For food destroy not the work of God. All things indeed are pure; but it is evil for that man who eats with offense.
All Commentaries on Romans 14:20 Go To Romans 14
John Chrysostom
AD 407
Here “the work of God” means the salvation of a brother. For these people were so far away from building others up that they were prepared to destroy what God had made, and not for any great matter but for something very trivial. It is not the eating which is unclean but the intention behind it. If you have not put that right but forced him to eat anyway, you have done it to no purpose and have made everything worse. Thinking that something is unclean is not as bad as tasting it when you think it is unclean. In that case you are committing two errors: first, by increasing his opposition by your quarrelsome attitude, and second, by getting him to taste what to him is unclean. As long as you have not persuaded him, do not try to force him.
