Peacefulpete:
P.S. have you formulated an opinion regarding source critical analyses that see the work as a compilation of Jewish and Christian elements?
Do I have a personal opinion? Not a personal one, no.
As to whether there was such a thing as "Jewish and Christian elements," that would depend on your exact definition on those terms.
In the United States, due to the influence of Protestantism, people tend to see religion in the terms of "denomination," but in the rest of the world, especially in the East where Judaism started, religion is more like something built into society that one acts out and less of something you believe in or sign up for via a creed.
It was not until the late 1800s that Reform Judaism claimed that its branch was a "denomination," a claim that today it no longer really stands by. Judaism is actually a culture or civilization that developed a religion during its history, a religion that has had worldwide influence and has lasted for a very, very long time.
But Judaism is not that religion that it created, anymore than Judaism is Jewish food, Jewish music, Jewish language, Jewish mythology, etc.
Christianity is actually an offshoot of Judaism. Its foundational elements are Jewish. ("Messiah" is a Jewish concept, on which Christianity is based, for example.)
The Book of Revelation is an apocalypse, which is a Jewish genre.
The text employs Jewish tropes and Hebrewisms, inspired by other books in the same genre such as 1 Enoch, 4 Ezra, 2 Baruch, the Apocalypse of Abraham, and--lest anyone forget--the Book of Daniel.
And Christianity, at the time of its writing, may have seen itself as nothing more than another sect of Judaism. As the Acts of the Apostles tells us, 'many thousands of believers among the Jews were all zealous followers of the Law.' (See Acts 21:17-26.) Since Victorinus and the Church Fathers favored the preterist view that Revelation dealt with the time suffered by the disciples during the author's writing, there is a possibility that the "Great Harlot" represents Jerusalem, which the Jewish Christians felt had proved itself unfaithful to God, and the call to "get out of her" and the description of her destruction involves the Roman attack on Jerusalem when the Temple fell in 70 CE. Rome did not fall during the time of the writing of the Book of Revelation.--Revelation 18:4, 9-10; compare Jesus' words at Matthew 24:15-21.
So is this a "Christian" work? Or is this a "Jewish" work? Did Christianity create works that were free of Judaism, and did these become part of the New Testament?
I guess it depends on how you, personally, look at things.
