An interesting point that the article raises is the belief in "Judeo-Christian heritage" is largely used in the US. Perhaps it's better to say "Judeo-Protestant" rather than "Judeo-Christian." I don't think that very many Catholics use the term "Judeo-Christian" and, lacking any real connection to the Catholic heritage and history of Europe (regardless of how many Catholics dwell here), the US prefers to cling to and identify with a sort of Judaized Protestantism- hence the obsessive American fixation with Israel over, say, Catholic nations like Spain or Italy and the Holy See.

The Advent took the religious ideation held by the Jews, purified them, and raised them to a cosmic level and anything held sacred by the Jews now became the common property of the Christian Faith. I've never really understood the aforesaid obsession with my fellow Americans in regards to Israel and Jews. I think it's a peculiar trend of American Protestants, which is why I prefer to generically think of myself as simply being a "Christian" in terms of religion- the more I've looked at the Reforms of Luther, so-called, the more they seem like the Follies of Luther. The kind of Christianity that is the common property of the citizens of the US is nothing more than a secularized caricature of the religion of Christ and the Apostles; I think this explains my past ambivalence about Christianity.
