“The Kingdom of Heaven is like unto leaven which a man took, and hid in three measures of meal, till the whole was leavened - Matthew 13: 33.



In this short parable we have an example of a word* which, though it has a uniform rendering throughout the Bible, is yet, in one passage, generally taken in a sense which is exactly the opposite to all the others.


* There are practically two words, the noun and the verb: leaven; and to leaven.


This is not a question of translation, but of interpretation.  It is not a question of grammar, but of consistency.  It is in every passage translated “leaven”; but, while in some passages it is admittedly used in a bad sense, in others it is said to be doubtful; and in one passage, commentators, as a rule, agree in interpreting it in a good sense.



As this one passage is crucial to the interpretation of several parables, and has a most important practical bearing on the study of prophecy, it demands our careful consideration.



For, if leaven be understood here in a good sense, and the “church” substituted for the “kingdom,” then we have to look forward to the triumph of Christianity, and to its universal extension until it Christianises the whole earth.



If, on the other hand, leaven be understood in a bad sense, then, whether the Church be substituted for the Kingdom or not, we have to look forward to universal corruption and general apostasy.



It will be seen at once that the correct understanding of this word is vital to a true interpretation not merely of this particular parable, but of the whole prophetic teaching of the Word of God.  It is fundamental also to our whole practical Christian life.



For, if we hold the former to be true, we shall plunge into missionary work, and know nothing but this as our absorbing object; while the least we can do is to give up our lives, and if need be, our life, in this great cause.



On the other hand, it we hold the latter to be true, we shall be witnesses to the Saviour whom God has provided for lost sinners (Acts 1: 8); we shall “preach the Word; be instant in season and out of season” (2 Timothy 4: 2); but, we shall do this understandingly.  We shall not be lifted up with false hopes and vain expectations that men are going universally to receive it; but we shall preach the Word knowingly, being assured that “the time will come when men will not endure sound doctrine; but ... shall turn away their ears from the truth, and be turned unto fables” (2 Timothy 4: 3, 4).



So far from this being an incentive to idleness, it is revealed for the express purpose of inciting us to greater diligence; and is given as the very and only reason why we are to “preach the Word” with unceasing zeal.



It will be seen, therefore, that the true interpretation of the word “leaven” is fundamental and vital, not only to Christian doctrine, but to practical Christian service.



The truth will appear


I. From the meaning of the word “leaven”:


II. From its unvarying Biblical usage: and


III. From the uniform testimony of Prophetic teaching.




I. As to the meaning of the word “leaven” there seems to be much confusion and inexactness.  Probably, few Christians would be ready, off-hand, to answer the question, What is leaven?  This suggestion can be tested by asking the first Christian whom one may meet.  The answer, if correct, may be so, only “in part;” and in that case it will be incomplete.



Leaven, according to the dictionary, is “sour dough But this will not do for us.  We want to know why the dough should be sour? and how it became so.



To find this out, we have to avail ourselves of the latest scientific discoveries and definitions; using the word science in its true sense, as being scientia, i.e., what we know, and not what we think.



It is a matter of common knowledge, even among the most ignorant races of mankind, that many liquors under certain conditions develop a process which we call fermentation, by which certain gases are given off, and certain chemical changes take place.



To produce this, two things are necessary. viz., the presence of sugar, and exposure to the air.  The latter is essential; for apart from this there can be no fermentation, whatever may be the sweetness of the liquor.



This tells us that the primal cause is in the air.



Observation has shown that there are two great classes of microscopic organisms in the air, which are known as “germs” and “ferments  We must not call the former animal, and the latter vegetable, though this would give a rough idea of the difference.



The differences, though microscopic, are definite, and sufficiently distinct for the various organisms to receive names.  These “ferments” are microscopic cells not more than one hundredth of a millimetre in diameter, and are a species of fungi.  They multiply with incredible rapidity by sporulation, and budding; and not, as “germs” do, by fission and division.  They are in the air, everywhere perhaps; but yet by no means equally distributed.



