Let your work not be for the food which comes to an end, but for the food which goes on for eternal life, which the Son of man will give to you, for on him has God the Father put his mark.
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.
For this reason, if food is a cause of trouble to my brother, I will give up taking meat for ever, so that I may not be a cause of trouble to my brother.
