QUESTIONS: 

1]
What does this phrase mean?
2] What is Matthew 7:15-20 about?
3] What does "fruit" mean?
4] Who is "them"?

ANSWER:

I was prompted to write this Bible study after visiting a Church of God chat room which is open to members of multiple COG organizations.  The subject of Matthew 7 and this phrase became a topic of discussion.  I explained both the verse and the phrase but was then greeted with a number of contrary opinions as to the meaning of, "By their fruits you shall know them."  Most believed that you can know people by their actions, including good works and sin.  If the person shows good works, they conclude he or she is in the faith and if they sin or have a life laced in sinful behavior, they must be evil.  However, we are about to see overwhelming proof the meaning is somewhat different.

Let us begin by reading the entire passage:

Matthew 7:15-20
15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
20 Wherefore by their fruits ye shall know them.

First of all...

  Question Answer/Conclusion
1]  In verse 20, it says we shall know them.  Who are "them"? True and false prophets (by extension, ministers).

Notice a commentary:

Matthew 7:15
[False prophets] The word prophet originally means one who foretells future events. As prophets, however, were commonly regarded as public instructors on the subject of religion, the word came to denote all who were religious teachers.
(from Barnes' Notes)
 
2] What is the primary function of ministers? Preaching and teaching the Word of God.
 
3] What does the word, "fruit" mean in this passage? First and foremost, it means "doctrine".  That is, what the minister teaches and preaches.  A good minister is in "close adherence" to scripture.  An evil or false minister is not.  He preaches false doctrine and things contrary to God.
 
4] Could "fruit" also mean actions and behavior? Only to a minor degree as we will soon see.
 
5] Could "fruit" mean "sin"? No.  This passage is about identifying both true and false ministers, that is, knowing the difference.  "Fruit" cannot have a primary meaning of sin as both true and false ministers sin and are subject to sin.  Clearly, false preaching is sin, but this fact is a given.  We are not looking for a false minister to sin, we are focused on what he is preaching and teaching...false doctrines.
 
6] How do we know this to be true, that "fruit" cannot mean sin? The proof is contained in verses 17 and 18.  A good tree brings forth good fruit.  A bad tree brings forth bad fruit.  A good tree cannot bring forth bad fruit and a bad tree cannot bring forth good fruit.

Can a good minister sin?  Of course he can.
Can a good minister demonstrate bad or offensive behavior?  Yes.
Can a false minister demonstrate good or righteous behavior?  Yes

If the primary meaning of "fruit" was sin or good and bad behavior, verses 17-18 would not make any sense.   The primary meaning of "fruit" as true or false doctrine fits perfectly.
 
7] What other indication do we have to show the meaning of "fruit" is not sin and/or bad behavior? This is found in verse 15 and the mention of "sheep's clothing".  This is a clear indication of deception on the part of the false minister.  He appears righteous and pleasing to the unsuspecting member.  Therefore, by definition, we cannot claim to say we can always identify a false minister based solely on observed behavior.

Behavior vs. Doctrine & Scripture

Which is the purer science, verifying the behavior or the doctrine of the false minister?  Which identification is faster?  Fact is, behavior can be used to deceive.  However, one cannot truly fake doctrine.  Doctrine is either true or false.  If one is immersed in the Word of God, he or she can readily know false doctrine when they see or hear it.

What do the commentaries and other Bible helps tell us?

Reference Commentary/Explanation
Wycliffe Bible Commentary Matt 7:15-20
By their fruits. The doctrines produced by these false prophets, rather than the works they perform, since outward appearances may not cause suspicion. The test of the prophet is his conformity to Scripture (1 Cor 14:37; Deut 13:1-5). -end quote-(emphasis mine)

1 Corinthians 14:37
37 If any man think himself to be a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandments of the Lord.

Deuteronomy 13:1-5
13:1 If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder,
2 And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them;
3 Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul.
4 Ye shall walk after the LORD your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him.
5 And that prophet, or that dreamer of dreams, shall be put to death; because he hath spoken to turn you away from the LORD your God, which brought you out of the land of Egypt, and redeemed you out of the house of bondage, to thrust thee out of the way which the LORD thy God commanded thee to walk in. So shalt thou put the evil away from the midst of thee.


Clearly speaking to the words of the prophet, not his actions or behavior.
 
Nelson's new illustrated Bible commentary 7:15–20 Beware of false prophets: Deuteronomy 13:1–11; 18:20–22 provide information on discerning and responding to false prophets. The way to tell false teachers from teachers of truth is by their fruits. Fruits here refers to more than their deeds; it includes their doctrine (16:12; 1 John 4:1–3). A person speaking in the name of God is to be tested by the doctrines of Scripture. The same principle still holds true today. Speakers and teachers should be tested against the truths in God’s Word (Jude 3; Rev. 22:18, 19). -end quote-(emphasis mine)

This commentary is massively clear:  Ministers are to be tested and verified by SCRIPTURE.
 
