The document discusses the spread of Christian ideas in the Byzantine Empire and beyond in the 10th century. The Byzantine Church recognized the Emperor as representing Jesus Christ on earth and having authority over the patriarch. Disagreements arose between the Eastern Orthodox and Roman Catholic churches over icons and the authority of the Pope, resulting in each church excommunicating the other and a schism forming between the two branches of Christianity. Monasteries and convents were built near cities to spread Christian teachings through monks and nuns serving as examples through good deeds and lifestyle according to religious rules like the Basilian and Benedictine orders.
