This is true, and my tweaking of libertarians is not to be taken as naievte on my part about the likely orientation of the posted article. The simple fact is that "ancient chr*stianity" was an underground apocalyptic movement. "Chr*stendom" or "chr*stian civilization" was an innovation that could only have come into existence after Constantine. This is why traditional Fundamentalist Protestantism (as opposed to today's Pat Robertson variety, which tends to be activist and triumphalist) were "Theocratic anarchists" who felt the world order was inherently wicked and fated to end in the reign of anti-christ. It didn't just happen to be evil at the present time--it was inherently evil and could not be converted. All traditional Fundamentalists could do was "snatch souls from the burning" and wait the second coming. This is a far cry from contemporary Fundamentalism, which has made its peace with the concept of chr*stendom.
All that being said, the fact is that when chr*stendom did form it got many of its ideas about society and economics from the Jewish Torah simply because it had nowhere else to turn to (the "new testament" certainly doesn't contain any instructions for the right ordering of society). Rightwing Catholicism has always borrowed heavily from the laws for apportioning the Land of Israel among the tribes, the laws of Shemittah and Yovel (sabbatical and Jubilee years), and the "just weights and just measures." This makes the anti-Semitism of the Catholic Right all the more heartbreaking, since what winds up being discredited are legitimate economic concepts.
The main thing to remember about chr*stianity is, the more similar to Judaism, the more anti-Jewish; the more radically different from Judaism, the more pro-Jewish (with Rightwing Catholicism and pro-Jewish antinomian Fundamentalism as the archtypes of this rule).
