There are several opinions regarding his tenure of office as a bishop. Radoslav M. Grujić states that he became Bishop of Prizren after the conquest of Polog in 1282. Đorđe Bubalo argues that he was ordained as the Bishop of Prizren after 1333 and before 1342. Janković suggests that he held his office until 1346. He and Markuš requested the gathered local noblemen and people at the Monastery of the Holy Virgin in Htětovo on 4th november of an unspecified year to swear to tell the truth concerning the disputed land located on the hill called Pleš (I zakle ih jepiskopь prizrěnьski Geōrgii Markušь vse starce i vlastele, i idoše na Plěšь na brьdo, da iznaidutь po svědočʼbě čija je Plěšь, ili jestь crьkevna ili Progonova). After the testimonies of witnesses confirmed the churchʼs possession of the hill Pleš, Geōrgi gave a speech to the present noblemen, where he declared himself as a real master of the local church estate (. I tako reče jepiskopь: boljare i horo, azь kьda prědrьžu crьkvu po izvoleniju božiju i gospodina mi arhiepiskopa da i tō i drugo ōtьkupiti hkju, gde nahogju crьkovno město, poneže jesmь sušti gospodarь i ōtьkupihь).
