Do not let the work of God come to nothing on account of food. All things are certainly clean; but it is evil for that man who by taking food makes it hard for another.
But whoever is a cause of trouble to one of these little ones who have faith in me, it would be better for him to have a great stone fixed to his neck, and to come to his end in the deep sea.
To the clean in heart all things are clean: but to those who are unclean and without faith nothing is clean; they become unclean in mind and in thought.
