He was involved in the aftermath of the Paris disputation of 1240, and subsequent condemnation of the "Talmud". After the disputation a tribunal was appointed to pass judgment upon the Talmud, among its members being Eudes de Chateauroux, Chancellor of the University of Paris; Guillaume d'Auvergne, Bishop of Paris; and the Inquisitor Henri de Cologne. After the same rabbis had been heard a second time, the Talmud was condemned to be burned. Two years after (in the middle of 1242) twenty-four cartloads of Hebrew books were burned at Paris. [...] A little later, while at Lyons, the pope listened to the complaints of the Jews, and in 1247 he asked Eudes de Chateauroux to examine the Talmud from the Jewish standpoint, and to ascertain whether it might not be tolerated as harmless to the Christian faith, and whether the copies which had been confiscated might not be returned to their owners. The rabbis had represented to him that without the aid of the Talmud they could not understand the Bible or the rest of their statutes. Eudes informed the pope that the change of attitude involved in such a decision would be wrongly interpreted, and on 15 May 1248 the Talmud was condemned for the second time. A long list of supposed "errors and blasphemies" contained the Talmud was compiled by Eudes de Chateauroux. He was made cardinal-bishop of Frascati (1244). He is given also as bishop of Toulouse and bishop of Maguelonne and legate, and was sent to preach crusade in France by Pope Innocent IV. He accompanied Louis IX of France on the Seventh Crusade, and is mentioned by Joinville, returning in 1254, via Cyprus. Dean of the Sacred College of Cardinals from December 1254 and Camerlengo of the Holy Roman Church in 1270.
