"“This volume is a valuable, even a necessary, piece of the modern story of Christianity. I think such a marvelous work echoes some of the similar discerning outlook of Diarmaid MacCulloch’s splendid Christianity: The First Three Thousand Years.” —Michael Plekon, author of The World as Sacrament “The reader comes away with a clear and nuanced picture of the Old Catholic movement, a real appreciation for the depth of the ecumenical thinking it inspired, and a good grasp of interconfessional relations in the nineteenth century.” —Paul Valliere, author of Conciliarism ""This volume is readable and engaging, and it contains sufficient explanations to be accessible to the non-expert...a welcome contribution to the study of Christian history."" — Reading Religion ""Geffert and Boerneke reveal themselves to be trusted mentors who themselves treat their sources with respect, critical acumen, and perspicacious contextual awareness."" — Journal of Ecumenical Studies"
