"In our own times, you see, an emperor came to the city of Rome, where there's the temple of an emperor, where there's a fisherman's tomb. And so that pious and Christian emperor, wishing to beg for health, for salvation from the Lord, did not proceed to the temple of a proud emperor, but to the tomb of a fisherman, where he could imitate that fisherman in humility, so that he, being thus approached, might then obtain something from the Lord, which a haughty emperor would be quite unable to earn."
