Ambrose of Milan : Some indeed put it thus, "Incline my heart unto Thy testimonies and not to what is useful." The reference is to that kind of usefulness which is always on the watch for making gains in business and has been bent and diverted by the habits of men to the pursuit of money. For as a rule most people call that only useful which is profitable, but we are speaking of that kind of usefulness which is sought in earthly loss "that we may gain Christ," whose gain is "godliness with contentment." Great, too, is the gain whereby we attain to godliness, which is rich with God, not indeed in fleeting wealth but in eternal gifts, and in which rests no uncertain trial but grace constant and unending. 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 profits a little, but godliness is profitable for all things." — On the Duties of the Clergy 2.6.26-27 Augustine of Hippo : "Godliness," then, "which is the true worship of God, is profitable to all things," since it deflects or blunts the troubles of this life and leads to that other life, our salvation, where we shall suffer no evil and enjoy the supreme and everlasting good. I exhort you as I do myself to pursue this happiness more earnestly and to hold to it with strong constancy. — LETTERS 155.2.17 Dionysius of Alexandria : Those who are too hasty, and give up even before midnight, we reprehend as remiss and intemperate, and as almost breaking off from their course in their precipitation, for it is a wise man's word, "That is not little in life which is within a little." And those who hold out and continue for a very long time, and persevere even on to the fourth watch, which is also the time at which our Saviour manifested Himself walking upon the sea to those who were then on the deep, we receive as noble and laborious disciples. On those, again, who pause and refresh themselves in the course as they are moved or as they are able, let us not press very hard: for all do not carry out the six days of fasting either equally or alike; but some pass even all the days as a fast, remaining without food through the whole; while others take but two, and others three, and others four, and others not even one. — Containing Various Sections of the Works John Cassian : St. Paul is plainly referring to this when he says, "bodily exercise is profitable for a little, but godliness" (by which he surely means charity) "is profitable for all things, having the promise of the life that now is and of the life to come." What is said to be profitable for a little cannot be profitable forever and cannot (of itself) bring a man to the perfect life. The phrase "for a little" might mean one of two things. It might mean "for a short time," since these bodily exercises are not going to last as long as the man who practices them. Or it might mean "only of little profit." Corporal austerity brings the first beginnings of progress, but it does not beget that perfect charity which has the promise of this life and the life to come. — CONFERENCES 1.10 John Chrysostom : "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. — Homily on 1 Timothy 12 Oecumenius : Train yourself to godliness; for physical exercise is of little profit, but godliness is profitable for all things, having promise of the life that now is and of that which is to come. Train. That is, accustom yourself. to godliness. Godliness is the diligence and zeal of life with right faith. for physical exercise. It makes the body healthy. However, in comparison it is only for a short time. having promise of the life. Do you see the benefit? That godliness also in the present and in the future life gives life to the spiritual life. — COMMENTARY ON 1 TIMOTHY
