The peculiar turn of the first sentence, The kingdom of heaven is likened unto a man that sowed,' etc., suggests that the main purpose of the parable is to teach the conduct of the king in view of the growth of the tares. The kingdom is concentrated in Him, and the likening' is not effected by the parable, but, as the tenses of both verbs show, by the already accomplished fact of His sowing. Our Lord veils His claims by speaking of the sower in the third person; but the hearing ear cannot fail to catch the implication throughout that He Himself is the sower and the Lord of the harvest. The field is his field,' and His own interpretation tells us that it means the world.' Whatever view we take of the bearing of this parable on purity of communion in the visible Church, we should not slur over Christ's own explanation of the field,' lest we miss the lesson that He claims the whole world as His, and contemplates the sowing of the seed broadcast over it all. The Kingdom of Heaven is to be developed on, and to spread through, the whole earth. The world belongs to Christ not only when it is filled with the kingdom, but before the sowing. The explanation of the good seed takes the same point of view as in the former parable. What is sown is' the word'; what springs from the seed is the new life of the receiver. Men become children of the kingdom by taking the Gospel into their hearts, and thereby receive a new principle of growth, which in truth becomes themselves.
Side by side with the sewer's beneficent work the counter-working of his enemy' goes on. As the one, by depositing holy truth in the heart, makes men children of the kingdom,' the other, by putting evil principles therein, makes men children of evil.' Honest exposition cannot eliminate the teaching of a personal antagonist of Christ, nor of his continuous agency in the corruption of mankind. It is a glimpse into a mysterious region, none the less reliable because so momentary. The sulphurous clouds that hide the fire in the crater are blown aside for an instant, and we see. Who would doubt the truth and worth of the unveiling because it was short and partial? The devil is God's ape.' His work is a parody of Christ's. Where the good seed is sown, there the evil is scattered thickest. False Christs and false apostles dog the true like their shadows. Every truth has its counterfeit, Neither institutions, nor principles, nor movements, nor individuals, bear unmingled crops of good. Not merely creatural imperfection, but hostile adulteration, marks them all. The purest metal oxidises, scum gathers on the most limpid water, every ship's bottom gets foul with weeds. The history of every reformation is the same: radiant hopes darkened, progress retarded, a second generation of dwarfs who are careless or unfaithful guardians of their heritage.
There are, then, two classes of men represented in the parable, and these two are distinguishable without doubt by their conduct. Tares are said to be quite like wheat until the heads show, and then there is a plain difference. So our Lord here teaches that the children of the kingdom and those of evil are to be discriminated by their actions. We need not do more than point in a sentence to His distinct separation of men (where the seed of the kingdom has been sown) into two sets. Jesus Christ holds the unfashionable, narrow' opinion that, at bottom, a man must either be His friend or His enemy. We are too much inclined to weaken the strong line of demarcation, and to think that most men are neither black nor white, but grey.
The question has been eagerly debated whether the tares are bad men in the Church, and whether, consequently, the mingled crop is a description of the Church only. The following considerations may help to an answer. The parable was spoken, not to the disciples, but to the crowd. An instruction to them as to Church discipline would have been signally out of place; but they needed to be taught that the kingdom was to be a rose amidst thorns,' and to grow up among antagonisms which it would slowly conquer, by the methods which the next two parables set forth. This general conception, and not directions about ecclesiastical order, was suited to them. Again, the designation of the tares as the children of evil' seems much too wide, if only a particular class of evil men--namely, those who are within the Church --are meant by it. Surely the expression includes all, both in and outside the Church, who do iniquity.' Further, the representation of the children of the kingdom, as growing among tares in the field of the world, does not seem to contemplate them as constituting a distinct society, whether pure or impure; but rather as an indefinite number of individuals, intermingled in a common soil with the other class. The kingdom of heaven' is not a synonym for the Church. Is it not an anachronism to find the Church in the parable at ally No doubt, tares are in the Church, and the parable has a bearing on it; but its primary lesson seems to me to be much wider, and to reveal rather the conditions of the growth of the kingdom in human society.
