1 Corinthians 4:2
So also in regard of wealth. If you enjoy it alone, you too have lost it: for you will not reap its reward. But if you possess it jointly with the rest, then will it be more your own, and then will you reap the benefit of it. Do you see not that the hands minister, and the mouth softens, and the stomach receives? Does the stomach say, Since I have received, I ought to keep it all? Then do not thou I pray, in regard to riches, use this language. For it belongs to the receiver to impart. As then it is a vice in the stomach to retain the food and not to distribute it, (for it is injurious to the whole body,) so it is a vice in those that are rich to keep to themselves what they have. For this destroys both themselves and others. Again, the eye receives all the light: but it does not itself alone retain it, but enlightens the entire body. For it is not its nature to keep it to itself, so long as it is an eye. Again, the nostrils are sensible of perfume; but they do not keep it all to themselves, but transmit it to the brain, and affect the stomach with a sweet savor, and by their means refresh the entire man. The feet alone walk; but they move not away themselves only, but transfer also the whole body. In like manner do thou, whatsoever you have been entrusted withal, keep it not to yourself alone, since you are doing harm to the whole and to yourself more than all.
And not in the case of the limbs only may one see this occuring: for the smith also, if he chose to impart of his craft to no one, ruins both himself and all other crafts. Likewise the cordwainer, the husbandman, the baker, and everyone of those who pursue any necessary calling; if he chose not to communicate to anyone of the results of his art, will ruin not the others only but himself also with them.
And why do I say, “the rich?” For the poor too, if they followed after the wickedness of you who are covetous and rich, would injure you very greatly and soon make you poor; yea rather, they would quite destroy you, were they in your want unwilling to impart of their own: the tiller of the ground, (for instance,) of the labor of his hands; the sailor, of the gain from his voyages; the soldier, of his distinction won in the wars.
Wherefore if nothing else can, yet let this at least put you to shame, and do you imitate their benevolence. Do you impart none of your wealth unto any? Then should you not receive any thing from another: in which case, the world will be turned upside down. For in every thing to give and receive is the principle of numerous blessings: in seeds, in scholars, in arts. For if any one desire to keep his art to himself, he subverts both himself and the whole course of things. And the husbandman, if he bury and keep the seeds in his house, will bring about a grievous famine. So also the rich man, if he act thus in regard of his wealth, will destroy himself before the poor, heaping up the fire of hell more grievous upon his own head.
8. Therefore as teachers, however many scholars they have, impart some of their lore unto each; so let your possession be, many to whom you have done good. And let all say, “such an one he freed from poverty, such an one from dangers. Such an one would have perished, had he not, next to the grace of God, enjoyed your patronage. This man's disease you cured, another you rid of false accusation, another being a stranger you took in, another being naked you clothed.” Wealth inexhaustible and many treasures are not so good as such sayings. They draw all men's gaze more powerfully than your golden vestments, and horses, and slaves. For these make a man appear even odious: (φορτικόν, a conj. of Saville's for φορτικά) they cause him to be hated as a common foe; but the former proclaim him as a common father and benefactor. And, what is greatest of all, Favor from God waits on you in every part of your proceedings. What I mean is, let one man say, He helped to portion out my daughter: another, And he afforded my son the means of taking his station among men: (εἰς ἄνδρας ἐμφανῆναι) another, He made my calamity to cease: another, He delivered me from dangers. Better than golden crowns are words such as these, that a man should have in his city innumerable persons to proclaim his beneficence. Voices such as these are pleasanter far, and sweeter than the voices of the heralds marching before the archons; to be called saviour, benefactor, defender, (the very names of God;) and not, covetous, proud, insatiate, and mean. Let us not, I beseech you, let us not have a fancy for any of these titles, but the contrary. For if these, spoken on earth, make one so splendid and illustrious; when they are written in heaven, and God proclaims them on the day that shall come, think what renown, what splendor you shall enjoy! Which may it be the lot of us all to obtain, through the grace and loving-kindness of our Lord Jesus Christ; with Whom unto the Father and the Holy Spirit, be glory, power, honor, now and always and unto everlasting ages. Amen.
