Innocent visitors to an Episcopalian or Anglican church are often startled when the congregation blithely proclaim in the creed that they believe in “the holy Catholic Church.” Aren’t they supposed to be the other guys? But there are excellent reasons for that claim, and Matthew Barrett’s new backbreaking book, The Reformation as Renewal: Retrieving the One, Holy, Catholic, and Apostolic Church, is written to explain it. It is a claim that goes right to the heart of what the Protestant Reformation was and is.
