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.
But all believers do not recognize these facts. Some, from force of habit in relation to the idol, even now eat idol sacrifices as such, and their consciences, being but weak, are polluted.
To the pure everything is pure; but to the polluted and unbelieving nothing is pure, but on the contrary their very minds and consciences are polluted.
