AD 987 (6495): Vladimir (Prince of the Rus at Kiev) summoned together his vassals and the city elders, and said to them: “Behold, the Bulgars came before me urging me to accept their religion. Then came the Germans and praised their own faith; and after them came the Jews. Finally the Greeks appeared, criticizing all other faiths but commanding their own, and they spoke at length, telling the history of the whole world from its beginning. Their words were artful, and it was wondrous to listen and pleasant to hear them. They preach the existence of another world. ‘Whoever adopts our religion and then dies shall arise and live forever. But whosoever embraces another faith, shall be consumed with fire in the next world.’ What is your opinion on this subject, and what do you answer?” The vassals and the elders replied: “You know, O Prince, that no man condemns his own possessions, but praises them instead. If you desire to make certain, you have servants at your disposal. Send them to inquire about the ritual of each and how he worships God.” Their counsel pleased the prince and all the people, so that they chose good and wise men to the number of ten, and directed them to go first among the Bulgars and inspect their faith. The emissaries went their way, and when they arrived at their destination they beheld the disgraceful actions of the Bulgars and their worship in the mosque; then they returned to their own country. Vladimir then instructed them to go likewise among the Germans, and examine their faith, and finally to visit the Greeks. They thus went into Germany, and after viewing the German ceremonial, they proceeded to Constantinople where they appeared before the emperor. He inquired on what mission they had come, and they reported to him all that had occurred.. When the emperor heard their words, he rejoiced, and did them great honor on that very day.
On the morrow, the emperor sent a message to the patriarch to inform him that a Russian delegation had arrived to examine the Greek faith, and directed him to prepare the church and the clergy, and to array himself in his sacerdotal robes, so that the Russians might behold the glory of the God of the Greeks. When the patriarch received these commands, he bade the clergy assemble, and they performed the customary rites. They burned incense, and the choirs sang hymns. The emperor accompanied the Russians to the church, and placed them in a wide space, calling their attention to the beauty of the edifice, the chanting, and the offices of the archpriest and the ministry of the deacons, while he explained to them the worship of his God. The Russians were astonished, and in their wonder praised the Greek ceremonial. Then the Emperors Basil and Constantine invited the envoys to their presence, and said, “Go hence to your native country,” and thus dismissed them with valuable presents and great honor. Thus they returned to their own country, and the prince called together his vassals and the elders. Vladimir then announced the return of the envoys who had been sent out, and suggested that their
report be heard. He thus commanded them to speak out before his vassals. The envoys reported: “When we journeyed among the Bulgars, we beheld how they worship in their temple, called a mosque, while they stand ungirt. The Bulgarian 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. Then we went among the Germans, and saw them performing many ceremonies in their temples; but we beheld no glory there. Then we went on to Greece, and the 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. Every man, after tasting something sweet, is afterward unwilling to accept that which is bitter, and therefore we cannot dwell longer here.” Then the vassals spoke and said, “If the Greek faith were evil, it would not have been adopted by your grandmother Olga, who was wiser than all other men.” Vladimir then inquired when they should all accept baptism, and they replied that the decision rested with him.
