Pelagius — on Rom 14:15 (PELAGIUS'S COMMENTARY ON ROMANS)

“Paul did not say that a brother is distressed because of fasting but because of food; therefore you should not incite or constrain anyone by the example of what you eat. If your neighbor eats something which is not good for him against his will, you are no longer loving him as yourself if you are not thinking of his good as much as of your own.”
