1 Timothy 4:8

And, indeed, the old Hebrew wanderers in the desert received typically the end of the threatening; for they are said not to have entered into the rest, because of unbelief, till, having followed the successor of Moses, they learned by experience, though late, that they could not be saved otherwise than by believing on Jesus. But the Lord, in His love to man, invites all men to the knowledge of the truth, and for this end sends the Paraclete. What, then, is this knowledge? Godliness; and “godliness,” according to Paul, “is profitable for all things, having the promise of the life that now is, and of that which is to come.” If eternal salvation were to be sold, for how much, O men, would you propose to purchase it? Were one to estimate the value of the whole of Pactolus, the fabulous river of gold, he would not have reckoned up a price equivalent to salvation.

“Nourish yourselves up in the words of faith. Exercise yourselves unto godliness: for bodily exercise profiteth little; but godliness is profitable for all things, having the promise of the life which now is, and that which is to come.”

24. But concerning what eunuchs speaketh God by the prophet Isaiah, unto whom He saith that He will give in His house and in His wall a place by name, much better than of sons and daughters, save concerning these, who make themselves eunuchs for the sake of the kingdom of heaven? For for these, whose bodily organ is without strength, so that they cannot beget, (such as are the eunuchs of rich men and of kings,) it is surely enough, when they become Christians, and keep the commands of God, yet have this purpose, that, if they could, they would have wives, to be made equal to the rest of the faithful in the house of God, who are married, who bring up in the fear of God a family which they have lawfully and chastely gotten, teaching their sons to set their hope on God; but not to receive a better place than of sons and daughters. …

72. Read the rest: it is too long to quote all. You will find that those able to think lightly of such things, that is, those of greater strength and stability, are told that they must nevertheless abstain, lest those should be offended who from their weakness are still in need of such abstinence. The people I was describing know and observe these things; for they are Christians, not heretics. They understand Scripture according to the apostolic teaching, not according to the presumptuous and fictitious name of apostle. Him that eats not no one despises; him that eats no one judges; he who is weak eats herbs. Many who are strong, however, do this for the sake of the weak; with many the reason for so doing is not this, but that they may have a cheaper diet, and may lead a life of the greatest tranquillity, with the least expensive provision for the support of the body. …

4. “The Lord help him” ( ver. 3 ). But when? Haply in heaven, haply in the life eternal, that so it remain to worship the devil for earthly needs, for the necessities of this life. Far be it! Thou hast “promise of the life that now is, and of that which is to come.” He came unto thee on earth, by Whom were made heaven and earth. Consider then what He saith, “The Lord help him, on his bed of pain.” The bed of pain is the infirmity of the flesh; lest thou shouldest say, I cannot hold, and carry, and tie up my flesh; thou art aided that thou mayest. The Lord help thee on thy bed of pain. …

13. For not because I have fallen, hast Thou grown old: for Thou art strong to set me free, who hast been strong to humble me. “But Thou, O Lord, endurest for ever: and Thy remembrance throughout all generations” ( ver. 12 ). “Thy remembrance,” because Thou dost not forget: “throughout all generations,” forasmuch as we know the promise of life, both present and future.

Ver. 8 . “For bodily exercise profiteth little.” This has by some been referred to fasting; but away with such a notion! for that is not a bodily but a spiritual exercise. If it were bodily it would nourish the body, whereas it wastes and makes it lean, so that it is not bodily. Hence he is not speaking of the discipline of the body. What we need, therefore, is the exercise of the soul. For the exercise of the body hath no profit, but may benefit the body a little, but the exercise of godliness yields fruit and advantage both here and hereafter.

7. And whereas, not only in action, but also in the thoughts of the mind, men are moved to deeds of virtue, he afterwards adds, saying, ‘Mine eyes prevent the dawn, that I might meditate on Thy words.’ For it is meet that the spiritual meditations of those who are whole should precede their bodily actions. And does not our Saviour, when intending to teach this very thing begin with the thoughts of the mind? saying, ‘Whosoever looketh on a woman to lust after her, hath already committed adultery:’ and, ‘Whosoever shall be angry with his brother, is guilty of murder.’ For where there is no wrath, murder is prevented; and where lust is first removed, there can be no accusation of adultery. …

10. For of these two things we speak of, faith and godliness, the hope is the same, even everlasting life; for he saith, ‘Fight the good fight of faith; lay hold on eternal life.’ And, ‘exercise thyself unto godliness, for it hath the promise of the life that now is, and of that which is to come.’ For this cause, the Ario-maniacs, who now have gone out from the Church, being opponents of Christ, have digged a pit of unbelief, into which they themselves have been thrust; and, since they have advanced in ungodliness, they ‘overthrow the faith of the simple;’ blaspheming the Son of God, and saying that He is a creature, and has His being from things which are not. …

184. Think, then, how he teaches those who enter upon their duties in the Church, that they ought to have contempt for all earthly things: “If, then, ye be dead with Christ from the elements of this world, why do ye act as though living in the world? Touch not, taste not, handle not, which all are to perish with the using.” And further: “If ye then be risen with Christ, seek those things which are above, not those things which are on the earth.” And again: “Mortify, therefore, your members which are on the earth.” This, indeed, is meant for all the faithful. But thee, especially, my son, he urges to despise riches and to avoid profane and old wives fables, allowing nothing but this: “Exercise thyself unto godliness, for bodily exercise profiteth a little, but godliness is profitable unto all things.”

23. But we do not reckon usefulness by the value of any gain in money, but in acquiring godliness, as the Apostle says: “But godliness is profitable unto all things, having promise of the life that now is, and of that which is to come.” Thus in the holy Scriptures, if we look carefully we shall often find that what is virtuous is called useful: “All things are lawful unto me, but all things are not profitable” [useful]. Before that he was speaking of vices, and so means: It is lawful to sin, but it is not seemly. Sins rest in one’s own power, but they are not virtuous. To live wantonly is easy, but it is not right. For food serves not God but the belly.

27. There is therefore a usefulness connected with the body, and also one that has to do with godliness, according to the Apostle’s division: “Bodily exercise profiteth a little, but godliness is profitable unto all things.” And what is so virtuous as integrity? what so seemly as to preserve the body unspotted and undefiled, and its purity unsullied? What, again, is so seemly as that a widow should keep her plighted troth to her dead husband? What more useful than this whereby the heavenly kingdom is attained? For “there are some who have made themselves eunuchs for the kingdom of heaven’s sake.”
