Let not him who eats, etc. He wisely and suitably meets the faults of both parties. They who were strong had this fault, -- that they despised those as superstitious who were scrupulous about insignificant things, and also derided them: these, on the other hand, were hardly able to refrain from rash judgments, so as not to condemn what they did not follow; for whatever they perceived to be contrary to their own sentiments, they thought was evil. Hence he exhorts the former to refrain from contempt, and the latter from excessive moroseness. And the reason which he adds, as it belongs to both parties, ought to be applied to the two clauses, -- "When you see," he says, "a man illuminated with the knowledge of God, you have evidence enough that he is received by the Lord; if you either despise or condemn him, you reject him whom God has embraced."

1 - The last clause is by Haldane confined to the strong, and he objects to this extension of it; and certainly the following verse is in favor of his view, for the weak, the condemner, is the person reproved, and therefore the strong is he who to his own master stands or falls. The condemner throughout is the weak, and the despised is the strong. -- Ed

Let not him that eateth - That is, he who has no scruples about eating "meat," etc., who is not restrained by the Law of the Jews respecting the Clean and unclean, or by the fact that meat "may" have been offered to idols.
Despise him - Hold him in contempt, as being unnecessarily scrupulous, etc. The word "despise" here is happily chosen. The Gentile would be very likely to "despise" the Jew as being restrained by foolish scruples and mere distinctions in matters of no importance.
Him that eateth not - Him that is restrained by scruples of conscience, and that will eat only "vegetables;" Romans 14:2. The reference here is doubtless to the "Jew.
Judge him - To "judge" here has the force of "condemn." This word also is very happily chosen. The Jew would not be so likely to "despise" the Gentile for what he did as to "judge" or condemn him. He would deem it too serious a matter for contempt. He would regard it as a violation of the Law of God, and would be likely to assume the right of judging his brother, and pronouncing him guilty. The apostle here has happily met the whole case in all disputes about rites, and dress, and scruples in religious matters that are not essential. One party commonly "despises" the other as being needlessly and foolishly scrupulous; and the other makes it a matter of "conscience," too serious for ridicule and contempt; and a matter, to neglect which, is, in their view, deserving of condemnation. The true direction to be given in such a case is, "to the one party," not to treat the scruples of the other with derision and contempt, but with tenderness and indulgence. Let him have his way in it. If he can be "reasoned" out of it, it is well; but to attempt to "laugh" him out of it is unkind, and will tend only to confirm him in his views. And "to the other party," it should be said they have no "right" to judge or condemn another. If I cannot see that the Bible requires a particular cut to my coat, or makes it my duty to observe a particular festival, he has no right to judge me harshly, or to suppose that I am to be rejected and condemned for it. He has a right to "his" opinion; and while I do not "despise" him, he has no right to "judge" me. This is the foundation of true charity; and if this simple rule had been followed, how much strife, and even bloodshed, would it have spared in the church. Most of the contentions among Christians have been on subjects of this nature. Agreeing substantially in the "doctrines" of the Bible, they have been split up into sects on subjects just about as important as those which the apostle discusses in this chapter.
For God hath received him - This is the same word that is translated "receive" in Romans 14:1. It means here that God hath received him kindly; or has acknowledged him as his own friend; or he is a true Christian. These scruples, on the one side or the other, are not inconsistent with true piety; and as "God" has acknowledged him as "his," notwithstanding his opinions on these subjects, so "we" also ought to recognise him as a Christian brother. Other denominations, though they may differ from us on some subjects, may give evidence that they are recognised by God as his, and where there is this evidence, we should neither despise nor judge them.

Let not him that eateth - The Gentile, who eats flesh, despise him, the Jew, who eateth not flesh, but herbs. And let not him, the Jew, that eateth not indiscriminately, judge - condemn him, the Gentile, that eateth indiscriminately flesh or vegetables.
For God hath received him - Both being sincere and upright, and acting in the fear of God, are received as heirs of eternal life, without any difference on account of these religious scruples or prejudices.

(3) Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for (4) God hath received him.
(3) In such a matter, says the apostle, let neither those who know their liberty proudly despise their weak brother, neither let the unlearned wickedly or perversely condemn that which they do not understand. (4) The first reason: because both he that eats and he that does not eat is nonetheless the member of Christ, neither he who does not eat can justly be condemned, neither he who eats be justly condemned: now the first proposition is declared in the sixth verse which follows (Romans 14:6).

Let not him that eateth, despise him that eateth not,.... Such who had a greater degree of Gospel light and knowledge, and made use of their Christian liberty in eating any sort of food, were not to despise as they were apt to do, such as abstained therefrom on account of the ceremonial law, as weak, ignorant; superstitious, and bigoted persons; or were not to set them at naught, or make nothing of them, as the word signifies, have no regard to their peace and comfort; but, on the other hand, were to consider them as brethren in Christ, though weak; and as having a work of God upon their souls, and therefore to be careful how they grieved them, destroyed their peace, or laid stumblingblocks in their way:
and let not him which eateth not, judge him that eateth: such who thought it not their duty to eat anything, but to forbear the use of some things directed to in the law, were not to censure and condemn, as they were apt to do, those who used their liberty in these things, as profane persons, and transgressors of the law of God; but leave them to the last and righteous judgment, when every one must be accountable to God for the various actions of life: the reason used to enforce this advice on both parties is,
for God hath received him: which respects both him that eateth, and him that eateth not, him that is despised, and him that is judged; and is a reason why one should not despise, nor the other judge, because God had received both the one and the other into his heart's love and affection, into the covenant of grace, and into his family by adoption: they were received by Christ, coming to him as perishing sinners, according to the will of God; whose will it likewise was, that they should be received into church fellowship, as being no more strangers and foreigners, but fellow citizens with the saints, and of the household of God; and God had also received them into his service, and they were made willing to serve him, as well as to be saved by him; and did serve him acceptably with reverence and godly fear, in righteousness and holiness; and this is the rather to be taken into the sense of this passage, because of what follows.

Let not him that eateth despise--look down superciliously upon "him that eateth not."
and let not him that eateth not judge--sit in judgment censoriously upon "him that eateth."
for God hath received him--as one of His dear children, who in this matter acts not from laxity, but religious principle.

Despise him that eateth not - As over - scrupulous or superstitious. Judge him that eateth - As profane, or taking undue liberties. For God hath received him - Into the number of his children, notwithstanding this.
