9. And now addressing the few that remained: "Then said Jesus to the twelve" (namely, those twelve who remained), "Will ye also," said He, "go away?" Not even Judas departed. But it was already manifest to the Lord why he remained: to us he was made manifest afterwards. Peter answered in behalf of all, one for many, unity for the collective whole: "Then Simon Peter answered Him, Lord, to whom shall we go?" Thou drivest us from Thee; give us Thy other self. "To whom shall we go?" If we abandon Thee, to whom shall we go? "Thou hast the words of eternal life." See how Peter, by the gift of God and the renewal of the Holy Spirit, understood Him. How other than because he believed? "Thou hast the words of eternal life." For Thou hast eternal life in the ministration of Thy body and blood. "And we have believed and have known." Not have known and believed, but "believed and known." For we believed in order to know; for if we wanted to know first, and then to believe, we should not be able either to know or to believe. What have we believed and known? "That Thou art Christ, the Son of God;" that is, that Thou art that very eternal life, and that Thou givest in Thy flesh and blood only that which Thou art.
10. Then said the Lord Jesus: "Have not I chosen you twelve, and one of you is a devil?" Therefore, should He have said, "I have chosen eleven:" or is a devil also chosen, and among the elect? Persons are wont to be called "elect" by way of praise: or was man elected because some great good was done by him, without his will and knowledge? This belongs peculiarly to God; the contrary is characteristic of the wicked. For as wicked men make a bad use of the good works of God; so, on the contrary, God makes a good use of the evil works of wicked men. How good it is that the members of the body are, as they can be disposed only by God, their author and framer! Nevertheless what evil use doth wantonness make of the eyes? What ill use doth falsehood make of the tongue? Does not the false witness first both slay his own soul with his tongue, and then, after he has destroyed himself, endeavor to injure another? He makes an ill use of the tongue, but the tongue is not therefore an evil thing; the tongue is God's work, but iniquity makes an ill use of that good work of God. How do they use their feet who run into crimes? How do murderers employ their hands? And what ill use do wicked men make of those good creatures of God that lie outside of them? With gold they corrupt judgment and oppress the innocent. Bad men make a bad use of the very light; for by evil living they employ even the very light with which they see into the service of their villanies. A bad man, when going to do a bad deed, wishes the light to shine for him, lest he stumble; he who has already stumbled and fallen within; that which he is afraid of in his body has already befallen him in his heart. Hence, to avoid the tediousness of running through them separately, a bad man makes a bad use of all the good creatures of God: a good man, on the contrary, makes a good use of the evil deeds of wicked men. And what is so good as the one God? Since, indeed, the Lord Himself said, "There is none good, but the one God." [542] By how much He is better, then, by so much the better use He makes of our evil deeds. What worse than Judas? Among all that adhered to the Master, among the twelve, to him was committed the common purse; to him was allotted the dispensing for the poor. Unthankful for so great a favor, so great an honor, he took the money, and lost righteousness: being dead, he betrayed life: Him whom he followed as a disciple, he persecuted as an enemy. All this evil was Judas's; but the Lord employed his evil for good. He endured to be betrayed, to redeem us. Behold, Judas's evil was turned to good. How many martyrs has Satan persecuted! If Satan left off persecuting, we should not to-day be celebrating the very glorious crown of Saint Laurence. If then God employs the evil works of the devil himself for good, what the bad man effects, by making a bad use, is to hurt himself, not to contradict the goodness of God. The Master makes use of that man. And if He knew not how to make use of him, the Master contriver would not have permitted him to be. Therefore, He saith, "One of you is a devil," whilst I have chosen you twelve. This saying, "I have chosen you twelve," may be understood in this way, that twelve is a sacred number. For the honor of that number was not taken away because one was lost, for another was chosen into the place of the one that perished. [543] The number remained a sacred number, a number containing twelve: because they were to make known the Trinity throughout the whole world, that is, throughout the four quarters of the world. That is the reason of the three times four. Judas, then only cut himself off, not profaned the number twelve: he abandoned his Teacher, for God appointed a successor to take his place.
11. All this that the Lord spoke concerning His flesh and blood;--and in the grace of that distribution He promised us eternal life, and that He meant those that eat His flesh and drink His blood to be understood, from the fact of their abiding in Him and He in them; and that they understood not who believed not; and that they were offended through their understanding spiritual things in a carnal sense; and that, while these were offended and perished, the Lord was present for the consolation of the disciples who remained, for proving whom He asked, "Will ye also go away?" that the reply of their steadfastness might be known to us, for He knew that they remained with Him;--let all this, then, avail us to this end, most beloved, that we eat not the flesh and blood of Christ merely in the sacrament, as many evil men do, but that we eat and drink to the participation of the Spirit, that we abide as members in the Lord's body, to be quickened by His Spirit, and that we be not offended, even if many do now with us eat and drink the sacraments in a temporal manner, who shall in the end have eternal torments. For at present Christ's body is as it were mixed on the threshing-floor: "But the Lord knoweth them that are His." [544] If thou knowest what thou threshest, that the substance is there hidden, that the threshing has not consumed what the winnowing has purged; certain are we, brethren, that all of us who are in the Lord's body, and abide in Him, that He also may abide in us, have of necessity to live among evil men in this world even unto the end. I do not say among those evil men who blaspheme Christ; for there are now few found who blaspheme with the tongue, but many who do so by their life. Among those, then, we must necessarily live even unto the end.
12. But what is this that He saith: "He that abideth in me, and I in him"? What, but that which the martyrs heard: "He that persevereth unto the end, the same shall be saved"? [545] How did Saint Laurence, whose feast we celebrate to-day, abide in Him? He abode even to temptation, abode even to tyrannical questioning, abode even to bitterest threatening, abode even to destruction;--that were a trifle, abode even to savage torture. For he was not put to death quickly, but tormented in the fire: he was allowed to live a long time; nay, not allowed to live a long time, but forced to die a slow, lingering death. Then, in that lingering death, in those torments, because he had well eaten and well drunk, as one who had feasted on that meat, as one intoxicated with that cup, he felt not the torments. For He was there who said, "It is the Spirit that quickeneth." For the flesh indeed was burning, but the Spirit was quickening the soul. He shrunk not back, and he mounted into the kingdom. But the holy martyr Xystus, whose day we celebrated five days ago, had said to him, "Mourn not, my son;" for Xystus was a bishop, he was a deacon. "Mourn not," said he; "thou shall follow me after three days." He said three days, meaning the interval between the day of Saint Xystus's suffering and that of Saint Laurence's suffering, which falls on to-day. Three days is the interval. What comfort! He says not, "Mourn not, my son; the persecution will cease, and thou wilt be safe;" but, "do not mourn: whither I precede thou shalt follow; nor shall thy pursuit be deferred: three days will be the interval, and thou shalt be with me." He accepted the oracle, vanquished the devil, and attained to the triumph.
