Catholic Books Review "An excellent scholarly overview of convergences between Lutheran and Catholic theologians and some promising developments between the churches." William G. Rusch — Yale Divinity School "This work is an indispensable resource for anyone interested in overcoming the disunity of the churches. It demonstrates how high-quality scholarship can enlighten questions about the papacy that at first glance appear closed. Disclosing the potential for degrees of resolution to what were once regarded as intractable barriers to greater unity, this report cannot be recommended too highly." John A. Radano — Seton Hall University "A significant contribution to promoting ecumenical advance, this book is a must-read for those interested in the work of reconciliation among divided Christians."
