4. The increase of national prosperity and strength, to which the alienation of kings and states from the Holy See must be ascribed, in various ways indisposed them to the continuance of the war against the misbelievers. Rulers and people, who were increasing in wealth, did not like to spend their substance on objects both distant and spiritual. Wealth is a present good, and has a tendency to fix the mind on the visible and tangible, to the prejudice of both faith and secular policy. The rich and happy will not go to war, if they can help it; and trade, of course, does not care for the religious tenets of those who offer to enter into relations with it, whether of interchange or of purchase. Nor was this all; when nations began to know their own strength, they had a tendency to be jealous of each other, as well as to be indifferent to the interests of religion; and the two most valiant nations of Europe, France and England, gave up the Holy Wars, only to go to war one with another. As in the twelfth century, we read of Coeur de Lion in Palestine, and in the thirteenth, of St. Louis in Egypt, so in the fourteenth do we read the sad tale of Poitiers and Cressy, and in the fifteenth of Agincourt. People are apt to ask what good came of the prowess shown at Ascalon or Damietta; forgetting that they should rather ask themselves what good came of the conquests of our Edwards and Henries, of which they are so proud. If Richard's prowess ended in his imprisonment in Germany, and St. Louis died in Africa, yet there is another history which ends as ingloriously in the Maid of Orleans, and the expulsion of tyrants from a soil they had usurped. In vain did the Popes attempt to turn the restless destructiveness of the European commonwealth into a safer channel. In vain did the Legates of the Holy See interpose between Edward of England and the French king; in their very presence was a French town delivered over by the English conqueror to a three days' pillage.[61] In vain did one Pope take a vow of never-dying hostility to the Turks; in vain did another, close upon his end, repair to the fleet, that "he might, like Moses, raise his hands to God during the battle;"[62] Christian was to war with Christian, not with infidel.
