But grant that they were one and all opposed to it, it would not prove much. For, _first_, it could hardly happen otherwise, since the whole Protestant cause is so contained in this matter of the Primacy, that, were they to confess themselves wrong in it, they would pronounce themselves guilty of the most groundless schism. Therefore it is a matter of life and death with them to resist us. _Secondly_, as they dissent from us, so do they desert that doctrine which the whole Christian body solemnly professed and defined before the sixteenth century in ecumenical councils, that of Florence held in 1439, the second of Lyons in 1274, and the fourth Lateran in 1215. We, then, follow antiquity, and they take up novelty. And so it follows that while we have Protestants against us, we have the earlier Christians for us, whilst Protestants are opposed not only to the present race of Catholics, but to those whose children these are, and whose doctrines they have preserved. For as to the ancient interpretation of these texts take the following proof, contained in a letter of Pope Agatho to the Greek emperor Heraclius, read and approved in the sixth general council, A.D. 680. "The true confession of Peter was revealed by the Father from heaven, for which Peter was pronounced to be blessed by the Lord of all, who likewise by a triple commendation was entrusted with the feeding of the spiritual sheep of the Church by the Redeemer of all Himself; in virtue of whose assistance this his apostolical church hath never turned aside from the path of truth to any error whatsoever; whose authority, as of the Prince of all the Apostles, the whole Catholic Church at all times and the universal councils faithfully embracing, have in all respects followed, and all the venerable Fathers have entertained its apostolic doctrine; through which there have shone the most approved lights of the Church; which while the holy orthodox Fathers have venerated and followed, _heretics have pursued with false accusations, and calumnies inspired by hatred. This is the living tradition of Christ's Apostles, which His Church everywhere holds._"[23] We might imagine that Sir Thomas More had these words before his eyes when he answered Luther, "not only all that learned and holy men have collected to the point moves me to give willing obedience to that See, but especially what we have so often witnessed, that not only there never was an enemy to the Christian faith who did not at the same time declare war against that See, but also that there never has been one who professed himself an enemy of that See without shortly after declaring himself signally a capital foe and traitor of Christ and our religion. Another thing, too, has great weight with me, that if, in this manner, the faults of individuals are laid to the charge of their office, all authority will collapse, and the people will be without ruler, law, or order. And if this ever happens, as it seems likely
