In 1130 he was again appointed legate to Germany by Pope Innocent II, where he was instrumental in convincing Lothair III to make two expeditions to Italy for the purpose of protecting Pope Innocent II against the Antipope Anacletus II. He had a further period as legate to Germany in 1135–36. He was one of the principal negotiators with Lothair III in attempting to force the monks of Monte Cassino to submit themselves to the authority of the papacy. In addition, he was sent to Salerno to negotiate the end of the schism involving Anacletus II with King Roger II of Sicily. As a principal supporter of Pope Innocent II, the pope rewarded him for his efforts by appointing him papal chancellor. After the papal election of 1144, Gherardo was elected as Lucius II and consecrated on 12 March 1144. He probably took his name in honor of Pope Lucius I, who was commemorated a few days prior to Gherardo's consecration.
