Be not many masters. The common and almost universal interpretation of this passage is, that the Apostle discourages the desire for the office of teaching, and for this reason, because it is dangerous, and exposes one to a heavier judgment, in case he transgresses: and they think that he said, Be not many masters, because there ought to have been some. But I take masters not to be those who performed a public duty in the Church, but such as took upon them the right of passing judgment upon others: for such reprovers sought to be accounted as masters of morals. And it has a mode of speaking usual among the Greeks as well as Latins, that they were called masters who superciliously animadverted on others. And that he forbade them to be many, it was done for this reason, because many everywhere did thrust in themselves; for it is, as it were, an innate disease in mankind to seek reputation by blaming others. And, in this respect, a twofold vice prevails -- though few excel in wisdom, yet all intrude indiscriminately into the office of masters; and then few are influenced by a right feeling, for hypocrisy and ambition stimulate them, and not a care for the salvation of their brethren. For it is to be observed, that James does not discourage those brotherly admonitions, which the Spirit so often and so much recommends to us, but that immoderate desire to condemn, which proceeds from ambition and pride, when any one exalts himself against his neighbor, slanders, carps, bites, and malignantly seeks for what he may turn to a sinister purpose: for this is usually done when impertinent censors of this kind insolently boast themselves in the work of exposing the vices of others. From this outrage and annoyance James recalls us; and he adds a reason, because they who are thus severe towards others shall undergo a heavier judgment: for he imposes a hard law on himself, who tries the words and deeds of others according to the rule of extreme rigor; nor does he deserve pardon, who will pardon none. This truth ought to be carefully observed, that they who are too rigid towards their brethren, provoke against themselves the severity of God.

My brethren, be not many masters - "Be not many of you teachers." The evil referred to is that where many desired to be teachers, though but few could be qualified for the office, and though, in fact, comparatively few were required. A small number, well qualified, would better discharge the duties of the office, and do more good, than many would; and there would be great evil in having many crowding themselves unqualified into the office. The word here rendered "masters" (διδάσκαλοι didaskaloi) should have been rendered "teachers." It is so rendered in John 3:2; Acts 13:1; Romans 2:20; 1-Corinthians 12:28-29; Ephesians 4:11; 1-Timothy 2:11; 1-Timothy 4:3; Hebrews 5:12; though it is elsewhere frequently rendered master. It has, however, in it primarily the notion of "teaching" (διδάσκω didaskō), even when rendered "master;" and the word "master" is often used in the New Testament, as it is with us, to denote an instructor - as the "school-master."
Compare Matthew 10:24-25; Matthew 22:16; Mark 10:17; Mark 12:19, et al. The word is not properly used in the sense of master, as distinguished from a servant, but as distinguished from a disciple or learner. Such a position, indeed, implies authority, but it is authority based not on power, but on superior qualifications. The connection implies that the word is used in that sense in this place; and the evil reprehended is that of seeking the office of public instructor, especially the sacred office. It would seem that this was a prevailing fault among those to whom the apostle wrote. This desire was common among the Jewish people, who coveted the name and the office of "Rabbi," equivalent to that here used, (compare Matthew 23:7), and who were ambitious to be doctors and teachers. See Romans 2:19; 1-Timothy 1:7. This fondness for the office of teachers they naturally carried with them into the Christian church when they were converted, and it is this which the apostle here rebukes. The same spirit the passage before us would rebuke now and for the same reasons; for although a man should be willing to become a public instructor in religion when called to it by the Spirit and Providence of God, and should esteem it a privilege when so called, yet there would be scarcely anything more injurious to the cause of true religion, or that would tend more to produce disorder and confusion, than a prevailing desire of the prominence and importance which a man has in virtue of being a public instructor. If there is anything which ought to be managed with extreme prudence and caution, it is that of introducing men into the Christian ministry. Compare 1-Timothy 5:22; Acts 1:15-26; Acts 13:2-3.
Knowing that we shall receive the greater condemnation - (μεῖζον κρὶμα meizon krima. Or rather, "a severer judgment;" that is, we shall have a severer trial, and give a stricter account. The word here used does not necessarily mean "condemnation," but "judgment, trial, account;" and the consideration which the apostle suggests is not that those who were public teacher would be condemned, but that there would be a much more solemn account to be rendered by them than by other men, and that they ought duly to reflect on this in seeking the office of the ministry. He would carry them in anticipation before the judgment-seat, and have them determine the question of entering the ministry there. No better "stand-point" can be taken in making up the mind in regard to this work; and if that had been the position assumed in order to estimate the work, and to make up the mind in regard to the choice of this profession, many a one who has sought the office would have been deterred from it; and it may be added, also, that many a pious and educated youth would have sought the office, who has devoted his life to other pursuits. A young man, when about to make choice of a calling in life, should place himself by anticipation at the judgment-bar of Christ, and ask himself how human pursuits and plans will appear there. If that were the point of view taken, how many would have been deterred from the ministry who have sought it with a view to honor or emolument! How many, too, who have devoted themselves to the profession of the law, to the army or navy, or to the pursuits of elegant literature, would have felt that it was their duty to serve God in the ministry of reconciliation? How many at the close of life, in the ministry and out of it, feel, when too late to make a change, that they have wholly mistaken the purpose for which they should have lived!

