i would bet money its sone zionist invention to exclude muslims since its essentially used as a a distinction between the “civilized” (wtf are judeochristian values and why is it so important to uphold them?) and the others.
Agreed that it’s a Zionist invention but would argue it is not to exclude Muslims but instead to build support for said Zionism by smuggling it into the dispensationalist doctrine of modern Evangelicals in the anglosphere.
Not Christian, but purely from a historical perspective it is pretty clear cut that Jesus was a Jew, Christianity arose from Judaism (as Paul alludes to many times), Judaism has changed a bit too, to be sure, but it is still roughly the same religion. Islam then was adapted from Christianity.
That’s why many use the term Abrahamic religions, rather than Judeo-Christian, as that also includes Islam