Believer's Bible Commentary 7:16–18 Verses 16–18 deal with the detection of the false prophets: you will know them by their fruits. Their licentious lives and destructive teachings betray them. A tree or plant produces fruit according to its character. Thornbushes cannot bear grapes; thistles do not bear figs. A good tree bears good fruit and a bad tree bears bad fruit. This principle is true in the natural world and in the spiritual world. The life and teaching of those who claim to speak for God should be tested by the Word of God: “If they do not speak according to this word, it is because there is no light in them” (Isaiah 8:20).  --end quote--(emphasis mine)

Using scripture as the indicator trumps observed behavior.
 
KJV Bible Commentary 16–20. A true test of a prophet was the conformity of his doctrine to that of the Scripture (cf. 1 Corinthians 14:37; Deuteronomy 13:1–5). Their fruits not only refer to actions of their lives, for these men are very, very sheepish, but to the doctrines which they proclaim. Having warned us against falsely judging others, Jesus now must remind us to beware and know such people. We are to be discerning enough not to be taken in by their cleverness. --end quote--(emphasis mine)

Another verification we are talking about doctrine and scripture as the chief test.

 

Matthew Henry's Commentary False apostles are those who say they are apostles, and are not (Revelation 2:2); such are false prophets. "Take heed of those who pretend to revelation, and admit them not without sufficient proof, lest that one absurdity being admitted, a thousand follow.’’  --end quote--

Clearly the sufficient proof comes from comparing their teaching to scripture.
 
Nelson's illustrated Manners & Customs of the Bible Jesus often used agricultural symbols in His teaching. He described a sower scattering his seed (Mark 4:1–20) and laborers who answered a call to work in a vineyard (Matthew 20:1–16). He compared false prophets to trees that bear bad fruit (Matt. 7:15–20) and warned that “every tree is known by his own fruit” (Luke 6:43–44). Jesus promised to give His followers “living water” from everlasting wells (John 4). He used seeds, vines, trees, fruit, and other agricultural metaphors to express the truths of God. --end quote-- (emphasis mine)

As this Bible help states, fruit is a metaphor to express the truths of God, i.e., The Word of God.

 

KJV Bible Commentary

The two alternatives: Character established. 7:13–27.

The closing section of the Sermon on the Mount presents two choices to the listener. These are presented in a series of contrasts: two ways (vss. 13–14); two trees (vss. 15–20); two professions (vss. 21–23); and two foundations (vss. 24–29). This was a common method of teaching in both Jewish and Greco-Roman thought.

15. The warning of Beware of false prophets fits appropriately with the concept of the two ways. Since many are being misled in the wrong way, it is obvious that they are being misled by wrong ones. False prophets were prevalent in the Old Testament, whereas God’s true prophets were often in the minority (as in Elijah’s confrontation with the prophets of Baal). These appear in sheep’s clothing but are in reality ravening wolves. This is a perfect description of those preachers who have denied or distorted the truth of the gospel. They look like a lamb but they act like a wolf. Their description is similar to that of the great false prophet in Revelation 13:11. --end quote--(emphasis mine)

We see clearly here that false ministers use deception by masking their heart and evil agenda by demonstrating fruits of the Spirit--appearance of light.  The commentary states plainly that the key is distorted truth of the gospel.  If we are immersed in the Word of God, we readily recognize the distortion.
 

The meaning is very clear:

1] These scriptures concern the identification of true and false ministers.
2] This is accomplished, first and foremost, by testing what they teach and preach.
3] Actions and Christian behavior can be used to deceive.
4] Despite the use of Slick Arguments, one cannot fake the Word of God.

Sheep's clothing

Let us go back to the Bible commentaries and focus on Sheep's clothing.  Those in opposition to the proof above will maintain that these scriptures, in no way, are speaking to the doctrine or teachings of the false minister.  Rather, they argue that you identify them by their behavior alone.  What do the commentaries say?
 

Reference Commentary/Explanation
The Key Verse Matthew 7:15
Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
 
Wycliffe Bible Commentary
Sheep's clothing is not to be regarded as prophets' grab, but is an evident contrast to vicious wolves. God's people in all ages have needed to beware of deceptive leaders (Deuteronomy 13:1; Acts 20:29; 1 John 4:1; Revelation 13:11-14). --end quote--

Now the scriptures made reference to:

Deuteronomy 13:1
13:1 If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder,

Acts 20:29
29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.

