Luke 22:36

(Reg. Brev. int. 31.) Or the Lord does not bid them carry purse and scrip and buy a sword, but predicts that it should come to pass, that in truth the Apostles, forgetful of the time of the Passion, of the gifts and law of their Lord, would dare to take up the sword. For often does the Scripture make use of the imperative form of speech in the place of prophecy. Still in many books we do not find, Let him take, or buy, but, he will take, he will buy.

What is, this? He who said, If any one strike you on the right cheek, turn unto him the other also, (Matt. 5:39.) now arms His disciples, and with a sword only. For if it were fitting to be completely armed, not only must a man possess a sword, but shield and helmet. But even though a thousand had arms of this kind, how could the eleven be prepared for all the attacks and lying in wait of people, tyrants, allies, and nations, and how should they not quake at the mere sight of armed men, who had been brought up near lakes and rivers? We must not then suppose that He ordered them to possess swords, but by the swords He points at the secret attack of the Jews. And hence it follows, For I say unto you, that this that is written must be accomplished in me: And he was numbered with the transgressors. (Isa. 53:12.)

Or else; When our Lord says, He who hath a purse, let him take it, likewise a scrip, His discourse He addressed to His disciples, but in reality He regards every individual Jew; as if He says, If any Jew is rich in resources, let him collect them together and fly. But if any one oppressed with extreme poverty applies himself to religion, let him also sell his cloak and buy a sword. For the terrible attack of battle shall overtake them, so that nothing shall suffice to resist it.

But He who forbids to strike, why does He order them to buy a sword? unless perchance that there may be a defence prepared, but no necessary retaliation; a seeming ability to be revenged, without the will. Hence it follows, And he who has not, (that is, a purse,) let him sell his garment, and buy a sword. Or, because the law does not forbid to return a blow, perhaps He says to Peter, as he is offering the two swords, It is enough, as though it were lawful until the Gospel; in order that there may be in the law, the knowledge of justice; in the Gospel, perfection of goodness. There is also a spiritual sword, that you may sell your patrimony, and buy the word, by which the nakedness of the soul is clothed. There is also a sword of suffering, so that you may strip your body, and with the spoils of your sacrificed flesh purchase for yourself the sacred crown of martyrdom. Again it moves, seeing that the disciples put forward two swords, whether perhaps one is not of the Old Testament, the other of the New, whereby we are armed against the wiles of the devil. Therefore the Lord says, It is enough, because he wanted nothing who is fortified by the teaching of both Testaments.

(in illud ad Rom. 16. Salutate Priscillam.) Now as one who teaches to swim, at first indeed placing his hands under his pupils, carefully supports them, but afterward frequently withdrawing his hand, bids them help themselves, nay even lets them sink a little; so likewise did Christ deal with His disciples. At the beginning truly He was present to them, giving them most richly abundance of all things; as it follows, And they said unto them, Nothing. But when it was necessary for them to show their own strength, He withdrew from them for a little His grace, bidding them do something of themselves; as it follows, But now he that hath a purse, that is, wherein to carry money, let him take it, and likewise his scrip, that is, to carry provisions in. And truly when they had neither shoes, nor girdle, nor staff, nor money, they never suffered the want of any thing. But when He allowed them purse and scrip, they seem to suffer hunger, and thirst, and nakedness. As if He said to them, Hitherto all things have been most richly supplied to you, but now I would have you also experience poverty, therefore I hold you no longer to the former rule, but I command you to get purse and scrip. Now God might even to the end have kept them in plenty, but for many reasons He was unwilling to do so. First that they might impute nothing to themselves, but acknowledge that every thing flowed from God; secondly, that they might learn moderation; thirdly, that they might not think too highly of themselves. For this cause while He permitted them to fall into many unlooked for evils, He relaxed the rigour of the former law, lest it should become grievous and intolerable.
