Now I will write about meat that is sacrificed to idols. We know that "we all have knowledge," as you say. But this knowledge puffs a person up with pride, while love helps the church grow stronger.
For us there is only one God, and he is our Father. All things came from him, and we live for him. And there is only one Lord, Jesus Christ. All things were made through him, and we also have life through him.
But not all people know this. Some have had the habit of worshiping idols. So now when they eat meat, they still feel as if it belongs to an idol. They are not sure that it is right to eat this meat. So when they eat it, they feel guilty.
You understand that it's all right to eat anything, so you can eat in an idol's temple. But someone who has doubts might see you eating there, and this might encourage them to eat meat sacrificed to idols too. But they really think it is wrong.
When you sin against your brothers and sisters in Christ in this way and you hurt them by causing them to do things they feel are wrong, you are also sinning against Christ.
So if the food I eat makes another believer fall into sin, I will never eat meat again. I will stop eating meat, so that I will not make my brother or sister sin.
