{13} I know, and am persuaded by the {n} Lord Jesus, that there is nothing unclean of {o} itself: but to him that esteemeth any thing to be unclean, to him it is unclean.

(13) The preventing of an objection: it is true that the right of the law to be schoolmaster is taken away by the benefit of Christ, to those who know it, but yet nonetheless we have to consider in the use of this liberty what is expedient, that we may have regard to our weak brother, seeing that our liberty is not lost in doing this.

(n) By the Spirit of the Lord Jesus, or by the Lord Jesus, who broke down the wall at his coming.

(o) By nature.

People's New Testament

14:14 I know, and am persuaded by the Lord Jesus. The conviction is that of a mind in communion with Christ, enlightened by his Spirit.

That nothing. No kind of food.

Is unclean of itself. Is by its own nature such that it is a sin to partake of it. The legal distinction between clean and unclean animals is abolished.

But to him. If one, uninstructed, considers anything unclean, to his conscience it is so. It is wrong for him to eat it.

Wesley's Notes

14:14 I am assured by the Lord Jesus - Perhaps by a particular revelation. That there is nothing - Neither flesh nor herbs. Unclean of itself - Unlawful under the gospel.

King James Translators' Notes

unclean: Gr. common

Jamieson-Fausset-Brown Bible Commentary

14, 15. I know, and am persuaded by-or rather, "in"

the Lord Jesus-as "having the mind of Christ" (1Co 2:16).

that there is nothing unclean of itself-Hence it is that he calls those "the strong" who believed in the abolition of all ritual distinctions under the Gospel. (See Ac 10:15).

but-"save that"

to him that esteemeth anything to be unclean, to him it is unclean-"and therefore, though you can eat of it with out sin, he cannot."

Matthew Henry's Concise Commentary

14:14-18 Christ deals gently with those who have true grace, though they are weak in it. Consider the design of Christ's death: also that drawing a soul to sin, threatens the destruction of that soul. Did Christ deny himself for our brethren, so as to die for them, and shall not we deny ourselves for them, so as to keep from any indulgence? We cannot hinder ungoverned tongues from speaking evil; but we must not give them any occasion. We must deny ourselves in many cases what we may lawfully do, when our doing it may hurt our good name. Our good often comes to be evil spoken of, because we use lawful things in an uncharitable and selfish manner. As we value the reputation of the good we profess and practise, let us seek that it may not be evil-spoken of. Righteousness, peace, and joy, are words that mean a great deal. As to God, our great concern is to appear before him justified by Christ's death, sanctified by the Spirit of his grace; for the righteous Lord loveth righteousness. As to our brethren, it is to live in peace, and love, and charity with them; following peace with all men. As to ourselves, it is joy in the Holy Ghost; that spiritual joy wrought by the blessed Spirit in the hearts of believers, which respects God as their reconciled Father, and heaven as their expected home. Regard to Christ in doing our duties, alone can make them acceptable. Those are most pleasing to God that are best pleased with him; and they abound most in peace and joy in the Holy Ghost. They are approved by wise and good men; and the opinion of others is not to be regarded.
