I've only recently started reading the source material and I've learned that the Gnostics believe that the God in the Torah is actually an imperfect God (described as resembling a dragon) and not the true Father of everything. Jesus Christ's father is not the Torah God but the true Father of everything. Jesus Christ was trying to save humanity from the Torah God.
Seems pretty accurate to me. Many people say that jews worship the devil. Well, the Gnostics basically said the same thing in texts over 2000 years old. I've also heard the Torah God is a dragon bit before and thought it was a modern view. I didn't realize it literally was written in texts 2200 years old.
How could it have happened without the OT happening? Well, it couldn't have but I'm not saying the OT didn't happen just that the OT God is an imperfect God.
We know what good and evil is because Eve at the fruit and gave it to Adam to eat.
Jesus Christ didn't pluck humanity out of the material world such that evil ceased to exist for us but he showed us the way to leave the material world such that evil wouldn't follow us.
No. Principally jews are decieved. They think they worship God, but they don't. Now, some of them actually don't believe they worship only God, and believe they worship the devil too. These jews are Mysitic jews. They're retarded and decieved even from the standard jews' viewpoint. Then there are devil worshippers who are jewish. Literally satanists, who may or may not believe that satanism/their flavor of it is the true fulfillment of judaism, e.g. Marina Abramovitch.
