27 June 1299. The bull ordered Edward to desist his attacks and start negotiations with the Scots. However, Edward ignored the bull; in 1301, a letter was composed in which the English rejected its authority, but it was never sent. Continued feud with Philip IV The feud between Boniface and Philip IV reached its peak in the early 14th century, when Philip began to launch a strong anti-papal campaign against Boniface. A quarrel arose between Philip's aides and a papal legate, Bernard Saisset. The legate was arrested on a charge of inciting an insurrection, was tried and convicted by the royal court, and committed to the custody of the archbishop of Narbonne, Giles Aycelin – one of his key ministers and allies, in 1301. In the bull Ausculta Fili ("Listen, [My] Son", December 1301) Boniface VIII appealed to Philip IV to listen modestly to the Vicar of Christ as the spiritual monarch over all earthly kings. He protested against the trial of churchmen before Philip's royal courts and the continued use of church funds for state purposes and he announced he would summon the bishops and abbots of France to take measures "for the preservation of the liberties of the Church". When the bull was presented to Philip IV, Robert II, Count of Artois, reportedly snatched it from the hands of Boniface's emissary and flung it into the fire. In February 1302 the bull Ausculta Fili was officially burned at Paris before Philip IV and a great multitude. Nonetheless, on 4 March 1302, Pope Boniface sent cardinal Jean Lemoine as his legate to reassert papal control over the French clergy. To forestall the ecclesiastical council proposed by Boniface, Philip summoned the three estates of his realm to meet at Paris in April. At this first French Estates-General in history, all three classes – nobles, clergy, and commons – wrote separately to Rome in defense of the king and his temporal power. Some forty-five French prelates, despite Philip's prohibition, and the confiscation of their property, attended the council at Rome in October 1302. Following that council, on 18 November 1302, Boniface issued the bull Unam sanctam ("One holy [catholic and apostolic Church]"). It declared that both spiritual and temporal power were under the pope's jurisdiction, and that kings were subordinate to the power of the Roman pontiff. The Pope also appointed Cardinal Jean le Moine as Apostolic Legate to King Philip,
