At no time however, though he spoke so mildly and so candidly, acknowledging that the best way to overcome the heretics was to convert and to convince them, did Innocent conceal his intention and desire to carry proceedings against them to the sternest of conclusions. If it were possible by any exertions to bring them back to the bosom of the Church, he charged all ecclesiastical authorities, all preachers, priests, and monastic establishments to do everything that was possible to accomplish this great work; but failing that, he called upon all princes, lords, and civil rulers to take stringent measures and cut them off from the land--recommendations that ended in the tremendous and appalling expedient of a new Crusade, a Crusade with no double motive, no object of restoration and deliverance combined with that of destruction, but bound to the sole agency of sheer massacre, bloodshed, and ruin, an internecine warfare of the most horrible kind. It must be added, however, that the preachers who at Innocent's command set out, more or less in state, high officials, ecclesiastics of name and rank, to convince the heretics, by their preaching and teaching, took the first part in the conflict. According to his lights he spared no pains to give the doomed sects the opportunity of conversion, though with very little success. Among his envoys were two Spaniards, one a bishop, one that great Dominic, the founder of the Dominican order, who filled so great a part in the history of his time. Amid the ineffectual legates these two were missionaries born: they represented to the other preachers that demonstrations against heresy in the cathedrals was no way of reaching the people, but that the true evangelists must go forth into the country, humble and poor as were the adversaries whom they had to overcome. They themselves set out on their mission barefoot, without scrip or purse, after the manner of the Apostles. Strange to think that it was in Provence, the country of the Troubadours, the land of song, where poetry and love were supreme according to all and every tradition of history, that the grimmest heresy abounded, and that this stern pair carried on their mission! but so it was. Toulouse, where Courts of Love sate yearly, and the trouvères held their tournaments of song, was the centre of the tragedy. But not even those devoted preachers, nor the crowd of eager priests and monks who followed in their steps, succeeded in their mission. The priesthood and the religion it taught had fallen very low in Provence, and no one heeded the new missionaries, neither the heretics nor the heedless population around.
