They cite as proof Romans 14:14 Romans 14:14I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteems any thing to be unclean, to him it is unclean.
American King James Version×, in which Paul wrote, "I know and am convinced by the Lord Jesus that there is nothing unclean of itself; but to him who considers anything to be unclean, to him it is unclean."
This approach, however, fails to consider the context of Paul's letter as well as the specific Greek words he used.
Many Bible resources agree that Paul wrote the book of 1 Corinthians around A.D. 55 and that he wrote his epistle to the Romans from Corinth in 56 or 57. The food controversy in Corinth (reflected in chapters 8 and 10) was over meat sacrificed to idols.
Since Paul was writing to the Romans from Corinth, where this had been a significant issue, the subject was fresh on Paul's mind and is the logical, biblically supported basis for his comments in Romans 14.
Understanding Paul's intent
Those who assume the subject of Romans 14 is a retraction of God's law regarding clean and unclean animals must force this interpretation into the text because it has no biblical foundation. The chapter itself shows that the discussion concerned meat sacrificed to idols.
Romans 14:2 Romans 14:2For one believes that he may eat all things: another, who is weak, eats herbs.
American King James Version×contrasts the person who "eats only vegetables" with the one who believes "he may eat all things"— meat as well as vegetables. Romans 14:6 Romans 14:6He that regards the day, regards it to the Lord; and he that regards not the day, to the Lord he does not regard it. He that eats, eats to the Lord, for he gives God thanks; and he that eats not, to the Lord he eats not, and gives God thanks.
American King James Version×discusses eating vs. not eating and is variously interpreted as referring to fasting (not eating or drinking), vegetarianism (consuming only vegetables) or eating or not eating meat sacrificed to idols.
Romans 14:21 Romans 14:21It is good neither to eat flesh, nor to drink wine, nor any thing whereby your brother stumbles, or is offended, or is made weak.
American King James Version×shows that meat offered to idols was the underlying issue of this chapter: "It is good neither to eat meat nor drink wine nor do anything by which your brother stumbles or is offended or is made weak." The Romans of the day commonly offered both meat and wine to idols, with portions of the offerings later sold in the marketplace.
The Life Application Bible comments on verse 2: "The ancient system of sacrifice was at the center of the religious, social, and domestic life of the Roman world. After a sacrifice was presented to a god in a pagan temple, only part of it was burned. The remainder was often sent to the market to be sold. Thus a Christian might easily—even unknowingly—buy such meat in the marketplace or eat it at the home of a friend.
"Should a Christian question the source of his meat? Some thought there was nothing wrong with eating meat that had been offered to idols because idols were worthless and phony. Others carefully checked the source of their meat or gave up meat altogether, in order to avoid a guilty conscience."
Paul explains in 1 Corinthians 8 that the main concern for a Christian is to not defile his own conscience or the conscience of other Christians. Jewish Christians especially might have been inclined to feel contaminated by anything related to idolatry. But because an idol cannot, by itself, render anything pure or defiled, a person's conscience, not the idol, is the real issue.
So what is the point of Paul's instruction about eating or not eating in Romans 14? Depending on their consciences, early believers had several choices. Those wishing to be sure of avoiding meat sacrificed to idols could choose to eat only vegetables or fast—avoid food altogether—when faced with the prospect of consuming foods of suspicious background.
For those whose consciences were not troubled by eating meat purchased in local markets just because it might have been ceremonially offered to idols, that option was open to them with one important restriction. They were (especially at group meals where offenses were more likely to occur) to consider first the conscience of others who were present, to be careful to give no offense.
Within this context, said Paul, "let each be fully convinced in his own mind" (Romans 14:5 Romans 14:5One man esteems one day above another: another esteems every day alike. Let every man be fully persuaded in his own mind.
American King James Version×) because "whatever is not from faith is sin" (Romans 14:23 Romans 14:23And he that doubts is damned if he eat, because he eats not of faith: for whatever is not of faith is sin.
American King James Version×).
Greek words clarify Paul's meaning
An understanding of the Greek words Paul used can also help us understand Paul's meaning.
The New Testament writers referred to two concepts of unclean, using different Greek words to convey the two meanings. Unclean could refer to animals God did not intend to be consumed as food (listed in Leviticus 11 and Deuteronomy 14). Unclean could also refer to ceremonial uncleanness.
In Romans 14 Paul uses the word koinos, which means "common" (W.E. Vine, Vine's Complete Expository Dictionary of Old and New Testament Words, 1985, "Unclean," p. 649). In addition to the meanings of "common" and "ordinary" (see Acts 2:44 Acts 2:44And all that believed were together, and had all things common;
American King James Version×; Acts 4:32 Acts 4:32And the multitude of them that believed were of one heart and of one soul: neither said any of them that ought of the things which he possessed was his own; but they had all things common.
