Generally, it is special treatment for religious purposes.
Kosher is distinct from halal, in that Kosher has unecessary (for Christian gentiles) precautions taken in in preparation.
Halal, in contrast, is pagan, and sacrificed to a demon.
While Mathew makes clear that this would not make one “unclean” (in the Jewish sense), Acts and Corinthians makes clear such pagan-sacrificed meat should be avoided.
It’s black-letter, New Testament stuff.
Surprised at the resistance of supposed sola scriptura people here.
“Generally, it is special treatment for religious purposes. “
Yes of course (and not generally but specifically), but my point is (and feel free to read Kosher websites as I do, since I keep Kosher) is that Kosher food is “not blessed nor sacrificed to idols”. Kosher means “fit” and “refers to the manner of supervision, selection, slaughter and preparation” in accordance with Jewish law.
