Hast thou faith? In order to conclude, he shows in what consists the advantage of Christian liberty: it hence appears, that they boast falsely of liberty who know not how to make a right use of it. He then says, that liberty really understood, as it is that of faith, has properly a regard to God; so that he who is endued with a conviction of this kind, ought to be satisfied with peace of conscience before God; nor is it needful for him to show before men that he possesses it. It hence follows, that if we offend our weak brethren by eating meats, it is through a perverse opinion; for there is no necessity to constrain us. It is also plainly evident how strangely perverted is this passage by some, who hence conclude, that it is not material how devoted any one may be to the observance of foolish and superstitious ceremonies, provided the conscience remains pure before God. Paul indeed intended nothing less, as the context clearly shows; for ceremonies are appointed for the worship of God, and they are also a part of our confession: they then who tear off faith from confession, take away from the sun its own heat. But Paul handles nothing of this kind in this place, but only speaks of our liberty in the use of meat and drink. Happy is he who condemns not himself, etc. Here he means to teach us, first, how we may lawfully use the gifts of God; and, secondly, how great an impediment ignorance is; and he thus teaches us, lest we should urge the uninstructed beyond the limits of their infirmity. But he lays down a general truth, which extends to all actions, -- "Happy," he says, "is he who is not conscious of doing wrong, when he rightly examines his own deeds." For it happens, that many commit the worst of crimes without any scruple of conscience; but this happens, because they rashly abandon themselves, with closed eyes, to any course to which the blind and violent intemperance of the flesh may lead them; for there is much difference between insensibility and a right judgment. He then who examines things is happy, provided he is not bitten by an accusing conscience, after having honestly considered and weighed matters; for this assurance alone can render our works pleasing to God. Thus is removed that vain excuse which many allege on the ground of ignorance; inasmuch as their error is connected with insensibility and sloth: for if what they call good intention is sufficient, their examination, according to which the Spirit of God estimates the deeds of men, is superfluous.

Footnotes

1 - The version of Calvin is, "Beatus qui non judicat seipsum in eo quod examinat," makarios ho me krinon heauton en o dokimazei; the latter part is rendered by Beza, and Piscator, "in eo quod approbat -- in that which he approves;" by Doddridge, "in the thing which he alloweth;" by Macknight, "by what he approveth." The reference is no doubt to the strong, who had "faith," who believed all meats lawful. The verb means to try, to examine, as well as to approve; but the latter seems to be its meaning here. To approve and to have faith appears in this case to be the same: then to have faith and not to abuse it by giving offense to a brother was to be a happy man, who did not condemn himself. The meaning then most suitable to the passage is this, "Happy the man! who condemns not himself by what he approves," that is, by eating meat to the annoyance and stumbling of the weak. -- Ed.

Hast thou faith? - The word "faith" here refers only to the subject under discussion - to the subject of meats, drinks, etc. Do you believe that it is right to eat all kinds of food, etc. The apostle had admitted that this was the true doctrine; but he maintains that it should be so held as not to give offence.
Have it to thyself - Do not obtrude your faith or opinion on others. Be satisfied with cherishing the opinion, and acting on it in private, without bringing it forward to produce disturbance in the church.
Before God - Where God only is the witness. God sees your sincerity, and will approve your opinion. That opinion cherish and act on, yet so as not to give offence, and to produce disturbance in the church. God sees your sincerity; he sees that you are right; and you will not offend him. Your brethren do "not" see that you are right, and they will be offended.
Happy is he - This state of mind, the apostle says, is one that is attended with peace and happiness; and this is a "further" reason why they should indulge their opinion in private, without obtruding it on others. They were conscious of doing right, and that consciousness was attended with peace. This fact he states in the form of a universal proposition, as applicable not only to "this" case, but to "all" cases; compare 1-John 3:21.
Condemneth not himself - Whose conscience does not reprove him.
In that which he alloweth - Which he "approves," or which he "does." Who has a clear conscience in his opinions and conduct. Many people indulge in practices which their consciences condemn, many in practices of which they are in doubt. But the way to be happy is to have a "clear conscience" in what we do; or in other words, if we have "doubts" about a course of conduct, it is not safe to indulge in that course, but it should be at once abandoned. Many people are engaged in "business" about which they have many doubts; many Christians are in doubt about certain courses of life. But they can have "no doubt" about the propriety of abstaining from them. They who are engaged in the slave-trade; or they who are engaged in the manufacture or sale of ardent spirits; or they who frequent the theater or the ball-room, or who run the round of fashionable amusements, if professing Christians, must often be troubled with "many" doubts about the propriety of their manner of life. But they can have no doubt about the propriety of an "opposite" course. Perhaps a single inquiry would settle all debate in regard to these things: "Did anyone ever become a slave-dealer, or a dealer in ardent spirits, or go to the theater, for engage in scenes of splendid amusements, with any belief that he was imitating the Lord Jesus Christ, or with any desire to honor him or his religion?" But one answer would be given to this question; and in view of it, how striking is the remark of Paul, "Happy is he that condemneth not himself in what he alloweth."

