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.
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.
