Such ardors cannot be permanent; they must subside, from the law of their nature. If the great Western mission had been a success, the enthusiasm of its founders might have maintained itself for some time longer; but that mission was extinguished in blood. Its martyrs died in vain, and the burning faith that had created it was rudely tried. Canada ceased to be a mission. The civil and military powers grew strong, and the Church no longer ruled with undivided sway. The times changed, and the men changed with them. It is a characteristic of the Jesuit Order, and one of the sources of its strength, that it chooses the workman for his work, studies the qualities of its members, and gives to each the task for which he is fitted best. When its aim was to convert savage hordes and build up another Paraguay in the Northern wilderness, it sent a Jogues, a Brebeuf, a Charles Garnier, and a Gabriel Lalemant, like a forlorn hope, to storm the stronghold of heathendom. In later times it sent other men to meet other needs and accomplish other purposes. Before the end of the seventeenth century the functions of the Canadian Jesuit had become as much political as religious; but if the fires of his apostolic zeal burned less high, his devotion to the Order in which he had merged his personality was as intense as before. While in constant friction with the civil and military powers, he tried to make himself necessary to them, and in good measure he succeeded. Nobody was so able to manage the Indian tribes and keep them in the interest of France. "Religion," says Charlevoix, "is the chief bond by which the savages are attached to us;" and it was the Jesuit above all others who was charged to keep this bond firm. The Christianity that was made to serve this useful end did not strike a deep root. While humanity is in the savage state, it can only be Christianized on the surface; and the convert of the Jesuits remained a savage still. They did not even try to civilize him. They taught him to repeat a catechism which he could not understand, and practise rites of which the spiritual significance was incomprehensible to him. He saw the symbols of his new faith in much the same light as the superstitions that had once enchained him. To his eyes the crucifix was a fetich of surpassing power, and the mass a beneficent "medicine," or occult influence, of supreme efficacy. Yet he would not forget his old rooted beliefs, and it needed the constant presence of the missionary to prevent him from returning to them.
