For a Catholic understanding of the faith there is no reason why the basic concern of Evangelical Christianity as it comes to expression in the three “only's” should have no place in the Catholic Church. Accepted as basic and ultimate formulas of Christianity, they do not have to lead a person out of the Catholic Church. . . . They can call the attention of the Catholic church again and again to the fact that grace alone and faith alone really are what saves, and that with all our maneuvering through the history of dogma and the teaching office, we Catholic Christians must find our way back to the sources again and again, back to the primary origins of Holy Scripture and all the more so of the Holy Spirit.
