Sorry there is no real Jesus, when referring to historical people away from images formed of many you must use historical names and factual accounts.
Don't be silly. If that's what you believe you might as well throw the entire Torah, mishnah, and gemara in the trash. Jesus, yeshua, jesu, whatever you want to call him, was an actual Jewish person.
Regarding the serpent reference, nothing is clearer then the resemblance and match to the serpent in Genesis:
he promises if you believe in him you will be eternal (Genesis serpent promises Adam and Eve)=Jesus exact promise in believing in him. Reread Genesis remembering Adam means man and Eve is Man's second bride....the false prophet convinces the church and thus mankind to partake of this false promise...we've been death worshipers ever since, believing life is in death and living is for suffering they managed to twist creator and creation in some opposition style thus creating a bizzarro world where people were willing to die for their kings and kingdoms for sake of rewards in the underworld -brilliant!
You are describing the Jesus as conjured by Rome. I agree that this person who claimed to be a coequal third of one unequaled God does not correspond to any real living being ever in existence.
And Yes, it is the Church of Rome who claims to be the earthly representative of this nonexistent being who misleads the gullible by teaching that one can defy the commands of God and not die but instead will become like God and live forever, exactly like the Nachash in the fairy tale.
To say there was no real Jesus is to say there was no real Elijiah who called down fire from the sky and was taken up into heaven in a whirlwind.
Before Christianity was ever assimilated by Rome early Christians who were mostly Jews had the teachings of Jesus hidden and buried in fantastical stories that the enemy could never comprehend or master in the same tradition the secret meaning of the law was hidden in figurative language impossible for the superstitious, deceitful, or irrational to comprehend.
"The kingdom of heaven is like treasure lying buried in a field. The man who found it, buried it again."
"I have not come to bring peace but a sword,"
"Take from my hand this cup of fiery wine and make all the nations to whom I send you drink it. When they have drunk it they will vomit and go mad; such is the sword that I am sending among them."
"From his mouth there went a sharp sword with which to smite the nations."
"Take this cup of wine and drink of it. This is a cup of my blood, the blood of the covenant."
"Just art thou in these thy judgements, thou Holy One who art and wast; for they shed the blood of thy people and of thy prophets and thou hast given them blood to drink."
"Whoever leads into captivity shall go into captivity; he who lifts the sword to kill is bound by the sword to be killed."