1 John 4:1
4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.

Revelation 13:11-14
11 And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon.
12 And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed.
13 And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men,
14 And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.

Besides behavior, these scriptures state that false individuals will use lying wonders to fool you.  Are miracles and wonders absolute proof one is of God?  OF COURSE NOT.
 
Barnes Notes [commentary] Matthew 7:15
[Who come in sheep's clothing] The sheep is an emblem of innocence, sincerity, and harmlessness. To come in sheep's clothing is to assume the appearance of sanctity and innocence, when the heart is evil. --end quote--

Clearly behavior is being used as the element of deception.  Notice that nothing is said of the Word of God being used as an element of deception.
 
Adam Clarke's Commentary Matthew 7:15
[Beware of false prophets] By false prophets we are to understand teachers of erroneous doctrines, who come professing a commission from God, but whose aim is not to bring the heavenly treasure to the people, but rather to rob them of their earthly good. Teachers who preach for hire, having no motive to enter into the ministry but to get a living, as it is ominously called by some, however they may bear the garb and appearance of the innocent useful sheep, the true pastors commissioned by the Lord Jesus, or to whatever name, class, or party they may belong, are, in the sight of the heart-searching God, no other than ravenous wolves, whose design is to feed themselves with the fat, and clothe themselves with the fleece and thus ruin, instead of save, the flock. --end quote-- (emphasis mine)

They appear as innocent useful sheep - ministers of Jesus Christ.  They fool by behavior.
 
Believer's Bible Commentary 7:15 Wherever the stern demands of true discipleship are taught, there are false prophets who advocate the wide gate and easy way. They water down the truth until, as C. H. Spurgeon said, “There is not enough left to make soup for a sick grasshopper.” These men who profess to be speaking for God come in sheep’s clothing, giving the appearance of being true believers. --end quote-- (emphasis mine)

This is the element they use to fool the firstfruits--behavior.
 
KJV Bible Commentary These appear in sheep’s clothing but are in reality ravening wolves. This is a perfect description of those preachers who have denied or distorted the truth of the gospel.  --end quote--

They give "appearance" of sheep.  Therefore, how can this be the chief means of identification when the commentary clearly states these false ministers are distorting the truth?
 

This makes it very clear that appearance, conduct, behavior and words spoken in fellowship are not the best indicators of false ministers, as this is the element they use to deceive.  Again, the best element in this case [identifying false ministers] is testing their doctrine against the Word of God.

REBUTTAL

Now some might come forth with Proverbs 20:11 or similar scripture to counter everything said so far.  Notice the verse:

Proverbs 20:11
Even a child is known by his doings, whether his work be pure, and whether it be right.

Matthew 7:15-20 is speaking to the identification of a specific set of individuals, true and false ministers.  What is the chief "doing" or action of the minister?  Clearly it is his preaching and doctrine. 

God made this scripture specific for the simple fact all of the congregation interacts with the ministry.  That point of interaction is teaching and doctrine.  In fact, depending upon the situation, the lion's share of contact the member has with the ministry is the sermon and Bible study.  This is why God give the specific admonition to prove each minister based on his doctrine and preaching.  Jesus said much about false ministers:

Matthew 24:4-5
4 And Jesus answered and said unto them, Take heed that no man deceive you.
5 For many shall come in my name, saying, I am Christ; and shall deceive many.

Matthew 24:11
11 And many false prophets shall rise, and shall deceive many.

Matthew 24:24-25
24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
25 Behold, I have told you before.

All these verses are from Matthew 24 when Jesus was answering the questions of what the end time would be like.  What verses do we see here of our fellow brother in the faith being false or even fallen away?  Except when a brother is openly sinning without repentance, what are the chances of you even knowing the true nature of your brother or having his negative character bringing you down?  Far less than being influenced by false doctrine to be sure.  We see this clearly indicated in Jesus prophecy of Matthew 24 and 25.

Matthew 24:40-41
40 Then shall two be in the field; the one shall be taken, and the other left.
41 Two women shall be grinding at the mill; the one shall be taken, and the other left.

Matthew 25:1-2
1 Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom.
2 And five of them were wise, and five were foolish.

This is clear indication that some of  those fallen from the faith will be with the faithful right up to the return of Christ.  Notice the faithful remaining faithful despite any possible influence of the fallen away.  Why?  Because they stayed in the Salvation Process and allowed no person to take their crown.  Christ, knowing the situation, saw the greatest threat not from a brother in the faith so much as false ministers and those spreading false doctrines in the form of slick arguments [spoken or in text].

So heed the words of Jesus and know the difference between true and false ministers.

To the law and to the testimony: if they speak not according to this word, it is because there is no light in them. –Isaiah 8:20
