Venus, I agree with some of your reasoning but not the premises on which they stand.
Jesus was never misquoted; all sayings attributed to him were written by later writers. No one ever took down and wrote verbatim and no one had the ability to memorise his words fifty years or more later and then write them down.
It was more like writing a contrived documentary about a hero who never lived but fabricating the the stories (borrowed from earlier god-man heroes such as Mithra, Dionysus, Orpheus etc.) to create an enticing religious narrative for the temple cults in the first and second centuries.
It is tiresome and unpopular to say it but here is a case where the world really has been well and truly duped in the fictional person of Jesus. The reason for his durability is to be found in Roman politics.
The god-man saviour was a mythical archetype known to all the ancients. By Imperial decree under Constantine the "Catholic" Jesus myth was sold to Greeks, Jews and all comers, the new fusion religion shored up support for the Roman empire by making a catholic i.e. an all embracing or universal church culled from the disparate cults in the third and early fourth centuries. This was part of the standard method of Roman power practice to conquer and control peoples by absorption of their cultures plus the prized gift of high status privilege of Roman citizenship.
Jesus was a cut and paste version of a traditional superman.
