Matthew 13:6

What then comes of this seed? Three parts perish, and one is saved. "And when He sowed, some seeds fell," He saith, "by the way side; and the fowls came and devoured them up." He said not, that He cast them, but that "they fell." A fourth part is saved; and not this all alike, but even here great is the difference. Now these things He said, manifesting that He discoursed to all without grudging. For as the sower makes no distinction in the land submitted to him, but simply and indifferently casts his seed; so He Himself too makes no distinction of rich and poor, of wise and unwise, of slothful or diligent, of brave or cowardly; but He discourses unto all, fulfilling His part, although foreknowing the results; that it may be in His power to say, "What ought I to have done, that I have not done?" And the prophets speak of the people as of a vine; "For my beloved," it is said, "had a vineyard;" and, "He brought a vine out of Egypt;" but He, as of seed. What could this be to show? That obedience now will be quick and easier, and will presently yield its fruit. But when thou hearest, "The sower went forth to sow," think it not a needless repetition. For the sower frequently goes forth for some other act also, either to plough, or to cut out the evil herbs, or to pluck up thorns, or to attend to some such matter; but He went forth to sow. Whence then, tell me, was the greater part of the seed lost? Not through the sower, but through the ground that received it; that is, the soul that did not hearken. And wherefore doth He not say, Some the careless received, and lost it; some the rich, and choked it, and some the superficial, and betrayed it? It is not His will to rebuke them severely, lest He should cast them into despair, but He leaves the reproof to the conscience of His hearers. And this was not the case with the seed only, but also with the net; for that too produced many that were unprofitable. But this parable He speaks, as anointing His disciples, and to teach them, that even though the lost be more than such as receive the word yet they are not to despond. For this was the case even with their Lord, and He who fully foreknew that these things should be, did not desist from sowing. And how can it be reasonable, saith one, to sow among the thorns, on the rock, on the wayside? With regard to the seeds and the earth it cannot be reasonable; but in the case of men's souls and their instructions, it hath its praise, and that abundantly. For the husbandman indeed would reasonably be blamed for doing this; it being impossible for the rock to become earth, or the wayside not to be a wayside, or the thorns, thorns; but in the things that have reason it is not so. There is such a thing as the rock changing, and becoming rich land; and the wayside being no longer trampled on, nor lying open to all that pass by, but that it may be a fertile field; and the thorns may be destroyed, and the seed enjoy full security. For had it been impossible, this Sower would not have sown. And if the change did not take place in all, this is no fault of the Sower, but of them who are unwilling to be changed: He having done His part: and if they betrayed what they received of Him, He is blameless, the exhibitor of such love to man. But do thou mark this, I pray thee; that the way of destruction is not one only, but there are differing ones, and wide apart from one another. For they that are like the wayside are the coarse-minded, and indifferent, and careless; but those on the rock such as fail from weakness only.

This parable Valentinus lays hold of to establish his heresy, bringing in three different natures; the spiritual, the natural or the animal, and the earthly. But there are here four named, one by the wayside, one stony, one thorny, and a fourth the good ground.

But those things which He silently left to our understanding, should be shortly noticed. The wayside is the mind trodden and hardened by the continual passage of evil thoughts; the rock, the hardness of the self-willed mind; the good soil, the gentleness of the obedient mind, the sun, the heat of a raging persecution. The depth of soil, is the honesty of a mind trained by heavenly discipline. But in thus expounding them we should add, that the same things are not always put in one and the same allegorical signification.
