Shortly after this, in September, 1293, Philippe went a step further and threw his ægis over the unfortunate Jew. Although Jews as a class were not liable to persecution by the Inquisition, still, if after being once converted they reverted to Judaism, or if they proselyted among Christians to obtain converts, or if they were themselves converts from Christianity, they were heretics in the eyes of the Church, they fell under inquisitorial jurisdiction, and were liable to be abandoned to the secular arm. All these classes were a source of endless trouble to the Church, especially the “neophytes” or converted Jews, for feigned conversions were frequent, either for worldly advantage or to escape the incessant persecution visited upon the unlucky children of Israel.[69] The bull _Turbato corde_, ordering the inquisitors to be active and vigilant in prosecuting all who were guilty of these offences, issued in 1268 by Clement IV., was reissued by successive popes with a pertinacity showing the importance attached to it, and when we see Frère Bertrand de la Roche, in 1274, officially described as inquisitor in Provence against heretics and wicked Christians who embrace Judaism, and Frère Guillaume d’Auxerre, in 1285, qualified as “Inquisitor of Heretics and Apostate Jews in France,” it is evident that these cases formed a large portion of inquisitorial business. As the Jews were peculiarly defenceless, this jurisdiction gave wide opportunity for abuse and extortion which was doubtless turned fully to account. Philippe owed them protection, for in 1291 he had deprived them of their own judges and ordered them to plead in the royal courts, and now he proceeded to protect them in the most emphatic manner. To Simon Brisetête, Seneschal of Carcassonne, he sent a copy of the bull _Turbato corde_, with instructions that while this was to be implicitly obeyed, no Jew was to be arrested for any cause not specified therein, and, if there was any doubt, the matter was to be referred to the royal council. He further enclosed an Ordonnance directing that no Jew in France was to be arrested on the requisition of any person or friar of any Order, no matter what his office might be, without notifying the seneschal or bailli, who was to decide whether the case was sufficiently clear to be acted upon without reference to the royal council. Simon Brisetête thereupon ordered all officials to defend the Jews, not to allow any exactions to be imposed on them whereby their ability to pay their taxes might be impaired, and not to arrest them at the mandate of any one without informing him of the cause. It would not have been easy to limit more skilfully the inquisitorial power to oppress a despised class.[70]
