Albert Barnes Commentary Romans 14:16

"Let not then your good be evil spoken of:" — Romans 14:16 (ASV)

Let not then your good, etc. That which you esteem to be right, and which may be right in itself. You are not bound by the ceremonial law. You are free from the yoke of bondage. This freedom you esteem to be a good—a favor—a high privilege. And so it is; but you should not make such use of it as to cause injury to others.

Be evil spoken of. Greek, Be blasphemed. Do not use your Christian liberty in such a way as to give cause for railing and unkind remarks from your brethren, so as to produce contention and strife, and thus to give rise to evil reports among the wicked about the tendency of the Christian religion, as if it were adapted only to promote controversy. How much strife would have been avoided if all Christians had regarded this plain rule.

In relation to dress, and rites, and ceremonies in the church, we may be conscious that we are right; but an obstinate adherence to them may only give rise to contention and angry discussion, and to evil reports among people, about the tendency of religion. In such a case, we should yield our private, unimportant, personal indulgence for the good of the cause of religion and of peace.
