Judeo-Christianity, you stupid motherfuckers.
Read. A. God. Damn. Book. My. God.
Once one recognizes that Christianity has historically engendered antisemitism, then this so-called tradition appears as dangerous Christian dogma (at least from a Jewish perspective). For Christians, the concept of a Judeo-Christian tradition comfortably suggests that Judaism progresses into Christianity—that Judaism is somehow completed in Christianity. The concept of a Judeo-Christian tradition flows from the Christian theology of supersession, whereby the Christian covenant (or Testament) with God supersedes the Jewish one. Christianity, according to this myth, reforms and replaces Judaism. The myth therefore implies, first, that Judaism needs reformation and replacement, and second, that modern Judaism remains merely as a “relic”. Most importantly the myth of the Judeo-Christian tradition insidiously obscures the real and significant differences between Judaism and Christianity.
