My union with the Lord Jesus makes me certain that no food is of itself ritually unclean; but if you believe that some food is unclean, then it becomes unclean for you.
Do not, because of food, destroy what God has done. All foods may be eaten, but it is wrong to eat anything that will cause someone else to fall into sin.
Such people teach that it is wrong to marry and to eat certain foods. But God created those foods to be eaten, after a prayer of thanks, by those who are believers and have come to know the truth.
Everything is pure to those who are themselves pure; but nothing is pure to those who are defiled and unbelieving, for their minds and consciences have been defiled.
Do not let all kinds of strange teachings lead you from the right way. It is good to receive inner strength from God's grace, and not by obeying rules about foods; those who obey these rules have not been helped by them.
They make proud and stupid statements, and use immoral bodily lusts to trap those who are just beginning to escape from among people who live in error.