American King James Version×; Titus 1:4 Titus 1:4To Titus, my own son after the common faith: Grace, mercy, and peace, from God the Father and the Lord Jesus Christ our Savior.
American King James Version×; Hebrews 10:29 Hebrews 10:29Of how much sorer punishment, suppose you, shall he be thought worthy, who has trodden under foot the Son of God, and has counted the blood of the covenant, with which he was sanctified, an unholy thing, and has done despite to the Spirit of grace?
American King James Version×), the word also applied to things considered polluted or defiled. This word, along with its verb form koinoo, is used in Mark 7:2 Mark 7:2And when they saw some of his disciples eat bread with defiled, that is to say, with unwashed, hands, they found fault.
American King James Version×, Mark 7:15-23 Mark 7:15-23  There is nothing from without a man, that entering into him can defile him: but the things which come out of him, those are they that defile the man.  If any man have ears to hear, let him hear.  And when he was entered into the house from the people, his disciples asked him concerning the parable.  And he said to them, Are you so without understanding also? Do you not perceive, that whatever thing from without enters into the man, it cannot defile him;  Because it enters not into his heart, but into the belly, and goes out into the draught, purging all meats?  And he said, That which comes out of the man, that defiles the man.  For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,  Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:  All these evil things come from within, and defile the man.
American King James Version×, where it obviously refers to ceremonial uncleanness.
Koinos and koinoo appear throughout the New Testament to refer to this kind of ceremonial uncleanness. Something could be "common"—ceremonially unclean—even though it was otherwise considered a scripturally clean meat.
An entirely different word, akathartos, is used in the New Testament for those animals Scripture specifies as unclean. Both words, koinos and akathartos, are used in Acts 10, where Peter distinguished between the two concepts of uncleanness by using both words in Acts 10:14 Acts 10:14But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean.
American King James Version×.
When Paul said in Romans 14:14 Romans 14:14I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteems any thing to be unclean, to him it is unclean.
American King James Version×that "I know and am convinced by the Lord Jesus that there is nothing unclean [koinos, or 'common'] of itself," he was making the same point he had made earlier to the Corinthians: Just because meat that was otherwise lawful to eat may have been associated with idol worship does not mean it is no longer fit for human consumption. As seen from the context, Paul wasn't discussing biblical dietary restrictions at all.
Paul goes on to state in Romans 14:20 Romans 14:20For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eats with offense.
American King James Version×that "all food is clean" (NIV). The word translated "clean" is katharos, meaning "free from impure admixture, without blemish, spotless" (Vine, "Clean, Cleanness, Cleanse, Cleansing," p. 103).
"Clean" meats as such aren't addressed in the New Testament, so there isn't a specific word to describe them. Katharos is used to describe all kinds of cleanliness and purity, including clean dishes (Matthew 23:26 Matthew 23:26You blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also.
American King James Version×), people (John 13:10 John 13:10Jesus said to him, He that is washed needs not save to wash his feet, but is clean every whit: and you are clean, but not all.
American King James Version×) and clothing (Revelation 15:6 Revelation 15:6And the seven angels came out of the temple, having the seven plagues, clothed in pure and white linen, and having their breasts girded with golden girdles.
American King James Version×; Revelation 19:8-14 Revelation 19:8-14  And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints.  And he said to me, Write, Blessed are they which are called to the marriage supper of the Lamb. And he said to me, These are the true sayings of God.  And I fell at his feet to worship him. And he said to me, See you do it not: I am your fellow servant, and of your brothers that have the testimony of Jesus: worship God: for the testimony of Jesus is the spirit of prophecy.  And I saw heaven opened, and behold a white horse; and he that sat on him was called Faithful and True, and in righteousness he does judge and make war.  His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.  And he was clothed with a clothing dipped in blood: and his name is called The Word of God.  And the armies which were in heaven followed him on white horses, clothed in fine linen, white and clean.

American King James Version×), gold and glass (Revelation 21:18 Revelation 21:18And the building of the wall of it was of jasper: and the city was pure gold, like to clear glass.
American King James Version×).
Realize also that, in both Romans 14:14 Romans 14:14I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteems any thing to be unclean, to him it is unclean.
American King James Version×and Romans 14:20 Romans 14:20For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eats with offense.
American King James Version×, the word food or meat doesn't appear in the original Greek, but was inserted by later translators. No specific object is mentioned relative to cleanness or uncleanness. The sense of these verses is merely that "nothing [is] unclean [koinos: common or ceremonially defiled] of itself," and "all is clean [katharos: free from impure admixture, without blemish, spotless]."
Paul's point is that association of food with idolatrous activity had no bearing on whether the food was inherently suitable or unsuitable for eating. Understood in its context, Romans 14 does not convey permission to ignore the biblical laws as to which meats are clean or unclean.
