(as was the norm during the Byzantine Papacy). Controversy with Eutychius In Constantinople, Gregory took issue with the aged Patriarch Eutychius of Constantinople, who had recently published a treatise, now lost, on the General Resurrection. Eutychius maintained that the resurrected body "will be more subtle than air, and no longer palpable". Gregory opposed with the palpability of the risen Christ in Luke 24:39. As the dispute could not be settled, the Byzantine emperor, Tiberius II Constantine, undertook to arbitrate. He decided in favor of palpability and ordered Eutychius' book to be burned. Shortly after both Gregory and Eutychius became ill; Gregory recovered, but Eutychius died on 5 April 582, at age 70. On his deathbed Eutychius recanted impalpability and Gregory dropped the matter. Papacy Gregory was more inclined to remain retired into the monastic lifestyle of contemplation. In texts of all genres, especially those produced in his first year as pope, Gregory bemoaned the burden of office and mourned the loss of the undisturbed life of prayer he had once enjoyed as a monk. When he became pope in 590, among his first acts was writing a series of letters disavowing any ambition to the throne of Peter and praising the contemplative life of the monks. At that time, for various reasons, the Holy See had not exerted effective leadership in the West since the pontificate of Gelasius I. The episcopacy in Gaul was drawn from the great territorial families, and identified with them: the parochial horizon of Gregory's contemporary, Gregory of Tours, may be considered typical; in Visigothic Spain the bishops had little contact with Rome; in Italy the territories which had de facto fallen under the administration of the papacy were beset by the violent Lombard dukes and the rivalry of the Byzantines in the Exarchate of Ravenna and in the south. Pope Gregory had strong convictions on missions: "Almighty God places good men in authority that He may impart through them the gifts of His mercy to their subjects. And this we find to be the case with the British over whom you have been appointed to rule, that through the blessings bestowed on you the blessings of heaven might be bestowed on your people also." He is credited with re-energizing the Church's missionary work among the non-Christian peoples of northern Europe. He is most famous for sending a mission, often called the Gregorian mission, under Augustine
