Well you know what they say: "If it's new, it ain't true!"
The New Testament replaces the Old Testament.
Hmm . . . something "new" replacing something that had previously always been universally accepted, but now suddenly we all "know better" and have to "update" our entire worldview.
I don't know . . . that doesn't sound very "conservative" to me. In fact, it sounds downright . . . progressive.
Look at how uncomfortable in their own skin many of the paleos, indentations, nationalists are having to share the Bible and the roots of their own tradition with “the Jew”. Really is a form of ancestor worship.
The very thought that moral authority perhaps does not stem from their own “blood and soil” must be anathema to them.
At least the neo-pagan ones who reject all Abrahamic religions as alien and having been imposed by “the outsider” (we know who) are more self-consistent.
