This overview of WCC-RCC relations between 1999 and 2005 outlines discussion and collaboration in areas such as inter-religious dialogue, ecumenical formation, the Week of Prayer for Christian Unity, interchurch marriage, violence, refugees and migration, and diakonia and development. It includes three study documents: ecclesiological and ecumenical implications of a common baptism; the nature and purpose of ecumenical dialogue; and "Inspired by the same vision": RC participation in national and regional councils of churches.
