For McBrien, the "broad term" refers exclusively and specifically to that "Communion of Catholic Churches" in communion with the Bishop of Rome. Richard McBrien, The Church: The Evolution of Catholicism (New York: HarperOne, 2008), 6, 281-82, and 356. In its Letter on Some Aspects of the Church Understood as Communion the Congregation for the Doctrine of the Faith stressed that the idea of the universal church as a communion of churches must not be presented as meaning that "every particular Church is a subject complete in itself, and that the universal church is the result of a reciprocal recognition on the part of the particular Churches". It insisted that "the universal Church cannot be conceived as the sum of the particular Churches, or as a federation of particular Churches".
