And for the following words, “I will give thee the keys of heaven,” etc. , it is no more than what our Saviour gave also to all the rest of His disciples ( Matt. 18:18), “Whatsoever ye shall bind on earth, shall be bound in heaven: and whatsoever ye shall loose on earth, shall be loosed in heaven.” But howsoever this be interpreted, there is no doubt but the power here granted belongs to all supreme pastors; such as are all Christian civil sovereigns in their own dominions. Insomuch, as if St. Peter, or our Saviour himself, had converted any of them to believe Him, and to acknowledge His kingdom; yet, because His kingdom is not of this world, He had left the supreme care of converting His subjects to none but him; or else He must have deprived him of the sovereignty, to which the right of teaching is inseparably annexed. And thus much in refutation of his first book, wherein he would prove St. Peter to have been the monarch universal of the Church, that is to say, of all the Christians in the world.
