From hence it followeth that one Church cannot be excommunicated by another: for either they have equal power to excommunicate each other, in which case excommunication is not discipline, nor an act of authority, but schism, and dissolution of charity; or one is so subordinate to the other, as that they both have but one voice; and then they be but one Church; and the part excommunicated is no more a Church, but a dissolute number of individual persons.
