Labor not for the food which perishes, but for that food which endures unto everlasting life, which the Son of man shall give unto you: for on him has God the Father set his seal.

Cyril of Alexandria
AD 444
Something of this sort doth Paul teach us expanding the discourse universally and more generally, saying, He that soweth to his flesh shall of the flesh reap corruption, but he that soiveth to the Spirit shall of the Spirit reap life everlasting. For he says that they sow to the flesh who giving as it were full rein to the pleasures of the flesh, advance at full speed to whatever they will, by no means distinguishing what is profitable for them from what is hurtful and injurious, nor in any way accustomed to approve what seems good unto the Law-giver, but heedlessly hurried off to that alone which is pleasant and agreeable, and preferring nothing to things seen. Again he affirms that they sow to the Spirit, who expend the whole aim of their mind on those things wherein the Holy Ghost willeth us to excel, employing a mind so intense toward the cultivation of good things, that, did not voice of nature not to be disregarded constrain them to minister needful food to the flesh, they would not endure to descend even to this. I think then that we ought to take no forethought whatever for the flesh for the lusts thereof, but rather to apply ourselves to what is most needful, and to be zealous in practising those things, which bring us to the everlasting and Divine Life. For admiration for the delights of the body, and the esteeming nothing better than the superfluities of the belly, is truly brutish and akin to the extremest folly. But to apply ourselves to good things, and earnestly to strive to excel in virtues, and to be subject to the laws of the Spirit, and with all readiness to seek after the things of God, which are able to support us unto salvation:----I will grant that this truly beseemeth him who knoweth his own nature, and is not ignorant that he hath been made a reasonable creature after the Image of Him that created him. Therefore as the Saviour somewhere saith, Take we no thought, what shall we eat? or, what shall we drink? or, wherewithal shall we be clothed? but considering that the soul is more than meat, and the body than raiment, let us take thought how the more precious part of us may do well.
For though the body do well, and be fat with succession of delights, it will not profit the miserable soul; but on the contrary, will work it much harm. For it will depart into the everlasting fire, since they who have wrought no good, must needs undergo punishment for it: but if the body have been bridled with due reason, and brought under the law of the Spirit, both must surely be saved together. It is then most absurd, that for the flesh we should so take thought, which is but for a time and even now shall perish, as to think that it ought not to lack any one thing which it loves: and to take care for the soul, by way of appendix, or as though it were nothing worth; albeit I think we ought to apply ourselves so much the rather to cares for the soul, as it is of more value than the body. For so of a truth preferring what surpasses in the comparison to what is inferior, and giving a just vote in this matter, we shall become holy and wise jurors, and not bestow upon any other the palm of right reasoning, but rather shall put it upon our own heads. Let us then, as the Saviour saith, labour not for the meat which perisheth, which when it hath passed into the belly, and for a very little while deluded the mind with pettiest pleasure, goeth out into the draught, and is conveyed forth again from the belly. But the spiritual food which strengthened the heart, keepeth the man unto life everlasting, which also Christ promiseth to give us, saying, Which the Son of Man shall give unto you; at once knitting the human with that which is Divine, and connecting the whole mystery of the economy with Flesh in its order. But He hints, I suppose, at the Mystic and more Spiritual Food, whereby we live in Him, sanctified in body and soul. But we shall see Him speaking more openly of this hereafter. The discourse then must be kept for its fit time and place.
