evidences shown by you are against you,<quoted text>
Sorry but all the evidence is against you.
The literary evidence alone shows numerous Christian doctrines and sects. The rabid extermination of "Heretical sects" by the Roman Church in the 4th century as well as the (well documented) infighting and attacks on other sects and doctrines prior to 350 AD demonstrate my assertion (which also happens to be the majority scholarly one).
If there was only "One Christian Church" in 350 AD then there would have been no need for Constantine to create one Cristian doctrine and Church and scripture (AKA Bible).
You need to do some research beyond religious propaganda.
you are like man la Mancha fighting with windmills from inkvisitors cells condemned to death
