The following article was not written by me but I wholly agree with the message. The author writes what I have been led to believe, especially when you consider Revelation 14:1-5. There is no distinction between Jewish and non-Jewish believers. There is only the historical fact of those who were part of the nation of Israel and came to trust in Jesus Christ. See my comments on Revelation 14 here.
Within conservative circles, particularly among evangelicals in that court, it is not uncommon to hear the phrase “Judeo-Christian”. This expression often modifies something that pertains to the history or tradition of Christendom. Most people think nothing of it. They are familiar enough with the Bible to know that the Old Testament is about Israel and the Hebrews, and the New Testament is about Christ incarnating to Israel and going to all the nations. But the reality is that Christianity was not formed out of this thing called “Judaism.” Christianity is the true biblical religion, and Judaism is the religion formed after faithful Jews, and believing Gentiles, were united to Jesus Christ.
Objecting to “Judeo-” modifying Christianity may seem pedantic. It may seem like much ado about nothing. What is the big deal if “Judeo-“ modifies “Christian”? After all, it’s just one additional word. But the question of whether Christ was co-eternal with the Father or was created was literally over a single letter (iota). Words matter. Definitions matter. They carry tremendous significance. The problem with the phrase is that it reveals our misunderstanding of what the Old Testament is, and who the people of God were, in the Old Testament. The phrase reveals our misunderstanding of the meaning of the coming of Jesus Christ. Most importantly, it reveals our misunderstanding of the relationship between biblical Israel and modern Jewish identity.
