Here the apostle instructs Timothy how to guard against the judaizing teachers, or others who mingled fables and endless genealogies with the gospel. He shows the use of the law, and the glory of the gospel.

I.He shows the end and uses of the law: it is intended to promote love, for love is the fulfilling of the law, Rom 13:10.

1.The end of the commandment is charity, or love, Rom 13:8. The main scope and drift of the divine law are to engage us to the love of God and one another; and whatever tends to weaken either our love to God or love to the brethren tends to defeat the end of the commandment: and surely the gospel, which obliges us to love our enemies, to do good to those who hate us (Mat 5:44) does not design to lay aside or supersede a commandment the end whereof is love; so far from it that, on the other hand, we are told that though we had all advantages and wanted charity, we are but as sounding brass and a tinkling cymbal, Co1 13:1. By this shall all men know that you are my disciples, if you love one another, Joh 13:35. Those therefore who boasted of their knowledge of the law, but used it only as a colour for the disturbance that they gave to the preaching of the gospel (under pretence of zeal for the law, dividing the church and distracting it), defeated that which was the very end of the commandment, and that is love, love out of a pure heart, a heart purified by faith, purified from corrupt affections. In order to the keeping up of holy love our hearts must be cleansed from all sinful love; our love must arise out of a good conscience, kept without offence. Those answer the end of the commandment who are careful to keep a good conscience, from a real belief of the truth of the word of God which enjoins it, here called a faith unfeigned. Here we have the concomitants of that excellency grace charity; they are three: - (1.) A pure heart; there it must be seated, and thence it must take its rise. (2.) A good conscience, in which we must exercise ourselves daily, that we may not only get it, but that we may keep it, Act 24:16. (3.) Faith unfeigned must also accompany it, for it is love without dissimulation: the faith that works by it must be of the like nature, genuine and sincere. Now some who set up for teachers of the law swerved from the very end of the commandment: they set up for disputers, but their disputes proved vain jangling; they set up for teachers, but they pretended to teach others what they themselves did not understand. If the church be corrupted by such teachers, we must not think it strange, for we see from the beginning it was so. Observe, [1.] When persons, especially ministers, swerve from the great law of charity - the end of the commandment, they will turn aside to vain jangling; when a man misses his end and scope, it is no wonder that every step he takes is out of the way. [2.] Jangling, especially in religion, is vain; it is unprofitable and useless as to all that is good, and it is very pernicious and hurtful: and yet many people's religion consists of little else but vain jangling. [3.] Those who deal much in vain jangling are fond and ambitious to be teachers of others; they desire (that is, they affect) the office of teaching. [4.] It is too common for men to intrude into the office of the ministry when they are very ignorant of those things about which they are ton speak: they understand neither what they say nor whereof they affirm; and by such learned ignorance, no doubt, they edify their hearers very much!

2.The use of the law (Ti1 1:8): The law is good, if a man use it lawfully. The Jews used it unlawfully, as an engine to divide the church, a cover to the malicious opposition they made to the gospel of Christ; they set it up for justification, and so used it unlawfully. We must not therefore think to set it aside, but use it lawfully, for the restraint of sin. The abuse which some have made of the law does not take away the use of it; but, when a divine appointment has been abused, call it back to its right use and take away the abuses, for the law is still very useful as a rule of life; though we are not under it as under a covenant of works, yet it is good to teach us what is sin and what is duty. It is not made for a righteous man, that is, it is not made for those who observe it; for, if we could keep the law, righteousness would be by the law (Gal 3:21): but it is made for wicked persons, to restrain them, to check them, and to put a stop to vice and profaneness. It is the grace of God that changes men's hearts; but the terrors of the law may be of use to tie their hands and restrain their tongues. A righteous man does not want those restraints which are necessary for the wicked; or at least the law is not made primarily and principally for the righteous, but for sinners of all sorts, whether in a greater or less measure, Ti1 1:9, Ti1 1:10. In this black roll of sinners, he particularly mentions breaches of the second table, duties which we owe to our neighbour; against the fifth and sixth commandments, murderers of fathers and mothers, and manslayers; against the seventh, whoremongers, and those that defile themselves with mankind; against the eighth, men-stealers; against the ninth, liars and perjured persons; and then he closes his account with this, and if there be any other thing that is contrary to sound doctrine. Some understand this as an institution of a power in the civil magistrate to make laws against such notorious sinners as are specified, and to see those laws put in execution.

