But what explains WHY they worshiped "a man who was crucified"?
And, again, if we go by Lucian, then all we have . . .
But we don't "go by" Lucian for events which happened more than 100 years earlier. If you want to know what happened in 30 AD, you rely on the sources nearer to that time.
. . . all we have as late as 165 CE is a group of splinter Jews who worshipped a man named Jesus who was crucified (not resurrected).
No, Lucian doesn't say he was "not resurrected."
But you're missing his point, that "a man who was crucified" was worshiped. This was a put-down of those Jews, who were out of line to worship such an object.
Virtually all worshipers believed in an
ancient deity/hero going back 1000 years or more, such as Zeus or Apollo or Athena or Asclepius or Hercules, etc. Or there was worship of the emperor-god, a famous and powerful political figure. We can easily explain this kind of worship as normal. But to worship "a man who was crucified" violated all the norms, and such a worshiper was ridiculed.
So the question has to be asked: WHY? There has to be an explanation
why they worshiped someone like this, of such low status and reproach. To not answer this indicates that the likely explanation is something someone doesn't want to hear. It's obvious that many don't want to hear that he resurrected, and that he performed the miracle acts. They are angered at this explanation and recoil with outbursts of contempt when this explanation is offered.
Playing down the miracle acts of Jesus has been the norm, not only today, but going all the way back to the beginning. The snobbery of contempt toward believers was a fact in the 1st century as much as it is today.
There has to be a REASON WHY someone was worshiped.
In Lucian's world there was no religion worshiping "a man" (other than the emperor) as being God or connected to God -- i.e., worshiping a man who was a person in recent history, connected to an historical time and place. If there were any such man-god cults at all, virtually no one took them seriously, so they were totally rejected and ignored in the historical record, receiving no attention from the educated who could have left a written record.
While farther east there was "a man" named Gautama who had worshipers, or "a man" named Krishna, or "a man" named Zoroaster, etc. Assuming they were historical, they had long careers of teaching and impressing their followers, concluding their lives in glory, not shame. And then centuries of mythologizing added to their legends. This explains how they came to be worshiped. No such explanation applies to Jesus, who became worshiped early, after a short career of only 1-3 years, and in a time (100 BC - 100 AD) when there was less belief in miracle stories than virtually any other time in history.
So that Lucian said they worshiped "a man who was crucified," is still further indication that Jesus must have done the miracle acts, because only this explains WHY they worshiped someone so unlikely to be worshiped. So, if "a man who was crucified" is the best you can offer to debunk the Jesus miracles, you're just adding more to the accumulation of evidence that these reported events really did happen. That you can't do any better is just one more indication that the Jesus miracle acts probably did happen. If there was any evidence showing otherwise, you'd have come up with something.
How is it that those trying to debunk something keep ending up doing the opposite, giving still more evidence in favor of what they're trying to debunk?
