As one who lives in union with the Lord Jesus, I know and am certain that in its own nature no food is `impure'; but if people regard any food as impure, to them it is.
For, in such cases, the unbelieving husband has become –and is– holy through union with a Christian woman, and the unbelieving wife is holy through union with a Christian brother. Otherwise your children would be unholy, but in reality they have a place among God's people.
