John Calvin Commentary Romans 14:19

"So then let us follow after things which make for peace, and things whereby we may edify one another." — Romans 14:19 (ASV)

Let us then follow, etc. He calls us back, as much as possible, from a mere concern for foods, to consider those greater things that should have the first place in all our actions, and so take precedence. We must indeed eat so that we may live; we ought to live so that we may serve the Lord; and he serves the Lord who by benevolence and kindness edifies his neighbor, for to promote these two things, concord and edification, all the duties of love ought to be exercised. So that this is not considered of little importance, he repeats the sentence he had previously announced—that perishable food is not of such consequence that for its sake the Lord’s building should be destroyed. For wherever there is even a spark of godliness, the work of God is to be seen there; and those demolish this work who, by their unfeeling conduct, disturb the conscience of the weak.

But it must be noted that edification is joined to peace, because some, often, too freely indulge one another, so that they do much harm by their yielding. Therefore, in endeavoring to serve one another, discretion should be exercised, and usefulness considered, so that we may willingly grant to our brother whatever may be useful for furthering his salvation. Paul reminds us of this in another place: All things, he says, are lawful to me; but all things are not expedient; and immediately he adds the reason, Because all things do not edify. (1 Corinthians 10:23).

Nor is it in vain that he repeats again, For meat destroy not, etc., intimating that he required no abstinence that would cause, according to what he had said before, any loss to piety. Though we do not eat anything we please, but abstain from the use of certain foods for the sake of our brothers, yet the kingdom of God remains entire and complete.
