First reading
Brothers and sisters, knowledge puffs up, but love builds up. Anyone who claims to know something does not yet have the necessary knowledge; but anyone who loves God is known by him.
Hence, as to the eating of food offered to idols, we know that “no idol in the world really exists,” and that “there is no God but one.” Indeed, even though there may be so-called gods in heaven or on earth — as in fact there are many gods and many lords — yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist. It is not everyone, however, who has this knowledge.
Since some have become so accustomed to idols until now, they still think of the food they eat as food offered to an idol; and their conscience, being weak, is defiled. So by your knowledge those weak believers for whom Christ died are destroyed. But when you thus sin against brothers or sisters, and wound their conscience when it is weak, you sin against Christ. Therefore, if food is a cause of their falling, I will never eat meat, so that I may not cause one of them to fall.
