1 Corinthians 13:3
11 And that you may learn how great a work of virtue it is, let us sketch it out in word, since in deeds we see it no where appearing; and let us consider, if it were every where in abundance, how great benefits would ensue: how there were no need then of laws, or tribunals or punishments, or avenging, or any other such things since if all loved and were beloved, no man would injure another. Yea, murders, and strifes, and wars, and divisions, and rapines, and frauds, and all evils would be removed, and vice be unknown even in name. Miracles, however, would not have effected this; they rather puff up such as are not on their guard, unto vain-glory and folly.
Again: what is indeed the marvellous part of love; all the other good things have their evils yoked with them: as he that gives up his possessions is oftentimes puffed up on this account: the eloquent is affected with a wild passion for glory; the humble-minded, on this very ground, not seldom thinks highly of himself in his conscience. But love is free from every such mischief. For none could ever be lifted up against the person whom he loves. And do not, I pray, suppose one person only loving but all alike; and then will you see its virtue. Or rather, if you will, first suppose one single person beloved, and one loving; loving, however, as it is meet to love. Why, he will so live on earth as if it were heaven, every where enjoying a calm and weaving for himself innumerable crowns. For both from envy, and wrath, and jealousy, and pride, and vain-glory, and evil concupiscence, and every profane love, and every distemper, such a man will keep his own soul pure. Yea, even as no one would do himself an injury so neither would this man his neighbors. And being such, he shall stand with Gabriel himself, even while he walks on earth.
Such then is he that has love. But he that works miracles and has perfect knowledge, without this, though he raises ten thousand from the dead, will not be much profited, broken off as he is from all and not enduring to mix himself up with any of his fellow-servants. For no other cause than this did Christ say that the sign of perfect love towards Him is the loving one's neighbors. For, “if you love Me,” says He, “O Peter, more than these, feed My sheep.” Do you see how hence also He again covertly intimates, in what case this is greater than martyrdom? For if any one had a beloved child in whose behalf he would even give up his life, and some one were to love the father, but pay no regard whatever to the son, he would greatly incense the father; nor would he feel the love for himself, because of the overlooking his son. Now if this ensue in the case of father and son, much more in the case of God and men: since surely God is more loving than any parents.
Wherefore, having said, “The first and great commandment is, You shall love the Lord your God,” he added, “and the second— (He leaves it not in silence, but sets it down also)— is like it, You shall love your neighbor as yourself.” And see how with nearly the same excellency He demands also this. For as concerning God, He says, “with all your heart:” so concerning your neighbor, “as yourself,” which is tantamount to, “with all your heart.”
Yea, and if this were duly observed, there would be neither slave nor free, neither ruler nor ruled, neither rich nor poor, neither small nor great; nor would any devil then ever have been known: I say not, Satan only, but whatever other such spirit there be, nay, rather were there a hundred or ten thousand such, they would have no power, while love existed. For sooner would grass endure the application of fire than the devil the flame of love. She is stronger than any wall, she is firmer than any adamant; or if you can name any material stronger than this the firmness of love transcends them all. Her, neither wealth nor poverty overcomes: nay, rather there would be no poverty, no unbounded wealth, if there were love, but the good parts only from each estate. For from the one we should reap its abundance, and from the other its freedom from care: and should neither have to undergo the anxieties of riches, nor the dread of poverty.
12. And why do I mention the advantages arising from it? Yea, rather consider how great a blessing it is of itself to exercise love; what cheerfulness it produces, in how great grace it establishes the soul; a thing which above all is a choice quality of it. For the other parts of virtue have each their troubles yoked with them; as fasting, temperance, watching, have envy, concupiscence, and contempt. But love along with the gain has great pleasure, too, and no trouble, and like an industrious bee, gathering the sweets from every flower, deposits them in the soul of him who loves. Though any one be a slave, it renders slavery sweeter that liberty. For he who loves rejoices not so much in commanding, as in being commanded, although to command is sweet: but love changes the nature of things and presents herself with all blessings in her hands, gentler than any mother, wealthier than any queen, and makes difficulties light and easy, causing our virtues to be facile, but vice very bitter to us. As thus: to expend seems grievous, yet love makes it pleasant: to receive other men's goods, pleasant, but love suffers it not to appear pleasant, but frames our minds to avoid it as an evil. Again, to speak evil seems to be pleasant to all; but love, while she makes this out to be bitter, causes speaking well to be pleasant; for nothing is so sweet to us as to be praising one whom we love. Again, anger has a kind of pleasure; but in this case no longer, rather all its sinews are taken away. Though he that is beloved should grieve him who loves him, anger no where shows itself; but tears and exhortations, and supplications; so far is love from being exasperated: and should she behold one in error, she mourns and is in pain; yet even this pain itself brings pleasure. For the very tears and the grief of love, are sweeter than any mirth and joy. For instance: they that laugh are not so refreshed as they that weep for their friends. And if you doubt it, stop their tears; and they repine at it not otherwise than as persons intolerably ill-used. “But there is,” said one, “an unbecoming pleasure in love.” Go away, and hold your peace, whoever you are. For nothing is so pure from such pleasure as genuine love.
For tell me not of this ordinary sort, the vulgar and low-minded, and a disease rather than love, but of this which Paul seeks after, which considers the profit of them that are loved; and you shall see that no fathers are so affectionate as persons of this stamp. And even as they who love money cannot endure to spend money, but would with more pleasure be in straits than see their wealth diminishing: so too, he that is kindly affected towards any one, would choose to suffer ten thousand evils than see his beloved one injured.
