In 1238 the Inquisition of Aragon may be said to be founded. In April of that year Gregory IX. wrote to the Franciscan Minister and Dominican Prior of Aragon deploring the spread of heresy through the whole kingdom, so that heretics no longer seek secrecy, but openly combat the Church, to the destruction of its liberties; and though this may be an exaggeration, we know from a confession before the Inquisition of Toulouse that there were enough scattered through the land to afford shelter to the wandering Catharan missionaries. Gregory, therefore, placed in the hands of the Mendicants the sword of the Word of God, which was not to be restrained from blood. They were instructed to make diligent inquisition against heresy and its abettors, proceeding in accordance with the statutes which he had issued, and calling in when necessary the aid of the secular arm. At the same time he made a similar provision for Navarre, which was likewise said to be swarming with heretics, by commissioning as inquisitors the Franciscan Guardian of Pamplona and the Dominican Pedro de Leodegaria. As an independent institution the Inquisition of Navarre seems never to have advanced beyond an embryonic condition. In 1246 we find Innocent IV. writing to the Franciscan Minister there to publish that Grimaldo de la Mota, a citizen of Pamplona, is not to be aspersed as a heretic because while in Lombardy he had eaten and drunk with suspected persons, but this is the only evidence of vitality that I have met with, and Navarre was subsequently incorporated into the Inquisition of Aragon.[188]
