruitful dialogues that have taken place between Lutherans, Anglicans, and Roman Catholics, finally articulating a symbolic competence for communionality that provides a rich and workable way forward for church unity at all levels.</p> <p>Encompassing the latest in ecumenical thought within the Catholic, Anglican, and Lutheran milieu, <I>Koinonia and the Quest for an Ecumenical Ecclesiology</I> provides a framework for moving closer to the reality of Christ's prayer that all may be one.</p>
