Legate
On 24 November 1302, Boniface VIII sent him to France as legate to Philippe le Bel. Philippe stood up to papal demands, and the Cardinal laid an interdict on the kingdom, requiring Nicolas de Fréauville, the king's confessor, to attend Rome with an explanation.
The pope modified the interdict to an excommunication of the king. Phillipe intercepted the messengers with the bull, at Troyes, and placed the legate Jean under surveillance. The king then called together the États Généraux (1303). The Cardinal left Paris by night, and returned to Rome.
