This book is composed of a series of essays carrying on the task of ecumenical discussion. Hutter is well read in both Lutheran and Roman Catholic traditions. He brings the two into dialogue throughout the book. It is divided into 3 sections. The first addresses what it means to be the church, particularly with the Catholic/Protestant divide. The second gives an account of what Christian freedom is in light of the law and gospel. Freedom is said to be the ability to live toward an end, participation in the life of the Triune God. The final section advances ecumenical dialogue through a reading of several Catholic documents. Though the language is difficult and the arguments rigorous, I believe the reward is worth the challenge. This book is for anyone who longs for unity in the church.
