Cyrus the Great, who helped the Jews and had influence on them, was Zoroastrian, and that religion was still practiced through the time of Christianity. What, you thought Christianity developed from a vacuum? That's ignorant. I know your brainwashing will allow you to accept nothing but The TruthTM, but history does exist aside from your religion.
Satan IS the central figure.
You're the one worrying about Satan. Everyone else is laughing at you.
For some gruesome examples of just how far some go in this CULT, remember what happened in mexico a few years back during spring break.
For some gruesome examples of just how far some go in this Jesus CULT, remember, well, millions of deaths throughout the centuries, up to and including modern times. Pot, meet kettle.
Christianity is the following of Christ's example. It stems from Judaism. Satan comes from ealy biblical times, beginning with genisis.
The sun worshipers (Zoroastrians) had nothing to do with it at the time, as they didn't exist.(they stem from Persians in the Iran region) Perhaps you should read better material, rather than stuff on web sites which likes to confuse the faiths and run them into each other. Your ignoring about 5,000 years of history.
Can you document millions? Can you document Christianity as the cause?
I don't think so.
I, on the other hand, can document 25 million deaths in the cause of atheism in the 20th century alone.
Shalom.
