“You could be eating beef, chicken, etc., offered up to Allah and not even know it.”
Key words, “not even know it”. Regarding things like this, if you don’t know it, you didn’t do it. Eating food that you KNOW was sacrificed to idols is not the same thing as eating food that was “sacrificed to idols” but there was no clue that it had been. The former is all we can control, and all we, as Christians, are responsible for.
One needs to also consider what “sacrificed to idols” really means.
