Another biblical symbol that is being used in conjunction with the European Union is the one from Revelation 17 where a “great harlot” is depicted riding a beast. For some strange and unknown reason this symbol is being used to repre­sent the EU!
Strange and unknown?...No, it is Satan's hubris.  He thinks no one is paying attention.  He can't help his Pride--it is his sin.
A bull has long been a symbol of those false gods(can you say golden calf?)
I believe the woman is the Roman "church" and her daughters(protestant) and the beast is the devil's world system.  They ride together.
Shalom
