Romans 14:3

"Let not him that eateth, despise him that eateth not." He does not say, let him alone, nor does he say, do not blame him, nor yet, do not set him right; but do not reproach him, do not "despise" him, to show they were doing a thing perfectly ridiculous. But of this he speaks in other words. "Let not him which eateth not, judge him that eateth." For as the more advanced made light of these, as of little faith, and falsely healed, and spurious, and still Judaizers, so they too judged these as law-breakers, or as given to gluttony. And of these it is likely that many were of the Gentiles too. Wherefore he proceeds, for God hath received him. But in the other's case he does not say this. And yet to be despised was the eater's share, as a glutton, but to be judged, his that did not eat, as of little faith. But he has made them change places, to show that he not only does not deserve to be despised, but that he can even despise. But do I condemn him? he means. By no means. For this is why he proceeds, "for God hath received him." Why then speakest thou to him of the law, as to a transgressor? "For God hath received him:" that is, has shown His unspeakable grace about him, and hath freed him from all charges against him; then again he turns to the strong.

We are not, then, to abstain wholly from various kinds of food, but only are not to be taken up about them. We are to partake of what is set before us, as becomes a Christian, out of respect to him who has invited us, by a harmless and moderate participation in the social meeting; regarding the sumptuousness of what is put on the table as a matter of indifference, despising the dainties, as after a little destined to perish. "Let him who eateth, not despise him who eateth not; and let him who eateth not, not judge him who eateth."

Those who ate everything, being perfect, looked down on those who did not eat, as people of little faith still attached to Judaism. On the other hand, those who did not eat condemned those who ate everything as lacking self-control. Since among them many were …

Then when he says, let him who eats, he explains how to avoid differences of opinion. First, in regard to the perfect he says: let him who eats, namely, with a secure conscience or even without danger of sensual desire, despise not him who eats …

(1.) Because God hath received them; and we reflect upon him if we reject those whom he hath received. God never cast off any one that had true grace, though he was but weak in it; never broke the bruised reed. Strong believers and weak believers, those that eat and those that eat not, if they be true believers, are accepted of God.

Let not him that eateth, despise him that eateth not,....

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.

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.

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.
