King Don Manuel was pursuing the Moors through the Red Sea and neighboring regions. He added that if this were not remedied, by ordering the said princes to desist from persecuting the Mahometans, he would destroy the holy house at Jerusalem and the sepulcher of the Redeemer. As can be verified, the letter contains many profane remarks against Christianity. It was sent by a Franciscan friar who lived in a monastery on the mount called Sion, and who was guardian there at Jerusalem. The said pontiff, as soon as he saw the letter, sent a copy of it to Castilla and Portugal through the same friar. King Don Manuel, your Majesty's grandfather, sent the celebrated answer to the pontiff, saying that he gave advice neither to the Apostolic See nor to the sacred council of cardinals; but what he answered (and he would do it with all his might) was to persecute Mahometans forever. He added that the Holy Father was much to blame for the sultan's pride, since he did not gather and unite in peaceful alliance the Christian princes, who were divided by wars in their own interests, and were neglecting so common an interest as that of undoing the power of Moors and Turks. He also answered that he understood his father and father-in-law, the Catholic king Don Fernando, to give the same answer. As I have said before, the histories of Portugal are full of these old enmities. It seems as if this evil sect had increased and multiplied in the West as well as in the islands and countries of the East. Indeed the various causes for this are to be found in the condition of these regions and in the measures, decrees, or instructions like those issued for Peru, Nueva España, and the other Yndias.
