c. 386–398 · John Chrysostom, Homilies on the Epistle to the Romans 26
Do not then compel him, but even thyself refrain for his sake, not refraining from it as unclean, but because he is offended, and he will love thee the more. So Paul also advises when he says, “It is good not to eat flesh,” not because it was unclean, but because the brother is offended and is weak.
