In which he recounts:
The ancient Slavic chronicles record a famous episode that, when investigating which religion he and his people ought to embrace, Vladimir judged Islam altogether undesirable because of the prohibition on drinking alcohol, saying “Drinking is the joy of all Rus’. We cannot exist without that pleasure.” The envoys sent by him to visit the temples of various neighboring peoples reported that the Bulgar Muslim “bows, sits down, looks hither and thither like one possessed, and there is no happiness among them, but instead only sorrow and a dreadful stench. Their religion is not good.” Their report of the Latin Rite among the Germans was that “we beheld no glory there.” But they described the Divine Liturgy celebrated on a great feast in Constantinople in these terms: “(T)he Greeks led us to the edifices where they worship their God, and we knew not whether we were in heaven or on earth. For on earth there is no such splendor or such beauty, and we are at a loss how to describe it. We know only that God dwells there among men, and their service is fairer than the ceremonies of other nations. For we cannot forget that beauty… If the Greek faith were evil, it would not have been adopted by your grandmother Olga, who was wiser than all other men.”
Attention, Latin traditionalists: the Byzantine rite, not the Roman.
