Early in his episcopate, Ralph entered into conflict with an archdeacon named Lambert and another canon, Arnulf, over the apportionment of revenues. Ralph accused them both of conspiring to kill him, removed them from their benefices and imprisoned them. William of Tyre contrasts Lambert, "a learned man of upright life with little or no experience in worldly affairs", with Arnulf, "learned and worldly-wise", who was a nobleman from
Calabria with connexions to the king of Sicily. After Raymond's marriage to Constance, he released the imprisoned priests. In the summer of 1138 he encouraged them to appeal to Rome and forced Ralph to go also and defend himself. When Ralph landed at
Brindisi, he was immediately arrested by men sent by King
Roger II of Sicily, and placed in the custody of Arnulf's family while awaiting a summons. In the end he was able to convince Roger that he was at odds with Raymond—Roger's real enemy—and allowed to go on to Rome. At Rome, Ralph received the
pallium from Innocent II. The consistory found the evidence insufficient to proceed and sent a legate to Antioch to resolve the dispute. On his return journey, Ralph visited the Sicilian court and was accompanied by a Sicilian fleet on his return to Antioch in the fall of 1138. Raymond refused him entry and he had to stay in one of the monasteries on the
Black Mountain outside Antioch. Joscelin of Edessa, who had started the riot in Antioch after Raymond and the emperor made peace, then invited Ralph to
Edessa, where he spent the winter of 1138–39. In the spring, Raymond invited Ralph back, and the latter returned accompanied by the three archbishops of the county of Edessa. The papal legate, the archbishop
Peter, arrived soon after, but on 25 May, before reaching Antioch, he died at
Acre. With the death of the legate and the victory of Roger II over Innocent II at the
battle of Mignano on 22 July the balance of power had swung in Ralph's favour. Lambert made his peace and was re-instated, but Arnulf returned to Rome to seek a new legate. In the fall, Innocent appointed
Alberic of Ostia to hear the case. ==Deposition==
