Romans 14:1-2

1 Receive one who is weak in the faith, but not to disputes over doubtful things.

² For one believes he may eat all things, but he who is weak eats only vegetables.

in the faith — should be “in faith.” Not referring to Christianity (the faith) but to reliance.

weak — lacking in understanding of Christian liberty with faith in Christ alone — having scruples about unimportant matters — not moral weakness

not to doubtful disputations — unreservedly and not for the purpose of judging or criticizing

receive = embrace
