The following from a frequent commenter here, "Religion of Pieces", was intended as a comment on my post Christians ask if force is needed to protect their religious values, but I decided to use it as a jumping off point for a new post.
Muslims have in the last five years done more for Judeo-Christian unity than all the Popes, Archbishops, Rabbis, Pastors and theologians in the last 500 years.
Faced with the Muslim menace, the various branches of Judeo-Christianity are realising that the values that unite them are vastly more important and more worth striving for than the insignificant details that divide them.
While I agree with the thrust of the comment, I take exception to the term "Judeo-Christian". There has been no such thing since the end of the Judaising heresy in the Apostolic Era. The Catholic Church is the New Israel according to Scripture and the Church subsumed all that was good in Biblical Judaism. Thus to refer to Judeo-Christianity is to refer to a non-existent construct, in much the same way as referring to the "Protestant Church" or the "Christian Church" (meaning the entire body of Christians) is to refer to something which does not exist.
However, it is true that our civilsation and culture are based not only on the Religion founded by Christ and taught by the One, Holy, Roman, Catholic and Apostolic Church. They are also based on Greek thought and Roman law. Thus, you will never see the term Judeo-Christian used by me. What you will see are repeated references to the glories of and the need to defend our Græco-Roman Catholic Civilsation and Culture.
This in no way negates the point made by my commenter. While it is true that the Agarene (vide Genesis xvi) menace is an uniting factor in Western society, I simply make the point that, willy-nilly, like it or not, the people uniting are partakers in that Græco-Roman Catholic Civilsation and Culture by the very fact that they live in lands formed under its ægis.
