The third, is, from that the Sea of S. Peter is called by S. Cyprian, the Head, the Source, the Roote, the Sun, from whence the Authority of Bishops is derived. But by the Law of Nature (which is a better Principle of Right and Wrong, than the word of any Doctor that is but a man) the Civill Soveraign in every Common-wealth, is the Head, the Source, the Root, and the Sun, from which all Jurisdiction is derived. And therefore, the Jurisdiction of Bishops, is derived from the Civill Soveraign. The fourth, is taken from the Inequality of their Jurisdictions: For if God (saith he) had given it them immediately, he had given aswell Equality of Jurisdiction, as of Order: But wee see, some are Bishops but of own Town, some of a hundred Towns, and some of many whole Provinces; which differences were not determined by the command of God; their Jurisdiction therefore is not of God, but of Man; and one has a greater, another a lesse, as it pleaseth the Prince of the Church. Which argument, if he had proved before, that the Pope had had an Universall Jurisdiction over all Christians, had been for his purpose. But seeing that hath not been proved, and that it is notoriously known, the large Jurisdiction of the Pope was given him by those that had it, that is, by the Emperours of Rome, (for the Patriarch of Constantinople, upon the same title, namely, of being Bishop of the Capitall City of the Empire, and Seat of the Emperour, claimed to be equal to him,) it followeth, that all other Bishops have their Jurisdiction from the Soveraigns of the place wherein they exercise the same: And as for that cause they have not their Authority De Jure Divino; so neither hath the Pope his De Jure Divino, except onely where hee is also the Civill Soveraign.
