1 Corinthians 9:23
“And I do all things for the Gospel's sake, that I may be a joint partaker thereof.”
That is, that I may seem also myself to have added some contribution of my own, and may partake of the crowns laid up for the faithful. For as he spoke of “living of the Gospel,” i.e., of the believers; so also here, “that I may be a joint partaker in the Gospel, that I may be able to partake with them that have believed in the Gospel.” Do you perceive his humility, how in the recompense of rewards he places himself as one of the many, though he had exceeded all in his labors? Whence it is evident that he would in his reward also. Nevertheless, he claims not to enjoy the first prize, but is content if so be he may partake with the others in the crowns laid up for them. But these things he said, not because he did this for any reward, but that hereby at least he might draw them on, and by these hopes might induce them to do all things for their brethren's sake. Do you see his wisdom! Do you see the excellency of his perfection? How he wrought beyond the things commanded, not receiving when it was lawful to receive. Do you see the exceeding greatness of his condescension? How he that was “under law to Christ,” and kept that highest law, “to them that were without law,” was “as one without law,” to the Jews, as a Jew, in either kind showing himself preeminent, and surpassing all.
6. This also do thou, and think not being eminent, that you lower yourself, when for your brother's sake you submit to some abasement. For this is not to fall, but to descend. For he who falls, lies prostrate, hardly to be raised up again; but he who descends shall also rise again with much advantage. As also Paul descended indeed alone, but ascended with the whole world: not acting a part, for he would not have sought the gain of them that are saved had he been acting. Since the hypocrite seeks men's perdition, and feigns, that he may receive, not that he may give. But the apostle not so: as a physician rather, as a teacher, as a father, the one to the sick, the other to the disciple, the third to the son, condescends for his correction, not for his hurt; so likewise did he.
To show that the things which have been stated were not pretence; in a case where he is not compelled to do or say any such thing but means to express his affection and his confidence; hear him saying, “neither life, nor death, nor angels, nor principalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God which is in Christ Jesus our Lord.” Do you see a love more ardent than fire? So let us also love Christ. For indeed it is easy, if we will. For neither was the Apostle such by nature. On this account, you see, his former life was recorded, so contrary to this, that we may learn that the work is one of choice, and that to the willing all things are easy.
Let us not then despair, but even though thou be a reviler, or covetous, or whatsoever you are, consider that Paul was “a blasphemer, and persecutor, and injurious, and the chief of sinners,” and suddenly rose to the very summit of virtue, and his former life proved no hindrance to him. And yet none with so great frenzy clings to vice as he did to the war against the Church. For at that time he put his very life into it; and because he had not ten thousand hands that he might stone Stephen with all of them, he was vexed. Notwithstanding, even thus he found how he might stone him with more hands, to wit, those of the false witnesses whose clothes he kept. And again, when he entered into houses like a wild beast and no otherwise did he rush in, haling, tearing men and women, filling all things with tumult and confusion and innumerable conflicts. For instance, so terrible was he that the Apostles, even after his most glorious change, did not yet venture to join themselves to him. Nevertheless, after all those things he became such as he was: for I need not say more.
7. Where now are they who build up the necessity of fate against the freedom of the will? Let them hear these things, and let their mouths be stopped. For there is nothing to hinder him that wills to become good, even though before he should be one of the vilest. And in fact we are more aptly disposed that way, inasmuch as virtue is agreeable to our nature, and vice contrary to it, even as sickness and health. For God has given us eyes, not that we may look wantonly, but that, admiring his handi-work, we may worship the Creator. And that this is the use of our eyes is evident from the things which are seen. For the lustre of the sun and of the sky we see from an immeasurable distance, but a woman's beauty one cannot discern so far off. Do you see that for this end our eye was chiefly given? Again, he made the ear that we should entertain not blasphemous words, but saving doctrines. Wherefore you see, when it receives any thing dissonant, both our soul shudders and our very body also. “For,” says one, “the talk of him that swears much makes the hair stand upright.” And if we hear any thing cruel or merciless, again our flesh creeps; but if any thing decorous and kind, we even exult and rejoice. Again, if our mouth utter base words, it causes us to be ashamed and hide ourselves, but if grave words, it utters them with ease and all freedom. Now for those things which are according to nature no one would blush, but for those which are against nature. And the hands when they steal hide themselves, and seek excuses; but if they give alms, they even glory. So that if we will, we have from every side a great inclination towards virtue. But if you talk to me of the pleasure which arises from vice, consider that this also is a thing which we reap more of from virtue. For to have a good conscience and to be looked up to by all and to entertain good hopes, is of all things most pleasant to him that has seen into the nature of pleasure, even as the reverse is of all things the most grievous to him that knows the nature of pain; such as to be reproached by all, to be accused by our own conscience, to tremble and fear both at the future and the present.
And that what I say may become more evident, let us suppose for argument's sake one man having a wife, yet defiling the marriage-bed of his neighbor and taking pleasure in this wicked robbery, enjoying his paramour. Then let us again oppose to him another who loves his own spouse. And that the victory may be greater and more evident, let the man who enjoys his own wife only, have a fancy also for the other, the adulteress, but restrain his passion and do nothing evil: (although neither is this pure chastity.) However, granting more than is necessary, that you may convince yourself how great is the pleasure of virtue, for this cause have we so framed our story.
