Was Jesus of Nazareth a religious loon?

[Jehanne]

What relevance do you think this...

The Gospel of Judas is a Gnostic gospel. The content of consists of conversations between Jesus and Judas Iscariot. Given that it includes late 2nd century theology, it is thought to have been composed in the 2nd century by Gnostic Christians, rather than the historic Judas himself. The only copy of it known to exist is a Coptic language text that has been carbon dated to 280 AD, plus or minus 60 years. It has been suggested that the text derives from an earlier manuscript in the Greek language. An English translation was first published in early 2006 by the National Geographic Society.

...has to the question you're answering by linking to it?  I'd love to get this thing back out of the maze where we're being asked to consider the zombie horde as a historical event that must have happened, according to a scholarly consensus™...which Vicki purports to be expressing.

All the historical evidence is that there was no early Christian Church; rather, there was a diverse and conflicting set of belief systems, some of which had some tenuous connection to the historical Jesus of Nazareth, who was completely Jewish, but an apocalyptic prophet of his day, one of many.  Over time, the proto-Orthodox would emerge out of the chaos of the early Christian communities, but without having any connection to the earliest Christian belief systems, the earliest of which were fully Jewish, like Jesus.  Eventually, the institutional Catholic Church would begin to form, whose theology was formulated and laid down by Augustine of Hippo, Ambrose and their other contemporaries, and with the Edict of Toleration under the Roman Emperor Constantine, the Catholic Church would begin to gain prominence in the West, while the Eastern Roman Empire (after the gradual fall of its Western counterpart) would eventually evolve away from the Latin traditions of Rome and into the Greek traditions of Byzantium, all the while maintaining its link to its Roman past and identity.  In the West, Church & State would, gradually, begin to evolve into one system of varying fiefdoms and other quasi-fiefdom systems of rule with Church & State constantly battling for supremacy.  Eventually, the rise of the Italian Renaissance, followed by the scientific revolution and the Enlightenment would begin to whittle away the millennial influence of medieval Catholicism, leading to the mishmash of Christian communities and traditions of our day.

Jesus, if he were alive, would recognize none of this, the religions that bear his name being completely alien to him.