On coming in contact with a medium suitable for their propagation, they at once begin to multiply (and can thus be artificially cultivated under control).  As the result of this action a scum rises to the surface of the liquor, which we call “yeast* The germs of the yeast plant abound in the atmosphere of breweries, and in vineyards, especially at the vintage season.**


* The English word “yeast” is the Anglo Saxon gist; German gascht or geist.  Hence our English gas, and gust (of wind), and ghost.  There may be a reference in this name to the working of some invisible power, like the “power of the air,” exciting internal motion, and producing the effect of foaming or frothing.


Our English word East and Easter may be associated with yeast, from the rising caused by it.


** Milk also ferments, from a smaller kind of microscopic fungus than vineous ferments, called Bacterium lutais, which are cylindrical.



A little of this “yeast on being put into dough, sets up fermentation in that; and changes it into a spongiform structure.  This arises chiefly from the presence of carbonic acid gas.*


* In the making of bread this gas is sometimes introduced artificially, by the use of aerated water or other devices, independently of yeast.  It is then known as “Aerated bread



If some of this dough, while in this condition, be put into fresh dough, fermentation will be at once set up, and the “ferments” will be propagated in this way: just as plants can be propagated from cuttings or slips, as well as from the original seeds.



It is this fermented dough, put aside for future use, that is called “leaven



A small piece of it is sufficient to reproduce the original fermentation throughout another mass of dough; so rapid is its growth and development.



In the case of grape-juice, the result, after the process of fermentation is completed, is what we know as wine. If fermentation has not taken place, it cannot rightly be called wine.*


* When it is bottled before the fermentation is complete we get “sparkling” wine, on account of some of the carbonic acid gas remaining in it.



In the case of dough it is different.  Nothing but the heat of the oven can stop the process of fermentation.  If it be not thus stopped, Bacteria would soon finish up the process and end it in putrefaction.*


* Even to in the case of the corruption in the kingdom and in the Church: false doctrine starts the process, and then the putrefactive Bacteria represent all the degradation that follows as a natural sequence when the leaven has done all it can.  Nothing but the fires of judgment will end it.  For this it waits.




II. We are now in a position to understand the Biblical usage of the word “leaven



In discovering this usage, all that is necessary for us to do is to look at every passage where it occurs; and see for ourselves, not what man says about it, but what God Himself teaches.



It there be any appropriateness in the symbols which God uses, and any connection between their nature and His lessons, then we have, already, a sufficient indication of what is likely to be His usage of the symbol of leaven.



We must not, however, allow ourselves to be biased by this, though we must give it its due weight, and be ready to receive its evidence.



If we carefully note every reference to leaven in the Bible, we find:-



1. That it is used of its natural characteristics and effects as permeating the entire mass into which it is introduced: never ceasing in its action until the whole has been affected by its influence.  This action is referred to in Matthew 13: 33; Luke 13: 21; 1 Corinthians 5: 6; Galatians 5: 9, and Hosea 7: 4.



2. Then it is used to describe the bread with which it is mixed; and we have the terms “leavened bread” and “unleavened bread  This is referred to in Exodus 12: 15, 19, 20, 34, 39; 13: 3, 7.



3. Next, it is used in connection with Sacrifices; and, by the Divine ordinance, leaven was never to be offered with any offering made by fire unto the Lord.* This is referred to in Leviticus 2: 11; 6: 17; 10: 12.


* “Honey” also was forbidden with the same limitation, because it is a cause of fermentation.  These two were only types; but their antitypes abound in the Hymn-books provided for our antitypical and spiritual “sacrifices of praise and thanksgiving  The leaven of false doctrine, and the honey of human sentiment, are everywhere to be found marring and defiling our Hymnology.  But “God Is not mocked,” and these sacrifices are not accepted.


