Deepening Communion addresses the nature of the unity that God invites us to make visible to those around us. It pursues the role that ecumenical theoligical dialogue has in drawing people together in order to achieve more faithful, credible, and effective Christian witness. Building on Pope John Paul II's encyclical That They May Be One (Ut Umun Sint) and designed for use in ecumenical study locally and nationally, this collection of documents explores the growing relationship of the Catholic Church with the Lutheran, Reformed, Christian Church/Disciples of Christ, Baptist, and Pentecostal churches.
