George was the seventh Byzantine church leader in Kievan Rus,[1] and he arrived to what is now Ukraine around 1062.[1] George did not recognize the sanctity of the local martyrs, and four years after his appointment he returned to Byzantium.[2]
Metropolitan George is credited as author of polemical work "Struggle against the Latina" (Stiazanie s latinoiu)[1][3] in relation to the 1054 East–West Schism.
