Luke 22:35

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.

(cont. Faust. lib. xxii. c. 77.) By no inconsistency then of Him who commands, but by the reason of the dispensation, according to the diversity of times are commandments, counsels, or permissions changed.

Our Lord had foretold to Peter that he should deny Him; namely, at the time of His being taken. But having once made mention of His being taken captive, He next announces the struggle that would ensue against the Jews. Hence it is said, And he said unto them, When I sent you without purse, &c. For the Saviour had sent the holy Apostles to preach in the cities and towns the kingdom of heaven, bidding them to take no thought of the things of the body, but to place their whole hope of salvation in Him.

(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.

While they were contending among themselves above concerning priority, He saith, It is not a time of dignities, but rather of danger and slaughter. Behold I even your Master am led to a disgraceful death, to be reckoned with the transgressors. For these things which are prophesied of Me have an end, that is, a fulfilment. Wishing then to hint at a violent attack, He made mention of a sword, not altogether revealing it, lest they should be seized with dismay, nor did He entirely provide that they should not be shaken by these sudden attacks, but that afterwards recovering, they might marvel how He gave Himself up to the Passion, a ransom for the salvation of men. Or He hereby foretels to them that they would incur hunger and thirst, which He implies by the scrip, and sundry kinds of misery, which he intends by the sword. Our Lord then was unwilling to blame them as not understanding Him, but saying, It is enough, He dismissed them; as when we are addressing any one, and see that he does not understand what is said, we say, Well, let us leave him, lest we trouble him. But some say, that our Lord said, It is enough, ironically; as if He said, Since there are two swords, they will amply suffice against so large a multitude as is about to attack us.
