In the Introduction, Macy points to the past and asks some very pertinent questions:
For over fifteen hundred years, Christians were, for the most part, “in communion”. … The Christian people, as a whole, have a much longer history of unity than of disunity. This simple historical observation raises some interesting questions. How did we as a community get from there to here? How did the earlier centuries manage to maintain the communion which seems so to elude us? … Perhaps in rediscovering for overcoming our present disunion.
