“I’m a Christian. I am free to eat food sacrificed to idols. No big deal.”
True. You are also free to commit sexual immorality, murder, and theft. None of these are salvation issues.
But both Peter and Paul said to avoid these sins and eating meat sacrificed to idols (such as meat sacrificed to allah), as it was harmful to others.
In particular, it may lead a weak brother to believe you accept the tenants of the false religion as valid or acceptable.
Are you a “weaker brother”? Or are you just trying to manipulate me?
