Idolatry, for example, is a leaven that must have been small in its beginning, but at a very early date it had grown great. The world was idolatrous when Abraham was called out to become the nucleus of a religious nation; and even his descendants, though constituted as a commonwealth expressly for the purpose of maintaining the worship of the true God while all the world beside had sunk into idolatry, were, through contact with the contaminating leaven, frequently overrun by the same sin. It became necessary that they should be poured from vessel to vessel, and tried as by fire, in order to keep them separate.
Small and apparently harmless Popery began: with the power and perseverance of a principle in nature it spread and defiled the Church. How completely that leaven penetrated the lump may be seen everywhere throughout Europe, in the architecture, sculpture, paintings,—in the laws, habits, and language that have come down from the middle ages to our own day. The evil spirit of the Papacy has intruded into every place; into the councils of kings, into the laws of nations, into the births, marriages, and deaths of the people. Between ruler and subject, between husband and wife, between parent and child, comes the priest, gliding in like water through seamy walls, sapping their foundations. Into the inmost heart of maid, wife, mother, creeps the confessional, tainting, souring, defiling society in its springs,—a leaven of malice and wickedness, a leaven at once of Pharisee and Sadducee, a superstition that believes everything in alliance with a scepticism that believes nothing, and all combined to conceal the salvation of God and enslave the spirits of men. Beware of the leaven of the Papacy.
Other things of grosser and more material mould follow the law of leaven in their progress from small to great, until they obtain the mastery of a community or a man. Such, for example, are the use of ardent spirits in Scotland and the use of opium in China. A hundred years ago how small was either bit! but being a bit of leaven, when it is once introduced it creeps stealthily forward, the appetite growing by what it feeds on, until it dominates, and in some cases utterly destroys. These creeping leavens stain the beauty and waste the strength of nations. Some tribes of Indians in North America have been annihilated mainly by this process; and at this day the Canadian Parliament, through a benevolent law, sanctioned by the Sovereign, entirely prohibit the sale of spirits to the Indians, and thus save from extinction the remnants of the tribes that live under our protection. Those subtile and powerful material agents which create abnormal appetites and influence the moral habits of a whole people, afford ample room for gravest thought both to Christians and patriots.
The fact acknowledged in Scripture, and manifest in all experience, that evil has transfused itself through humanity like leaven, serves to bring out in deeper relief the comforting converse truth which Christ has embodied in this parable. The universal diffusion of corruption in the world becomes a dark ground whereon the Lord may more vividly portray the progress and final triumph of holiness. Good introduced among the good is not much noticed; but when good assails, overcomes, and transforms evil, its power and beauty are conspicuously displayed. Employing the sad facts already stated as shadows filled in to make the lines of light more visible, I shall proceed now to express and enforce positively some of the practical lessons which the parable contains.
1. Christ, the Son of God, became man and dwelt among us. Behold the piece of leaven that has been plunged into the dead mass of the world! “In him was life, and the life was the light of men” (John i. 4). The whole is not leavened yet, but the germ has been introduced. The meaning of Immanuel is, “God with us:” the incarnation is the link that binds the fallen to the throne of God. One without sin and with omnipotence has become our brother,—has taken hold of our nature, and will keep hold of it to the end. He will not fail nor be discouraged. To him every knee shall bow, and every tongue confess: the prophecy has been written, and the history will follow. In the meantime, while we wait for the accomplishment of the promise, we may obtain from this parable some glimpses of the method by which the change will be effected at last.
Leaven consists in, or at least causes, fermentation. The name suggests the mechanical process of boiling. The most sublime and awful scenes which nature has ever presented have been produced in this way. When great masses are affected, a boiling becomes unspeakably grand and terrible. This earth, now so solid beneath, and so green on the surface, seems to have been once a boiling mass. Those mountains that cleave the clouds are the bubbles that rose to the surface and were congealed ere they had time to subside again: there they stand to-day, monuments of the fact. The moral government of God is like the natural. The Maker’s method, when he would bring down the high things and exalt the low, is to throw in an ingredient which will produce fermentation. He can make the world of spirit fervid as well as this material globe. The earth is shaken by moral causes. The Gospel sends a sword before it brings peace. Wars and rumours of wars rend the nations, and make men’s hearts melt within their breasts. In some cases it is obviously Christian truth plunged into the mass that agitates the nations; and if we were able to discern the links of cause and effect a few degrees further into the fringes of the cloud that encircles God’s throne, we would perhaps see the same central fact setting in motion more distant forces. Our life is so short, and our range of vision so contracted, that we cannot observe the progress which the kingdom makes. Sometimes, and in some places, it seems to recede; but when the end comes it will be seen that every step of apparent retreat was the couching in preparation for another spring. The kingdoms of this world shall become the kingdoms of our Lord and of his Christ. The captive’s chains shall be broken, whether they bind more directly the body or the soul, although the ancient political organizations of Europe, and the more recent fabrics of America, should be torn asunder and tossed away in the process, as foam is tossed from the crest of a wave upon the shore. “Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter’s vessel. Be wise now therefore, O ye kings; be instructed, ye judges of the earth. Serve the Lord with fear, and rejoice with trembling. Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him” (Ps. ii. 9–12).
2. Converted men, women, and children are let into openings of corrupt humanity, and hidden in its heart. There they cannot lie still: they stir, and effervesce, and inoculate the portions with which they are in closest contact. In this respect the lesson is the same with that which is taught in those other short parables of Jesus,—“Ye are the light of the world. Ye are the salt of the earth.”
Nor is the conception essentially different from that of Christ or his word dropped into the lump of humanity; for Christians have no life and no expansive power, except in as far as Christ dwells in their hearts by faith. They are vessels which contain the truth, and when these vessels are hidden under the folds of families and larger communities, the word of life, which is within them, touches and tells upon their neighbours.
The most recent experience of the Church exhibits the kingdom spreading like leaven, as vividly, perhaps, as any experience since apostolic times. By contact with one soul, already fervid with new life, other souls, hitherto dead, become fervid too. One sinner saved, his heart burning within his breast, as he consciously communes with his Saviour, touches a meeting and sets it all aglow; the prayer-meeting thus moved touches the congregation and throws its settled lees into an unwonted and violent commotion; this assembly, all throbbing with the cry, What must we do to be saved? infects a city; and the city so infected communicates its fervour to the land; and a nation thus on fire kindles another by its far-reaching sympathy beyond intervening seas. Thus some portions of the world have been thrown into such a state of effervescence, by the leaven of the Gospel hidden in their heart, that for a time the sound of praise for sin forgiven has risen in the highways and market-places, louder than that other old, strong cry, What shall we eat, and what shall we drink, and wherewithal shall we be clothed?
The leaven, like gravitation, follows the same law on smaller spheres that it follows on the larger. Brother infects sister, and sister brother; parent child, and child parent; shopman shopmate. We often lament the contagious influence of evil, and it is right that we should; but it is an unthankful, unhopeful spirit, that thinks and speaks of the dark side only. Oh, thou of little faith, wherefore didst thou doubt? The new life which Christ has brought into the world is a leaven too. Working on the same method, but backed by a mightier power, good will yet overcome evil,—life will destroy death. Life from the Lord and in the Lord, though small at first as to the number of persons whom it animates, will increase until it fill the world. It will absorb surrounding death, and in absorbing quicken it. He that sat upon the throne said, “Behold, I make all things new” (Rev. xxi. 5).
