If you closely look at Revelation, it may click in your head (like it just did in mine) that "Mystery Babylon the Great, the Great Harlot" sounds an awful lot like the Sadducees and Pharisees who killed Jesus and persecuted the Apostles, and tried to suck up to Rome.
Paul spoke about a *Jerusalem Below* and a *Jerusalem Above,* in Galatians. Jerusalem Below are the freshly and evil Jews and Jerusalem Above is the Church made up of Christian Jews and Gentiles, the Seed of Abraham in Christ.
Revelation also picks up on this theme by declaring there is a *New Jerusalem,* while also declaring that the Jerusalem Below, which killed Jesus, is called *Sodom* and *Egypt* in a symbolic way. (**Revelation 11:8**)
Also, Revelation repeatedly describes *Babylon* as being an unfaithful adulteress and Harlot. Usually in the New Testament, these phrases are figuratively used to refer to God's people who have become worldly and unfaithful. This would fit in with the Jerusalem Below Paul spoke of in Galatians.
Finally, what Revelation says about *Babylon* being responsible for all the blood of the prophets and apostles matches what Jesus told the Pharisees in **Matthew 23:31-38.**
