6 Who can credit the fact that one, who is the glory of the Furian stock and whose grandfathers and great grandfathers have been consuls, moves amid the senators in their purple clothed in sombre garb, and that, so far from blushing when he meets the eyes of his companions, he actually derides those who deride him! “There is a shame that leads to death and there is a shame that leads to life.” It is a monk's first virtue to despise the judgments of men and always to remember the apostle's words:— “If I yet pleased men, I should not be the servant of Christ.” In the same sense the Lord says to the prophets that He has made their face a brazen city and a stone of adamant and an iron pillar, to the end that they shall not be afraid of the insults of the people but shall by the sternness of their looks discompose the effrontery of those who sneered at them.
A finely strung mind is more readily overcome by contumely than by terror. And men whom no tortures can overawe are sometimes prevailed over by the fear of shame. Surely it is no small thing for a man of birth, eloquence, and wealth to avoid the company of the powerful in the streets, to mingle with the crowd, to cleave to the poor, to associate on equal terms with the untaught, to cease to be a leader and to become one of the people. The more he humbles himself, the more he is exalted.