Be not many masters - Do not affect the teacher's office, for many wish to be teachers who have more need to learn. There were many teachers or rabbins among the Jews, each affecting to have The truth, and to draw disciples after him. We find a caution against such persons, and of the same nature with that of St. James, in Pirkey Aboth, c. i. 10: Love labor, and hate the rabbin's office.
This caution is still necessary; there are multitudes, whom God has never called, and never can call, because he has never qualified them for the work, who earnestly wish to get into the priest's office. And of this kind, in opposition to St. James, we have many masters - persons who undertake to show us the way of salvation, who know nothing of that ways and are unsaved themselves. These are found among all descriptions of Christians, and have been the means of bringing the ministerial office into contempt. Their case is awful; they shall receive greater condemnation than common sinners; they have not only sinned in thrusting themselves into that office to which God has never called them, but through their insufficiency the flocks over whom they have assumed the mastery perish for lack of knowledge, and their blood will God require at the watchman's hand. A man may have this mastery according to the law of the land, and yet not have it according to the Gospel; another may affect to have it according to the Gospel, because he dissents from the religion of the state, and not have it according to Christ. Blockheads are common, and knaves and hypocrites may be found everywhere.

My (1) brethren, be not many masters, (2) knowing that we (a) shall receive the greater condemnation.
(1) The sixth part or place: Let no man usurp (as most men ambitiously do) authority to judge and censure others harshly. (2) A reason: Because they provoke God's anger against themselves, who do so eagerly and harshly condemn others, being themselves guilty and faulty.
(a) Unless we cease from this imperious and proud finding of fault with others.

My brethren, be not many masters,.... The apostle having dispatched the subject of faith and good works, which constitute the pure and undefiled religion mentioned in James 1:27 which gave rise to this discourse, he proceeds to consider the evidence of a religious man, suggested in James 1:26 who is one that bridles the tongue; and enters into an account of the use and abuse of the tongue: and which is introduced by this exhortation; and which seems to be opposed to an affectation among the Jews, to whom James writes, of being called "Rabbi, Rabbi", or "Mori, Mori", master, master, condemned by Christ, Matthew 23:8. The words may be rendered, "be not many teachers"; or be not fond, and forward, and ambitious of being preachers of the word, but rather choose to be hearers of it, agreeably to the advice in James 1:19, "be swift to hear, slow to speak"; not but that the office of a teacher is a good work, and a very desirable one; and spiritual gifts, qualifying for it, are to be coveted with a view to the glory of God, and the good of souls; and to have many teachers is a blessing to the churches of Christ and a large number of them is often not only proper, but absolutely necessary: but then this office should not be entered upon without suitable gifts, a divine mission, and a regular call by a church; and when entered into, should not be performed in a magisterial way, as lords over God's heritage, and as claiming a dominion over the faith of men, but as helpers of their joy, peace, and comfort; nor according to the commandments of men, but according to the oracles of God. Or it may be, this exhortation may have respect to censorious persons, rigid and severe reprovers of others, who take upon them, in a haughty manner, to charge and rebuke others for their faults; reproof for sin ought to be given; sin should not be suffered upon the brethren; to reprove is not blameworthy, but commendable, when it is done in a right manner, with a good spirit, and to a good end: in case of private offences, it should be privately given, and for public ones, men should be rebuked before all; but then this ought to be done in a gentle manner, and in a spirit of meekness; and when it is a clear case, and plain matter of fact, and which ought not to be exaggerated and aggravated; mole hills are not to be made mountains of, or a man be made an offender for a word, or a matter of human frailty; and reproof should be given by persons not guilty of the same, or worse crimes, themselves, and always with a good end; not to screen and cover their own vices, or to be thought more holy and religious than others, or to satisfy a revengeful spirit, but for the glory of God, and the restoring of the person that has sinned.
Knowing that we shall receive the greater condemnation: should men enter into the office of teaching others without a call, or perform it negligently, or live not according to the doctrine they teach others, such would be judged out of their own mouths, and by their own words, and their condemnation would be aggravated; and should men judge rash judgment, they themselves will be judged at a higher tribunal; and should they be too censorious, and bear too hard on others, they will have judgment without mercy.

