Halal meat in the public marketplace should be an issue to Christians because it is “meat offered to idols” that the Apostle Paul said they must decline to eat for the sake of being a witness to others lest they imply endorsing a pagan religion.
Acts 15:28-29
(28) For it seemed good to the Holy Spirit and to us to lay on you no greater burden than these necessary things:
(29) that you abstain from meats offered to idols, and from blood, and from things strangled, and from fornication; from which, if you keep yourselves, you shall do well. Be prospered.
How many evangelicals are interested in this?
Well, Paul wasn’t the author here in Acts, Luke probably was. Paul was for the passage about meats offered to idols in 1 Corinthians 8:10.
