The Greek emperors did not fail to profit by this favorable opportunity, and the patriarch himself in person celebrated the divine liturgy in the Church of St. Sophia with the utmost possible magnificence before the astonished ambassadors of Vladimir. The sublimity and splendor of the service struck them; but we do not ascribe to the mere external impression that softening of the hearts of these heathens, on which depended the conversion of a whole nation. From the very earliest times of the Church, extraordinary signs of God's power have constantly gone hand-in-hand with that apparent weakness of man by which the Gospel was preached; and so also the _Byzantine Chronicle_ relates of the Russian ambassadors, "That during the Divine liturgy, at the time of carrying the Holy Gifts in procession to the throne or altar and singing the cherubic hymn, the eyes of their spirits were opened, and they saw, as in an ecstasy, glittering youths who joined in singing the hymn of the 'Thrice Holy.'" Being thus fully persuaded of the truth of the orthodox faith, they returned to their own country already Christians in heart, and without saying a word before the Prince in favor of the other religions, they declared thus concerning the Greek: "When we stood in the temple we did not know where we were, for there is nothing else like it upon earth: there in truth God has his dwelling with men; and we can never forget the beauty we saw there. No one who has once tasted sweets will afterward take that which is bitter; nor can we now any longer abide in heathenism." Then the _boyars_ said to Vladimir: "If the religion of the Greeks had not been good, your grandmother Olga, who was the wisest of women, would not have embraced it." The weight of the name of Olga decided her grandson, and he said no more in answer than these words: "Where shall we be baptized?" But Vladimir, led by a sense which had not yet been purged by Greece, thought it best to follow the custom of his ancestors, who made warlike descents upon Constantinople, and so win to himself, sword in hand, his new religion. He embarked his warriors on board their vessels and attacked Cherson in the Taurid, a city which was subject to the emperors Basil and Constantine.
