Again, I quote the Bible as an atheist, ceding to it no divine authority whatsoever. I treat the Bible as a work of ancient literature and history. I don't assume God spoke through the authors.

If that's how you treat the Bible too, fine. Otherwise, your use of the Bible is likely religious, whereas mine isn't. And that's especially so if you think the Bible is the only scripture inspired by God.

Again, does God speak through the Quran too? If so, why is the Bible the only scripture you quote from? That preference is supposed to have nothing to do with religion and with Christianity's popularity in the US where you live?

If you can't see the difference between the two uses, that's on you, and you're resorting to trolling, because the difference is crystal clear.
