I know, with confidence in the Lord Jesus, that nothing is unclean in and of itself. But to him who considers anything to be unclean, it is unclean to him.
And he said to them: "You know how abominable it would be for a Jewish man to be joined with, or to be added to, a foreign people. But God has revealed to me to call no man common or unclean.
For if anyone sees someone with knowledge sitting down to eat in idolatry, will not his own conscience, being infirm, be emboldened to eat what has been sacrificed to idols?
But knowledge is not in everyone. For some persons, even now, with consent to an idol, eat what has been sacrificed to an idol. And their conscience, being infirm, becomes polluted.
All things are clean to those who are clean. But to those who are defiled, and to unbelievers, nothing is clean; for both their mind and their conscience have been polluted.