In the case of the Peace-offering (not made by fire), when offered as a “sacrifice of thanksgiving,” it was to consist of “unleavened cakes:” but, beside the cakes, the offerer shall offer for HIS offering of “leavened bread with the sacrifice of thanksgiving of HIS peace offerings” (Leviticus 7: 12, 13).


This is a type of the evil which is inseparable from the sacrifices of praise and thanksgiving offered by human worshippers.



4. Then we have the New Testament usage; which has reference to its moral application; from which it will be seen that the matters which are compared to the working of leaven are so likened because of its material characteristics.



(a) Doctrine.



In Matthew 16: 12 “the doctrine of the Pharisees and of the Sadducees” is likened to leaven.



In Mark 8: 15 we are warned of “the leaven of the Pharisees, and of the leaven of Herod



In Luke 12: 1 we have “the leaven of the Pharisees, which is hypocrisy



In Galatians 5: 9 we have the doctrine of being “justified by the law” instead of by Christ, compared, in its working, to the action of leaven.



All these doctrines are evil; and are condemned.  There is no question about this; we have only to study these Scriptures to see why they are compared to leaven.  We need not enlarge upon them, beyond noting that -



In the doctrine of the Sadducees we have Materialism:



In Phariseeism, we have the doctrines of Plato, which are preserved in Traditional Psychology, and are the seeds of Spiritism.



In combination with the leaven of the Pharisees, which is hypocrisy- (i.e., the form without the power), we have “the leaven of Herod,” which is the same in its outward aspect; for Herod could be religious, and he “heard John gladly,” and “did many things” (Mark 6: 20); and yet, a little later, he could do one thing, for “he sent and beheaded John in the prison” (verse 27).  Even so is it to-day, with those who have only the “form of godliness without the power.”  They can flock to hear a preacher, and do many things; they have been leavened with “the leaven (or doctrine) of the Pharisees, and with the leaven of Herod.” (Compare Mark 4: 16, 17.)



(b) Practice.



Our association with evil-doers is compared to the fatal working of leaven: inasmuch as the danger of the whole lump’s being leavened by the presence of such is great. (Compare 1 Corinthians 15: 33.) The “old leaven” is to be purged out.  The whole of the context (1 Corinthians 5.) should be read, to understand the special instruction of verses 6-8.



5. Finally, we have the usage in three remaining passages in which the bad sense of the word is questioned, and a good sense is suggested, viz.:-


(a) Leviticus 23: 17,


(b) Amos 4: 4, 5.


(c) Matthew 13: 23.


(a) Leviticus 23: 15-17. “Ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete :.. Ye shall bring out of your habitations two wave loaves of two tenth deals: they shall be of fine flour; they shall be baken with leaven; they are the firstfruits unto the LORD



This is all explained to us in 1 Corinthians 15: 23: “Christ the first-fruits  This is “the wave sheaf” of Leviticus 23: 10-14.*


* The Septuagint has (harpage) first-fruit (verse 10).



“Afterward, they that are Christ’s at His coming  These are the “two wave loaves” of Leviticus 23: 15-21.*


* The Septuagint has (protogennema) first-begotten (verse 17).  This is a truly beautiful commentary; almost like an Inspiration.



“Then cometh the end  This is the “harvest” of verse 22.



We have the antitypes of these in the Gospels and Acts.  The first type, the wave sheaf, had been accomplished in the Resurrection of Christ.



Fifty days after the Resurrection began the fulfilment of the second type - in the proclamation to “Repent” (Acts 2: 38; 3: 19-26, R.V.); and in the then readiness of Christ to come.  Had that command to repent been obeyed, the promise made to them and to their children must have been fulfilled.  Christ’s promised coming would have been fulfilled in the sending of Jesus Christ.  In this case, “the first resurrection” must then have taken place.



