In this book the author explores central questions in current ecclesiological and ecumenical debates from the perspective of an evangelical catholicity of 'the Great Tradition of the Church.' Tjrhom shows how the fundamental visibility of the Church and the similarity visible nature of Church fellowship is a corrective cover against 'invisible' perceptions of these entities. This theme of visibility is developed in view of the sacraments, the ministries, and the mission of the Church.
