7 Wherefore, to proceed, together with the punishment let me speak also of the shame. For as the Jews shall then be condemned by the Ninevites, so we too by many that seem beneath us now.
Let us imagine then how great the mockery, how great the condemnation; let us imagine, and cast some foundation at length, some door of repentance.
To myself I say these things, to myself first I give this advice, and let no one be angry, as though he were condemned. Let us enter upon the narrow way. How long shall it be luxury? How long sloth? Have we not had enough of indolence, mirth, procrastination? Will it not be the same over again, feasting, and surfeiting, and expense, and wealth, and acquisitions, and buildings? And what is the end? Death. What is the end? Ashes, and dust, and coffins, and worms.
Let us show forth then a new kind of life. Let us make earth, heaven; let us hereby show the Greeks, of how great blessings they are deprived. For when they behold in us good conversation, they will look upon the very face of the kingdom of Heaven. Yea, when they see us gentle, pure from wrath, from evil desire, from envy, from covetousness, rightly fulfilling all our other duties, they will say, “If the Christians have become angels here, what will they be after their departure hence? If where they are strangers they shine so bright, how great will they become when they shall have won their native land!” Thus they too will be reformed, and the word of godliness “will have free course,” not less than in the apostles' times. For if they, being twelve, converted entire cities and countries; were we all to become teachers by our careful conduct, imagine how high our cause will be exalted. For not even a dead man raised so powerfully attracts the Greek, as a person practising self-denial. At that indeed he will be amazed, but by this he will be profited. That is done, and is past away; but this abides, and is constant culture to his soul.
Let us take heed therefore to ourselves, that we may gain them also. I say nothing burdensome. I say not, do not marry. I say not, forsake cities, and withdraw yourself from public affairs; but being engaged in them, show virtue. Yea, and such as are busy in the midst of cities, I would fain have more approved than such as have occupied the mountains. Wherefore? Because great is the profit thence arising. “For no man lights a candle, and sets it under the bushel.” Therefore I would that all the candles were set upon the candlestick, that the light might wax great.
Let us kindle then His fire; let us cause them that are sitting in darkness to be delivered from their error. And tell me not, “I have a wife, and children belonging to me, and am master of a household, and cannot duly practise all this.” For though you had none of these, yet if you be careless, all is lost; though you are encompassed with all these, yet if you be earnest, you shall attain unto virtue. For there is but one thing that is wanted, the preparation of a generous mind; and neither age, nor poverty, nor wealth, nor reverse of fortune, nor anything else, will be able to impede you. Since in fact both old and young, and men having wives, and bringing up children, and working at crafts, and serving as soldiers, have duly performed all that is enjoined. For so Daniel was young, and Joseph a slave, and Aquila wrought at a craft, and the woman who sold purple was over a workshop, and another was the keeper of a prison, and another a centurion, as Cornelius; and another in ill health, as Timothy; and another a runaway, as Onesimus; but nothing proved an hindrance to any of these, but all were approved, both men and women, both young and old, both slaves and free, both soldiers and people.
Let us not then make vain pretexts, but let us provide a thoroughly good mind, and whatsoever we may be, we shall surely attain to virtue, and arrive at the good things to come; by the grace and love towards man of our Lord Jesus Christ, with whom be unto the Father, together with the Holy Ghost, glory, might, honor, now and ever, and world without end. Amen.
