Literat staroruski o kościołach katolickich: próba komentarza do „Georgija metropolity kijowskiego sporu z Łaciną”
Old Rusian homily entitled “Dispute Against Latins” and ascribed to metropolitan George of Kiev represents a tradition of polemic sermons against Western Christianity based on the writings of patriarchs Photios and Michael Cerularius, which appeared in the very time of Great Schism. In most part the “Dispute…” repeats the contents of byzantine polemic writings. However several additions were made taking into consideration the development of Church service and discipline in the 12th-13th centuries. Making of such an additions demonstrates that Rusian bookmen preserved a living interest in cultural differences between Eastern and Western Christianity and were capable of noting such differences in details. Such an information could be obtained due to personal contacts with Catholics or travels to Western Europe which was not uncommon for Rusians of the pre-Mongol time.
