The daughter of Babylon is Israel not Rome.
Romans 7:6
“But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.”
As I have said, Paul is the man of lawlessness, who has presumably released you from the Law (Romans 7:6), and who commits lawlessness (Matthew 13:41) & (Romans 7:25) and will be "gathered out", and thrown into the furnace of fire (Matthew 13:42). And there are many harlot "daughters of Babylon" (Revelation 17:5), and Judah and Israel are a minority. The Roman church and her daughters comprise the majority remaining stake holders. You will find the "house of Israel" "scattered among the nations/Gentiles" (Ezekiel 36:17 &19). They need to "come out of her"/escape (Revelation 18:4) & (Zechariah 2:7). Those that will survive the "awesome day of the LORD" (Joel 2:31-32) are those "on Mount Zion, and in Jerusalem". That was not the case in 70 A.D. As for the spirit of the Paul's law, that would most likely be his false prophet demon spirit, as spoken in Revelation 16:13.
