I've noticed that, among a large cohort of non-Christians and especially atheists on here, many of them take disbelief to what I would consider an extreme. There are many issues so this will likely be a wide-ranging thread.
I. 'Christian martyr stories are made up.' Why? Yes, there are many apocryphal tales but it is absolutely true that Christians were at times persecuted and put to all kinds of terrible deaths by the Roman state. These figures are exaggerated but why should this mean that the whole idea behind Christian martyrs be questioned?
I agree.
II. 'Paul was xyz.' (A Roman spy, a false Christian, didn't really see Jesus etc.) Please prove it. Paul probably had more enemies than friends, but the same might be said of Jesus.
Paul admits in the texts we have that he only ever met Christ in a vision after Christians were already talking about his death. One of the major points regarding Paul is that he was a later convert to Christianity after persecuting those who believed in the resurrection. So, yeah, I'd say that's him not really seeing Jesus, especially when he explicitly states in the texts he wrote that he disagreed with the few people that might have seen a historical Jesus (names James and Peter.)
III. 'Jesus didn't exist.'
The Jesus that Christians believe in, who was God incarnate, conducted miracles, and was resurrected from the dead certainly didn't exist. If you want to insist that there is some grain of truth to the mythical Jesus, feel free, but Jesus as he's popularly understood is a mythical character that didn't exist.
IV. Sources that never seem to be good enough. Yet other histories are not questioned (ex. our best information for Alexander the great comes about 200 years after the fact and almost nothing contemporary survives). Ancient written histories and biographies are full of what modern folks would now consider nonsense and are yet still cited as acceptable histories and especially biographies, yet when one goes to the Gospels all of a sudden it's different, despite the fact that the Gospels are now squarely classed as Greco-Roman biography written in the style of every other such biography (ex. miraculous birth narratives, missing out childhoods, not in chronological order etc.)
This is an incredibly dishonest false equivalency.
Yes, ancient biographies often had mythical elements, but if you think we have the same level of evidence for Jesus as we do Alexander the Great then, quite frankly, you're very confused. Alexander the Great was a major political figure who shaped entire nations, renamed cities, and left his name on everything as he went. There is quite a bit of archaeological and historical evidence for his existence and his activities.
Likewise, even if biographies of deified emperors were filled with mythical elements, we knew those emperors existed because of lineages, coinage, and, yes, contemporary sources.
When it comes to Jesus, we pretty much only have the mythical accounts and the Jamesian reference. All other references are, at the very least, still the subject of academic debate. When all we have to account for the existence of someone is a collection of myths then, yes, that calls into doubt whether they really existed and how much we can actually say about them if they did, since the sources we have are unreliable due to the inclusion of falsified mythical elements.
Whether there was some rabbi who inspired the mythical Jesus or not, the Jesus we're left with is still a mythical figure. Julius Caesar is not. That's the difference and it's an important one.
The minute something is classed as 'religious' it seems far too many people are willing to write it off as a complete waste of space.
Religious claims have an extremely high error rate when investigated. Any new religious claims that arise, therefore, have an extremely low prior probability of being true.
Remaining skeptical of religious claims is the only logical approach.
It always amazes me how non-Christians still fall into mindless Christian apologism like this. I can only imagine your post is a Golden Mean Fallacy where you think, in order to be rational, you must be impartial between positions that are demonstrably wrong and the "extreme" of writing falsehood off completely. Sometimes claims are simply false.
