Some people, including American politicians who want to sound “inclusive” and do not want to offend Jews, have taken the Latin term Judaeus and melded it with “Christian” to describe a so-called “Judeo-Christian” tradition or heritage.
While there are many Christians in the world, there are no “Judeos.” The accurate phrase should be “Jewish and Christian” traditions or heritages, without a hyphen.
Each faith community has many religious streams; there is no one single “Jewish tradition” or “Christian tradition,” and there is certainly not a “Judeo-Christian” one.
