"I don't think so, but then again, I'm not a Christian."
What does being a Christian or not have to do with it?
If God is powerless, he's not God so why bother with religion of ANY sort?
As to your other point, I am pulling the pre-Nicaea documents that refer to the Catholic Church, per your request.
My request of you is that you produce the documents whereby you can establish that the Church prior to Nicaea was NOT the Catholic Church, that the bishops who assembled there were not Catholic bishops.
Indeed, I would ask you to define what "Catholic" means, in the perspective you are using it.
What you have said, in effect, is that there was an original Christian religion, the Ebionites, and that the Catholic Church was made up out of whole-cloth in 325 AD.
I have already referred you to one key document: Bishop Eusebius' "History of the Church", much of which was written long before Nicaea. So, there is your first pre-Nicaean document establishing that the Church already existed, well, besides Paul's letter to Timothy.
