1 They that are spectators of the heathen games, when they have learned that a distinguished athlete and winner of crowns has come from any quarter, run all together to view his wrestling, and all his skill and strength; and you may see the whole theater of many ten thousands, all there straining their eyes both of body and mind, that nothing of what is done may escape them. So again these same persons, if any admirable musician come among them, leave all that they had in hand, which often is necessary and pressing business, and mount the steps, and sit listening very attentively to the words and the accompaniments, and criticising the agreement of the two. This is what the many do.
Again; those who are skilled in rhetoric do just the same with respect to the sophists, for they too have their theaters, and their audience, and clappings of hands, and noise, and closest criticism of what is said.
And if in the case of rhetoricians, musicians, and athletes, people sit in the one case to look on, in the other to see at once and to listen with such earnest attention; what zeal, what earnestness ought you in reason to display, when it is no musician or debater who now comes forward to a trial of skill, but when a man is speaking from heaven, and utters a voice plainer than thunder? For he has pervaded the whole earth with the sound; and occupied and filled it, not by the loudness of the cry, but by moving his tongue with the grace of God.
And what is wonderful, this sound, great as it is, is neither a harsh nor an unpleasant one, but sweeter and more delightful than all harmony of music, and with more skill to soothe; and besides all this, most holy, and most awful, and full of mysteries so great, and bringing with it goods so great, that if men were exactly and with ready mind to receive and keep them, they could no longer be mere men nor remain upon the earth, but would take their stand above all the things of this life, and having adapted themselves to the condition of angels, would dwell on earth just as if it were heaven.