But we know that Israel did not repent.  The two houses of the “men of Judah” and the “men of Israel” had both been called by Peter first separately (Acts 2: 14, 22) and then together (verse 36, “all the house of Israel”).  But they refused that call.  Hence the Kingdom, and the coming King, and the foretold “first resurrection” are all, in abeyance.



“All things are to be put under His feet” (1 Corinthians 15: 25).  But now, “we see not yet all things put under Him” (Hebrews 2: 8).



The type, however, is still true, and will one [millennial] day be verified in its antitype.



Now we can understand why there was to be leaven in those “two wave loaves  For, though they were made of the very flour of the first fruits: though Christ partook of the same nature, and was of the same seed of Abraham, yet He was “without sin” (Hebrews 4: 15); He “knew no sin” (1 Corinthians 5: 21); He “did no sin” (1 Peter 2: 22); “and in Him is no sin” (1 John 3: 5): yet, because the “two wave loaves” were the type of His earthly people who were all “under sin” (Romans 3: 9), and who cannot say “we have no sin” (1 John 1: 8), leaven is expressly ordered to be mixed, in order to make the type correspond with the antitype.



Not only is this the case, but with both the “wave sheaf” and the “two wave loaves” certain offerings were to be made.



But while, in the case of the “wave sheaf,” we have only two: “the burnt offering,” and “the meal offering with the drink offering thereof” (Leviticus 23: 12-14), yet, in the case of the “two wave loaves” we have four offerings:- the burnt offerings, “the meal offering and their drink offerings,” “the sin offering and “the peace offering” (verses 18-20).



Thus, beside the presence of sin in the people being typified by the presence of “leaven” in the “two wave loaves,” that sin was further shown to be there by the sin offering which is associated with them, though not with “the wave sheaf



This is conclusive as to Leviticus 23: 17.



(b) With regard to Amos 4: 4, 5.  This is either the language of irony; or it refers to the special form of peace offering, offered as a “thanksgiving with leaven prescribed in Leviticus 7: 14, as a type of the sin even in the thanksgiving of the offerer. (See note, above.)



(c) There remains only Matthew 13: 33.  Can it be believed that, in this one passage, the word “leaven” is used in the very opposite sense to that in which we find it in all the other passages?



And yet every commentator of repute, without any hesitation, would not only authorise us so to interpret it, but does not hesitate to bid us so to understand it.



But we cannot do so; no one has such authority, neither have we any such liberty.



The parable is usually read according to its punctuation, which is, of course entirely human and incorrect.  The parable does not say





unto leaven which a woman took, and hid in three measures of meal, till the whole was leavened



It is not merely the substance of “leaven or the initial act of the woman, but it is the whole process even up to the final leavening of the whole to which the Kingdom of heaven was likened.



In this the parable has its place, both in logical relationship, and in its doctrinal teaching, with the other parables with which it stands in immediate connection.



It is the last of the first four spoken to the multitude “out of the house” (verse 1), which have a common lesson, quite distinct from that of the last three, which were spoken to the disciples “in the house” (verse 34).*


* See The Kingdom and the Church, by the Editor.



In the first (the Sower), only one portion of the seed brought forth fruit; and there is no intimation as to the seed sown on the other three portions bringing forth any fruit.



In the second (the Tares), the “enemy” secretly sowed by night the seed of the tares.  These are “the children of the wicked one and they continue in the field, which is the world (cosmos), corrupting and defiling it, until the time of harvest, which is the end of the age (aion).



In the third (the Mustard Tree), we see “the fowls of the air” (the same evil creatures as in the first parable), finding a home in its branches.



In the fourth (the Leaven), we see the same corrupting influence at work, invisibly, like “ferments”; in contrast with what is visible, as in the preceding parable of the Tree.



Can we doubt that we have one and the same lesson in each of these four parables?



“The wicked one” in the first, limits the reception of the good seed.



The same power, the “enemy mixes his own seed with the children of the Kingdom.



