“Christian” includes all that was Jewish before Christ and was fulfilled by Him. “Judeo” includes all that is Jewish since Christ, and is premised on rejecting Him. Hence the incompatibility. Christians embrace the religion of the Old Testament through their embrace of the religion that fulfills and completes it: the Catholic Faith. We do not embrace the religion of post-Christ ethnic Jews who have distorted that Old Testament in order to deny their Messiah. Thus, there is no need for “Judeo” to modify “Christian.” All is complete, pure, and fulfilled in “Christian.” Hence, after the coming of Christ, “Judeo-Christian” is an oxymoron. It’s like saying “Antichrist-Christ.” It’s incoherent and nonsensical. No one requires equivocal, distorting, propagandistic words and terms to articulate the TRUTH of Christ. He stands alone, complete, fulfilled, and fulfilling. We reject nothing that was Jewish and pointed toward Him. We reject everything that is Jewish that continues to reject Him. Christ is King.
