Romans 14:3

“Let not him that eateth, despise him that eateth not, etc..] 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…”

“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 - 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…”

“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. Romans 14:5”

“14:3-4 look down on . . . condemn: The “strong,” those who prided themselves on their enlightened freedom in Christ, looked with disdain on those they considered to be “weak.” The weak, in turn—certain that they were following the true route to piety—condemned the strong for their laxness. These attitudes, over different issues, are mirrored throughout the history of the Christian church. • God has accepted them: Both the weak and the strong are genuine believers, welcomed by God into his family. Therefore, they have no right to treat each other as if they do not belong (14:4; see also 15:7).”
