Matthew 13:24

What is the difference between this, and the parable before it? There He speaks of them that have not at all holden with Him, but have started aside, and have thrown away the seed; but here He means the societies of the heretics. For in order that not even this might disturb His disciples, He foretells it also, after having taught them why He speaks in parables. The former parable then means their not receiving Him; this, their receiving corrupters. For indeed this also is a part of the devil's craft, by the side of the truth always to bring in error, painting thereon many resemblances, so as easily to cheat the deceivable. Therefore He calls it not any other seed, but tares; which in appearance are somewhat like wheat. Then He mentions also the manner of his device. For "while men slept," saith He. It is no small danger, which He hereby suspends over our rulers, to whom especially is entrusted the keeping of the field; and not the rulers only, but the subjects too. And He signifies also that the error comes after the truth, which the actual event testifies. For so after the prophets, were the false prophets; and after the apostles, the false apostles; and after Christ, Antichrist. For unless the devil see what to imitate, or against whom to plot, he neither attempts, nor knows how. Now then also, having seen that "one brought forth a hundred, another sixty, another thirty," he proceeds after that another way. That is, not having been able to carry away what had taken root, nor to choke, nor to scorch it up, he conspires against it by another craft, privily casting in his own inventions. And what difference is there, one may say, between them that sleep, and them that resemble the wayside? That in the latter case he immediately caught it away; yea, he suffered it not even to take root; but here more of his craft was needed. And these things Christ saith, instructing us to be always wakeful. For, saith He, though thou quite escape those harms, there is yet another harm. For as in those instances "the wayside," and "the rock," and "the thorns," so here again sleep occasions our ruin; so that there is need of continual watchfulness. Something like this took place even at the beginning. Many of the prelates, I mean, bringing into the churches wicked men, disguised heresiarchs, gave great facility to the laying that kind of snare. For the devil needs not even to take any trouble, when he hath once planted them among us. And how is it possible not to sleep? one may say. Indeed, as to natural sleep, it is not possible; but as to that of our moral faculty, it is possible. After this He points out the thing to be superfluous too, not hurtful only; in that, after the land hath been tilled, and there is no need of anything, then this enemy sows again; as the heretics also do, who for no other cause than vainglory inject their proper venom.

He set forth also this other parable, as it were a rich householder refreshing his guests with various meats, that each one according to the nature of his stomach might find some food adapted to him. He said not 'a second parable,' but another; for had He said 'a second,' we could not have looked for a third; but another prepares us for many more.

Here He calls the Son of God Himself the kingdom of heaven; for He saith, The kingdom of heaven is like unto a man that sowed good seed in his field.

And it should be noted that, when He says, Sowed good seed, He intends that good will which is in the elect; when He adds, An enemy came, He intimates that watch should be kept against him; when as the tares grow up, He suffers it patiently, saying, An enemy hath done this, He recommends to us patience; when He says, Lest haply in gathering the tares, &c. He sets us an example of discretion; when He says, Suffer both to grow together till the harvest, He teaches us long-suffering; and, lastly, He inculcates justice, when He says, Bind them into bundles to burn.
