The fourth is taken from the inequality of their jurisdictions. For if God, saith he, had given it them immediately, He had given as well equality of jurisdiction as of order; but we see, some are bishops but of one 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 less, as it pleaseth the Prince of the Church. Which argument, if he had proved before, that the Pope had an universal 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 emperors of Rome (for the patriarch of Constantinople, upon the same title, namely, of being bishop of the capital city of the empire, and seat of the emperor, claimed to be equal to him), it followeth, that all other bishops have their jurisdiction from the sovereigns 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 only where he is also the civil sovereign.
