Why is it that churches agree to the same basic faith in hundreds of dialogues, and yet remain locked in an "ecumenical winter"? In Choose the Narrow Path, Bishop Pierre Whalon argues that to acknowledge the same doctrines while acting as if churches should remain separate is not only a recipe for disaster, but it is also itself a sin. This book spells out that doctrinal agreement in Part I, while Part II uncovers a more personal reaction, structured around the Nicene Creed.
The primary argument is that, while churches may be "one," "holy," and "catholic" in what they believe, none of them is truly "apostolic" in their action. To begin to address this failing, the author calls for exceptional intercommunion for members of all churches that subscribe to the Narrow Path but are still reluctant to walk it together.
