I am conscious of this, and am certain in the Lord Jesus, that nothing is unclean in itself; but for the man in whose opinion it is unclean, for him it is unclean.
And he said to them, You yourselves have knowledge that it is against the law for a man who is a Jew to be in the company of one who is of another nation; but God has made it clear to me that no man may be named common or unclean:
Do not let the work of God come to nothing on account of food. All things are certainly clean; but it is evil for that man who by taking food makes it hard for another.
For if a man sees you, who have knowledge, taking food as a guest in the house of an image, will it not give him, if he is feeble, the idea that he may take food offered to images?
Still, all men have not that knowledge: but some, being used till now to the image, are conscious that they are taking food which has been offered to the image; and because they are not strong in the faith, their minds are troubled.
To the clean in heart all things are clean: but to those who are unclean and without faith nothing is clean; they become unclean in mind and in thought.
