Römer 14:14

I know, and am persuaded by--or rather, "in" the Lord Jesus--as "having the mind of Christ" (Co1 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 Act 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."

The apostle having, in the former chapter, directed our conduct one towards another in civil things, and prescribed the sacred laws of justice, peaceableness, and order, to be observed by us as members of the commonwealth, comes in this and part of the following chapter in like manner to direct our demeanour one towards another in sacred things, which pertain more immediately to conscience and religion, and which we observe as members of the church. Particularly, he gives rules how to manage our different apprehensions about indifferent things, in the management of which, it seems, there was something amiss among the Roman Christians, to whom he wrote, which he here labours to redress. But the rules are general, and of standing use in the church, for the preservation of that Christian love which he had so earnestly pressed in the foregoing chapter as the fulfilling of the law. It is certain that nothing is more threatening, nor more often fatal, to Christian societies, than the contentions and divisions of their members. By these wounds the life and soul of religion expire. Now in this chapter we are furnished with the sovereign balm of Gilead; the blessed apostle prescribes like a wise physician. "Why then is not the hurt of the daughter of my people recovered," but because his directions are not followed? This chapter, rightly understood, made use of, and lived up to, would set things to rights, and heal us all.

14:14 no food, in and of itself, is wrong to eat (literally nothing is common in itself): The word common signals that the root concern that Paul was addressing was Jewish purity regulations. Jews described food as common if it was not clean (i.e., not kosher), thereby causing a Jew to become ritually impure (see Lev 11; cp. Mark 7:2, 5; Acts 10:14). Paul again follows the teaching of Jesus that “every kind of food is acceptable in God’s eyes” (Mark 7:19). • for that person it is wrong: The truth that no food is wrong to eat was not easy for pious Jews to accept because they had been raised to honor God by avoiding certain foods. Paul urges those who are strong in faith not to force others to violate their consciences (cp. 1 Cor 8:1-13).
