Romans 14:3 - Matthew Poole's English Annotations on the Holy Bible

Let not him that eateth despise him that eateth not; i.e. Let not him that makes use of his liberty in eating any thing indifferently, vilify or contemn him that is of a contrary mind, as one that is ignorant and over scrupulous; and let not him that forbears such meats as were of old forbidden, judge and condemn him that is contrary-minded, as profane and over-venturous; notwithstanding such little difference in opinion, let one Christian love and communicate with another. For God hath received him: it is disputed, whether this be meant of the weak or strong Christian; the word judge, which immediately goes before and follows after, carries it rather for the latter. But some think it is meant of both. He that eateth, and he that eateth not, is received by God into his church and family, and indiffercnlly accepted with him, uponanother and a higher account.