The same power (for the fowls mean the wicked one, compare verse 4 with verse 19,) takes up his abode in the Kingdom (compare Revelation 18: 2).



It is therefore the same power that we see in the woman and her work.



The seed is sown not in the world, but only in four kinds of “ground” in it.



The seed, though sown in the world, has tares mixed with the whole of it.



The mustard tree is not the world, for it is only rooted in it.



So likewise it is not the world which is permeated by the leaven, but only the “meal” which is in it.



The Lord afterward repeated two of these parables (the Mustard Tree and the Leaven) in Luke 13: 18-21.  The occasion which called forth the repetition, marked by the word “then” (verse 18), shows that they were used to illustrate the increasing hostility of His enemies, which was the working of the leaven.



If the Lord, in His teaching, meant us to understand that the whole world was to be permeated with that which is good, He would have pictured to us (in the first) the seed everywhere producing fruit and the ground all “good  He would have spoken (in the second) of an unmixed field, sown only with good seed; or of the tares being changed into wheat.  He would have shown (in the third) a tree affording no shelter for unclean and hateful birds; and (in the fourth) some type other than leaven, seeing that the Holy Spirit in the Word, and He Himself in all His subsequent teaching, used it only of that which is evil.



Those who interpret the leaven as being typical of the Gospel do violence to the whole of these four parables as well as to the whole analogy of Bible truth.  For the Word is in no sense hidden, but is to be everywhere preached.  The Gospel is to be everywhere proclaimed with all boldness.  If the Gospel be hidden, it is the work of “the god of this world” (2 Corinthians 4: 3, 4).




III. Only a few words are necessary to show how all this agrees with the unvarying testimony of Prophetic teaching.



Everywhere are we warned of judgment to come; of dark days and “perilous times” (2 Timothy 3: 1); of “evil men, and deceivers waxing worse and worse” (2 Timothy 3: 13); of “departure from the Faith” (1 Timothy 4: 1); of “scoffers walking after their own lusts” (2 Peter 3: 3); of the coming “apostasy” and the revelation of “the man of sin” (2 Thessalonians 2: 3).  Everywhere are we warned against the spread of doctrinal corruption, and of fleshly lusts.



Instead of being told that the world is not good enough for the coming of Christ, we are told that it is not bad enough.  Instead of being told that He will not appear until the world’s conversion comes, we are told that it will not be until the apostasy shall have come (2 Thessalonians 2: 3). 



Instead of the Church overcoming the world, we see before our very eyes that the world is fast overcoming the Church.



Truly the leaven is working in the Church as well, as it has worked, and will ere long again work, in the Kingdom.



For the prophecies and the parables of the Kingdom leap over this present Church interval, and continue its history as though the Church had no existence.  And the work of this leaven is only evil.



Our attitude, therefore, now, toward God and His sure word of prophecy; toward man, the Church, and the world is entirely dominated by the sense in which we understand the Bible use of the word “leaven*  This will be a sufficient reason for our having devoted so much space to the consideration of the subject.












Dr. Parsons, in his Development of Antichrist, says:



“The Parable of the Leaven represents the results which will be manifested in the kingdom of Christ during the age from the corruptions introduced by those within ‘the church.’  The meal will be leavened by heresies and perversions during all this dispensation.



“All the parables of Christ illustrating the mystery of the administration of His kingdom plainly betoken a mixed and corrupted state of things to the end of this dispensation, and the Spirit confirms this in the revelation of this great apostasy:



“‘Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; speaking lies in hypocrisy; having their conscience seared with a hot iron; forbidding to marry, and commanding to abstain from meats, which God hath created to he received with thanksgiving of them which believe and know the truth.’ - 1 Tim. 4: 1-3.



“Also that times of great peril shall be in the last days; that formality and hypocrisy will abound; that all who adhere to godliness shall suffer persecution; and that evil men and seducers shall wax worse and worse, deceiving and being deceived.”
