Define united. Most of the gnostic "churches" were small groups of scribes who worked together to produce the scriptures that they then taught from. They were spread across the ancient near east, existed for a few hundred years at best and then were eliminated or absorbed by the Catholic church.
Only a small sect of Mandeans still exist to this day in Iraq.
Oh, and the Dura Europos synagog is in Syria, and is dated to about 244 CE. It would seem to be built by diasporatic Jews due to the art and the scrolls found inside, and also a Torah shrine pointed towards Jerusalem.
Gnostic's were a people not just scribes!
Diasporatic Jews indeed, but what Jew would allow pagan images on their walls! Your out of school now Deepskyy , there is no professor you need to impress by regurgitating what you have been told! Your no longer obligated to follow university teachings, .... your now free to actually read and research History as it was written, not as it was told!
You will find the documents your professors quoted, to be different when your not being graded on the professors bias!
Your the professor now. It's time for you to unlearn what you paid good money to be told what to believe! Some things never change, You get what you pay for! :think:
