And if because of food your brother is troubled, then you are no longer going on in the way of love. Do not let your food be destruction to him for whom Christ went into death.

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.

I am free to do all things; but not all things are wise. I am free to do all things; but I will not let myself come under the power of any.

But God's approval of us is not based on the food we take: if we do not take it we are no worse for it; and if we take it we are no better.

So then, if it is a question of food or drink, or any other thing, whatever you do, do all to the glory of God.

The work

For by his act we were given existence in Christ Jesus to do those good works which God before made ready for us so that we might do them.

For I am certain of this very thing, that he by whom the good work was started in you will make it complete till the day of Jesus Christ:

All

I am conscious of this, and am certain in the Lord Jesus, that nothing is unclean in itself; but for the man in whose opinion it is unclean, for him it is unclean.

Not that which goes into the mouth makes a man unclean, but that which comes out of the mouth.

And the voice came to him a second time, What God has made clean, do not you make common.

Who keep men from being married and from taking food which God made to be taken with praise by those who have faith and true knowledge.

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.

General references

And flesh touched by any unclean thing may not be taken for food: it is to be burned with fire; and as for the flesh of the peace-offerings, everyone who is clean may take it as food:

The priests may not take for food any bird or beast which has come to a natural death or whose death has been caused by another animal.

Not looking everyone to his private good, but keeping in mind the things of others.
