Give a welcome to anyone whose faith is not strong, but do not get into arguments about doubtful points. One person may have faith enough to eat any kind of food; another, less strong, will eat only vegetables. Those who feel free to eat freely are not to condemn those who are unwilling to eat freely; nor must the person who does not eat freely pass judgement on the one who does — because God has welcomed him. And who are you, to sit in judgement over somebody else’s servant? Whether he deserves to be upheld or to fall is for his own master to decide.

[Τὸν δὲ ἀσθενοῦντα τῇ πίστει προσλαμβάνεσθε, μὴ εἰς διακρίσεις διαλογισμῶν. ὃς μὲν πιστεύει φαγεῖν πάντα, ὁ δὲ ἀσθενῶν λάχανα ἐσθίει. ὁ ἐσθίων τὸν μὴ ἐσθίοντα μὴ ἐξουθενείτω, ὁ δὲ μὴ ἐσθίων τὸν ἐσθίοντα μὴ κρινέτω, ὁ θεὸς γὰρ αὐτὸν προσελάβετο. σὺ τίς εἶ ὁ κρίνων ἀλλότριον οἰκέτην; τῷ ἰδίῳ κυρίῳ στήκει ἢ πίπτει.]

(Source (Greek)). Alternate translations:

Him that is weak in the faith receive ye, but not to doubtful disputations. For one believeth that he may eat all things: another, who is weak, eateth herbs. Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him. Who art thou that judgest another man’s servant? to his own master he standeth or falleth.
[KJV (1611)]

If a person's faith is not strong enough, welcome him all the same without starting an argument. People range from those who believe they may eat any sort of meat to those whose faith is so weak they dare not eat anything except vegetables. Meat-eaters must not despise the scrupulous. On the other hand, the scrupulous must not condemn those who feel free to eat anything they choose, since God has welcomed them. It is not for you to condemn someone else's servant: whether he stands or falls it is his own master's business.
[JB (1966)]

Welcome those who are weak in faith, but do not argue with them about their personal opinions. Some people's faith allows them to eat anything, but the person who is weak in the faith eats only vegetables. The person who will eat anything is not to despise the one who doesn't; while the one who eats only vegetables is not to pass judgment on the one who will eat anything; for God has accepted that person. Who are you to judge the servants of someone else? It is their own Master who will decide whether they succeed or fail.
[GNT (1992 ed.)]

Welcome the person who is weak in faith -- but not in order to argue about differences of opinion. One person believes in eating everything, while the weak person eats only vegetables. Those who eat must not look down on the ones who don’t, and the ones who don’t eat must not judge the ones who do, because God has accepted them. Who are you to judge someone else’s servants? They stand or fall before their own Lord.
[CEB (2011)]

Welcome those who are weak in faith but not for the purpose of quarreling over opinions. Some believe in eating anything, while the weak eat only vegetables. Those who eat must not despise those who abstain, and those who abstain must not pass judgment on those who eat, for God has welcomed them. Who are you to pass judgment on slaves of another? It is before their own lord that they stand or fall.
