Romans 14:16 - Matthew Poole's English Annotations on the Holy Bible

Here is another argument against offences; it will cause our good to be blasphemed, or evil spoken of. Some, by good here, would understand the Christian faith, or the gospel in general; but others do rather understand it of our Christian liberty in particular: q.d. Give none occasion for this great privilege of your Christian liberty to be traduced; use it so, as that neither the weak Christian nor the infidel may reproach or accuse you as licentious or contentious: see 1 Corinthians 10:29,30.