We are taught to dread an unruly tongue, as one of the greatest evils. The affairs of mankind are thrown into confusion by the tongues of men. Every age of the world, and every condition of life, private or public, affords examples of this. Hell has more to do in promoting the fire of the tongue than men generally think; and whenever men's tongues are employed in sinful ways, they are set on fire of hell. No man can tame the tongue without Divine grace and assistance. The apostle does not represent it as impossible, but as extremely difficult. Other sins decay with age, this many times gets worse; we grow more froward and fretful, as natural strength decays, and the days come on in which we have no pleasure. When other sins are tamed and subdued by the infirmities of age, the spirit often grows more tart, nature being drawn down to the dregs, and the words used become more passionate. That man's tongue confutes itself, which at one time pretends to adore the perfections of God, and to refer all things to him; and at another time condemns even good men, if they do not use the same words and expressions. True religion will not admit of contradictions: how many sins would be prevented, if men would always be consistent! Pious and edifying language is the genuine produce of a sanctified heart; and none who understand Christianity, expect to hear curses, lies, boastings, and revilings from a true believer's mouth, any more than they look for the fruit of one tree from another. But facts prove that more professors succeed in bridling their senses and appetites, than in duly restraining their tongues. Then, depending on Divine grace, let us take heed to bless and curse not; and let us aim to be consistent in our words and actions.

DANGER OF EAGERNESS TO TEACH, AND OF AN UNBRIDLED TONGUE: TRUE WISDOM SHOWN BY UNCONTENTIOUS MEEKNESS. (James. 3:1-18)
be not--literally, "become not": taking the office too hastily, and of your own accord.
many--The office is a noble one; but few are fit for it. Few govern the tongue well (James 3:2), and only such as can govern it are fit for the office; therefore, "teachers" ought not to be many.
masters--rather, "teachers." The Jews were especially prone to this presumption. The idea that faith (so called) without works (James 2:14-26) was all that is required, prompted "many" to set up as "teachers," as has been the case in all ages of the Church. At first all were allowed to teach in turns. Even their inspired gifts did not prevent liability to abuse, as James here implies: much more is this so when self-constituted teachers have no such miraculous gifts.
knowing--as all might know.
we . . . greater condemnation--James in a humble, conciliatory spirit, includes himself: if we teachers abuse the office, we shall receive greater condemnation than those who are mere hearers (compare Luke 12:42-46). CALVIN, like English Version, translates, "masters" that is, self-constituted censors and reprovers of others James 4:12 accords with this view.

Be not many masters. Do not many of you seek to be teachers. The office of public teaching in the church is meant.
Shall receive the greater condemnation. Those who profess to teach others will be judged more strictly than those of humbler professions. Of those who have much, much is required. See Matthew 7:1. A lesson is to be given on the tongue. He who teaches will be held strictly to account for the manner in which he uses it.
For in many things. All are liable to stumble and make mistakes. These can hardly be excused in the teacher.
Same is a perfect man. He who controls his tongue gives proof of his ability to maintain entire self control.

Be not many teachers - Let no more of you take this upon you than God thrusts out; seeing it is so hard not to offend in speaking much. Knowing that we - That all who thrust themselves into the office. Shall receive greater condemnation - For more offences. St. James here, as in several of the following verses, by a common figure of speech, includes himself: we shall receive, - we offend, - we put bits, - we curse - None of which, as common sense shows, are to be interpreted either of him or of the other apostles.
