'We live in an age of bi-lateral conversations between Anglicanism and other Christian Churches. The 1988 Lambeth Conference affirmed those already established, and added to their number. It is a paradoxical truth of ecumenical experience to find that inter-church conversations have prompted many Anglicans to consider more deeply their own identity and traditions. This volume by Paul Avis will assist all those who do so. I welcome its appearance - a further sign that study of Anglican ecclesiology is firmly on our doctrinal agenda.' Robert Runcie '... written with outstanding facility and is a pleasure to read... a very important piece of work.' Stephen Sykes '... an excellent study I recommend with enthusiasm...' George Newlands '... very good, clear, sound exposition, original ideas...' Basil Hall
