Actually point 2 itself has two agreements (Remsburg and Marshall):
2a. Jesus of Nazareth was a flesh and blood man but the Gospels tell us nothing about him ala King Arthur or Robin Hood
2b. Jesus of Nazareth was a flesh and blood man and stripped of their supernatural and known non-historical elements the Gospels tell a reasonable picture of his life.
Point 2a cannot be argued because no evidence will be able to be presented. To make a valid or strong argument one must have data. If the Gospels tell us nothing about Jesus of Nazareth then no argument can be made.
Point 2b constitutes a contradiction. If we strip Jesus of Nazareth of the supernatural and non-historical elements the Gospel tells us Nothing.
Point 2b. cannot be argued because the Gospels would be discredited.
Totally nonsensical per the examples of Robin Hood and King Arthur.
Point 2b would be the absolute minimal Jesus ie in 1st century Galilee
or earlier a man preached a message that resulted in him being crucified by the local officials. Remember this is
Biblical scholar I. Howard Marshall's minimal definition of a historical Jesus ie a flesh and blood man as opposed to Dr. Who or King Lear
but the stories about him have no more validity then those of King Arthur.
THIS IS THE DEFINITION OF A MODERN BIBLICAL SCHOLAR; DEAL WITH IT.
The problem with this argument is again Robin Hood and King Arthur ie native is essentially false part of historical myth.
Jesus could have been a real human being but the story about him is essentially false. In other words the Gospel account has no more historical validity then the stories of George Washington and the Cherry Tree, Davy Crockett and the Frozen Dawn, Jesse James and the Widow, or the many Penny Dreedful-Dime Novels starring people like Buffalo Bill, "Wild Bill" Hickok, and Annie Oakley.
The problem with your argument is that Jesus could have been a figure of mythology.
Romulus, Remus, Achilles, Perseus, Apollo, Jupiter, Adam, Eve, Cain, Abel and hundreds of characters of antiquity are considered figures of mythology.
The problem is you have
three types of mythology: Historical, Philosophical, and Poetical.
Christopher Columbus sailing west to prove the Earth was round is as much a historical myth as the stories of King Arthur and Robin Hood; the only difference is Columbus is on the "slightly colored and the narrative essentially true" part of the historical myth spectrum while King Arthur and Robin Hood are on the "small residuum of truth remains and the narrative is essentially false" side.
No sane person can say George Washington, Davy Crockett, Jesse James , Buffalo Bill, "Wild Bill" Hickok, and Annie Oakley themselves were nonhistorical but also no sane person can argue against these particular stories of them are "possessing no more substantial claims to historical fact than the old Greek or Norse stories of gods and heroes" (very definition of Christ Myth in 1982, 1996 editions of International Standard Bible Encyclopedia: E-J)
No sane person can say Romulus, Remus, Achilles, Perseus, Apollo, Jupiter, Adam, Eve, Cain, and Abel were figures of history.
No more figures of history then the miracle working rose from the dead Jesus of the Gospel.
But that doesn't mean there wasn't flesh and blood people behind the stories as far as the Euhemerism mind set goes.
Remember that Romulus and Remus are considered legend ie
historical myth. Jupiter aka Zeus was at one time considered to be a flesh and blood king who died on Crete (Zeus Is Dead: Euhemerus and Crete, S. Spyridakis, The Classical Journal, Vol. 63, No. 8, May, 1968, pp. 337-340.) and Eusebius in the 4th century CE accepted Heracles as a flesh and blood man who by birth was an Egyptian and was a king in Argos (
Preparation of the Gospel (10.12))
If anything it is this Euhemerism mind set is what Justin Martyr really meant when he wrote "When we say that Jesus Christ was produced without sexual union, was crucified and died, and rose again, and ascended to heaven, we propound nothing new or different from what you believe regarding those whom you call the sons of Jupiter." ie just as you made exaggerations of whom you call the sons of Jupiter
who actually lived so the same had been done to Jesus Christ.
The "small residuum of truth remains and the narrative is essentially false" part of the historical myth spectrum must terrify apologists; otherwise why would they label ideas that go this route "Christ Myth" as seen with Frazer, Robertson, Mead, Wells post
Jesus Myth, and many others? Why? Because it accepts that there was a Jesus but that the Gospels tell nothing about him...other then he existed in the past at sometime.
