1 Corinthians 8:9-11

9You are free to eat any kind of food. You understand that. But other Christians do not understand so well. So you must be careful. Do not cause them to do something that they think is wrong.

10You may be eating food in a place where people worship idols. Then another Christian sees you there. You know that the idols are not real gods. But the other Christian may have weak thoughts about this. So, because he sees you, he may think that he can eat that food too.

11Because you understand properly, you are hurting someone who does not understand so well. In that way, the life of your Christian friend has become completely spoiled. Remember that Christ died to save that friend.