II.He shows the glory and grace of the gospel. Paul's epithets are expressive and significant; and frequently every one is a sentence: as here (Ti1 1:11), According to the glorious gospel of the blessed God. Let us learn hence, 1. To call God blessed God, infinitely happy in the enjoyment of himself and his own perfections. 2. To call the gospel the glorious gospel, for so it is: much of the glory of God appears in the works of creation and providence, but much more in the gospel, where it shines in the face of Jesus Christ. Paul reckoned it a great honour put upon him, and a great favour done him, that this glorious gospel was committed to his trust; that is, the preaching of it, for the framing of it is not committed to any man or company of men in the world. The settling of the terms of salvation in the gospel of Christ is God's own work; but the publishing of it to the world is committed to the apostles and ministers. Note here, (1.) The ministry is a trust, for the gospel was committed unto this apostle; it is an office of trust as well as of power, and the former more than the latter; for this reason ministers are called stewards, Co1 4:1. (2.) It is a glorious trust, because the gospel committed to them is a glorious gospel; it is a trust of very great importance. God's glory is very much concerned in it. Lord, what a trust is committed to us! How much grace do we want, to be found faithful in this great trust!

Teachers of the law - To be esteemed or celebrated as rabbins; to be reputed cunning in solving knotty questions and enigmas, which answered no end to true religion. Of such the rabbinical teaching was full.

Understanding neither what they say - This is evident from almost all the Jewish comments which yet remain. Things are asserted which are either false or dubious; words, the import of which they did not understand, were brought to illustrate them: so that it may be said, They understand not what they say, nor whereof they affirm. I will give one instance from the Jerusalem Targum, on Gen 1:15 : And God made two great lights, and they were equal in splendor twenty-one years, the six hundred and seventy-second part of an hour excepted: and afterwards the moon brought a false accusation against the sun, and therefore she was lessened; and God made the sun the greater light to superintend the day, etc. I could produce a thousand of a similar complexion.

Desiring to be teachers of the law,.... They were very fond of being called Rabbi, Rabbi, and styled doctors of the law, and of being thought to have skill in interpreting the law, and good talents in expounding it, and preaching upon it; which was now most in vogue, and gained the greatest applause, when the preaching of the Gospel was treated with contempt, not only by the unbelieving Jews, but by judaizing Christians, and carnal professors,

Understanding neither what they say, nor whereof they affirm: they did not understand the law, the nature and end, the purity and spirituality, and perfection of it, which they were so fond of teaching, and went into many foolish and unlearned questions about it; see Ti2 2:23, and which they as foolishly answered: these are the ignorant and unlearned men, who, notwithstanding their vain show of learning, and pretence to skill in interpreting the law, wrested the Scriptures to their own destruction, and that of others; they were ignorant of the things they talked of, and knew not by what arguments to confirm them, and yet were very bold and confident in their assertions: and generally speaking so it is, that those who can prove least assert most, and that with the greatest assurance.

Sample of their "vain talk" (Ti1 1:6).

Desiring--They are would-be teachers, not really so.

the law--the Jewish law (Tit 1:14; Tit 3:9). The Judaizers here meant seem to be distinct from those impugned in the Epistles to the Galatians and Romans, who made the works of the law necessary to justification in opposition to Gospel grace. The Judaizers here meant corrupted the law with "fables," which they pretended to found on it, subversive of morals as well as of truth. Their error was not in maintaining the obligation of the law, but in abusing it by fabulous and immoral interpretations of, and additions to, it.

neither what they say, nor whereof--neither understanding their own assertions, nor the object itself about which they make them. They understand as little about the one as the other [ALFORD].
