1 Corinthians 8
Concerning food offered to idols, Paul begins with the principle that knowledge puffs up but love builds up; if anyone supposes they know something, they do not yet know as they ought to know. An idol is nothing in the world, and there is no God but one; though some call themselves gods in heaven or on earth, yet for us there is one God the Father from whom all things come and we exist for him, and one Lord Jesus Christ through whom all things exist and we exist through him. Not everyone possesses this knowledge; some have been so accustomed to idols that they eat food as food offered to an idol, and their conscience, being weak, is defiled. Food will not bring us closer to God; whether we eat or do not eat, we are neither better off if we eat nor worse off if we abstain. But Paul warns: if your liberty becomes a stumbling block to the weak, if your knowledge causes a weak brother or sister to stumble, then you wound their conscience and sin against them; therefore, if food causes my brother to stumble, I will never eat meat, lest I cause a brother to stumble.