Hast thou faith? - The term faith seems to signify in this place a full persuasion in a man's mind that he is right, that what he does is lawful, and has the approbation of God and his conscience. Dr. Taylor has a judicious note on this passage. "There is no necessity," says he, " for reading the first clause interrogatively; and it seems to be more agreeable to the structure of the Greek to render it, Thou hast faith; as if he had said: 'I own thou hast a right persuasion.' Farther, there is an anadiplosis in εχεις, and εχε the first simply signifies thou hast, the latter, hold fast. Thou hast a right persuasion concerning thy Christian liberty; and I advise thee to hold that persuasion steadfastly, with respect to thyself in the sight of God. Εχω have, has frequently this emphatical signification. See Matthew 25:29, etc."
Happy is he that condemneth not, etc. - That man only can enjoy peace of conscience who acts according to the full persuasion which God has given him of the lawfulness of his conduct: whereas he must be miserable who allows himself in the practice of any thing for which his conscience upbraids and accuses him. This is a most excellent maxim, and every genuine Christian should be careful to try every part of his conduct by it. If a man have not peace in his own bosom, he cannot be happy; and no man can have peace who sins against his conscience. If a man's passions or appetite allow or instigate him to a particular thing, let him take good heed that his conscience approve what his passions allow, and that he live not the subject of continual self-condemnation and reproach. Even the man who has the too scrupulous conscience had better, in such matters as are in question, obey its erroneous dictates than violate this moral feeling, and live only to condemn the actions he is constantly performing.

(19) Hast thou (q) faith? have [it] to thyself before God. Happy [is] he that condemneth not himself in that thing which he (r) alloweth.
(19) He gives a double warning in these matters: one, which pertains to the strong, that he who has obtained a sure knowledge of this liberty, keep that treasure to the end that he may use it wisely and profitably, as has been said: the second, which respects the weak, that they do nothing rashly by other men's example with a wavering conscience, for it cannot be done without sin if we are not persuaded by the word of God that he likes and approves it.
(q) He showed before in (Romans 14:14) what he means by faith, that is, for a man to be certain and without doubt in matters and things indifferent.
(r) Embraces.

Hast thou faith? have it to thyself before God,.... Which is to be understood, not of faith in the Lord Jesus Christ, and in the doctrines of the Gospel; for a man that has such faith given him, ought not to keep it in his own breast, but to declare it to others; he ought to make a public visible profession of it, before many witnesses; it becomes him to tell the church of God what great things the Lord has done for him; and as he believes with the heart, so he ought to make confession with the mouth unto salvation; but this faith only designs a full persuasion in a man's own mind, about the free and lawful use of things indifferent, the subject the apostle is upon; see Romans 14:5; and his advice on this head is, to keep this faith and persuasion in a man's own breast, and not divulge it to others, where there is danger of scandal and offence: he does not advise such to alter their minds, change their sentiments, or cast away their faith, which was right and agreeable to his own, but to have it, hold and keep it, though, within themselves; he would not have them openly declare it, and publicly make use of it, since it might be grieving and distressing to weak minds; but in private, and where there was no danger of giving offence, they might both speak of it, and use it; and if they could not, should satisfy themselves that God, who sees in secret, knows they have this faith, and sees their use of it, though others do not, for from him they have it; so the Ethiopic version reads it, and "if thou hast faith with thyself, thou art secure before God, from whom thou hast obtained it"; and should be thankful to him for it, and use it in such a manner as makes most for his glory, and the peace of his church since to him they must give an account another day: some copies and versions read without an interrogation, thou hast faith; and others, "thou, the faith which thou hast, have it to thyself", &c. so the Alexandrian copy and the Syriac version.
Happy is he that condemneth not himself in that thing which he alloweth; or "approves of"; that is, it is well for that man who observes no difference of meats, if either he does not act contrary to his own conscience, and so condemns himself in what he allows himself in; or exposes himself to the censure, judgment, and condemnation of others, in doing that which he approves of as lawful, and is so, but unlawful when done to the offence of others: some understand this as spoken to the weak believer, signifying that he is in the right, who, through example, and the force of the sensual appetite, is not prevailed upon to allow himself to eat, contrary to his own conscience, and whereby he would be self-condemned; but as the strong believer is addressed in the beginning of the verse, I choose to think he is intended in this part of it; and the rather, because the weak believer is taken notice of in the next verse, with a peculiar view to this very thing.

Hast thou faith--on such matters?
have it to thyself--within thine own breast
before God--a most important clause. It is not mere sincerity, or a private opinion, of which the apostle speaks; it is conviction as to what is the truth and will of God. If thou hast formed this conviction in the sight of God, keep thyself in this frame before Him. Of course, this is not to be over-pressed, as if it were wrong to discuss such points at all with our weaker brethren. All that is here condemned is such a zeal for small points as endangers Christian love.
Happy is he that condemneth not himself in that which he alloweth--allows himself to do nothing, about the lawfulness of which he has scruples; does only what he neither knows nor fears to be sinful.

Hast thou faith - That all things are pure? Have it to thyself before God - In circumstances like these, keep it to thyself, and do not offend others by it. Happy is he that condemneth not himself - By an improper use of even innocent things! and happy he who is free from a doubting conscience! He that has this may allow the thing, yet condemn himself for it.
