letter outlining the traditional Roman position against Monothelitism. Then in 716, Gregory received an official visit from Duke Theodo of Bavaria to discuss the continuing conversion of his lands to Christianity. As a result of this meeting, Gregory gave specific instructions to his delegates who were to travel to Bavaria, coordinate with the duke, and establish a local church hierarchy, overseen by an archbishop. Gregory maintained an interest in Bavaria; in 726 he forced an unwilling Corbinian, after reviewing his appeal through a synod, to abandon his monastic calling, and become bishop of Freising in upper Bavaria. Gregory next turned his attention to Germany. In 718, he was approached by an Anglo-Saxon missionary, Winfrid, who proposed undertaking missionary work in Germany. Gregory agreed, and after changing his name to Boniface, commissioned him in May 719 to preach in Germany. After hearing of the work that had been done so far, in 722 Gregory summoned Boniface back to Rome to answer rumors concerning Boniface’s doctrinal purity. At this face-to-face meeting, Boniface complained that he found Gregory’s Latin difficult to understand, a clear indication that Vulgar Latin had already started to evolve into the Romance languages. After examining Boniface’s written profession of faith, Gregory was satisfied enough that he made Boniface a bishop in November 722, and returned him to Germany to continue his mission. Continued successes saw Gregory write to Boniface in December 724 to offer his congratulations, followed in November 726 by a response to Boniface’s questions about how to structure the newly emergent churches in Germany. Gregory also strengthened papal authority in the churches of Britain and Ireland. In 726 Gregory was visited by Ine, the former King of Wessex, who had abdicated the throne in order to undertake a pilgrimage to Rome and end his life there. Local church activities Gregory also concerned himself with establishing or restoring monasteries. He turned his family mansion in Rome into a monastery, St. Agatha in Suburra, endowing it with expensive and precious vessels for use at the altar, and also established a new church, dedicated to Sant'Eustachio. In 718 he restored Monte Cassino, which had not recovered from an attack by the Lombards in 584, and he intervened in a dispute at the Monastery of St. Vincent on the Volturno over the deposition of the abbot. In 721, Gregory held a synod in Rome, for the purpose of fixing issues around
