Well, if we're talking a story with a positive message, sure, I can get behind that.
If we're talking about historicity, though, it's hard to claim any reasonably evidence that that's what Jeshua bar Joseph actually preached. The quality of the sources is downright abysmal, by historian standards.
And then there's the question of whether the right sources even made it into the Bible.
There were a TON of alternative stories. And you can't dismiss all of them as just some very late fanfic. E.g., Papias falls somewhere between Luke and John, but he records a lot of stories about Jesus that aren't anywhere in the canonical gospels. And conversely, and perhaps even more suspiciously, for all his effort to basically be the first actual historiographer of Jesus (albeit, with a crap methodology) and gather information from all over the Middle East, he never seems to have heard of ANY of the stories that did make it into our gospels. So, anyway, if John makes the cut to be taken as a source in Bible Studies, shouldn't Papias be somwhere in there too?
He's not the only one. Infancy gospels as a genre started arguably even before Luke, and some date the gospel of Thomas before Luke AND even Matthew. In fact, some want it to be the mythical Q source. And they can be dismissed to be fanfic elaborating on Mark (although at least Thomas is different enough), but then the same can be said for Matthew and Luke too.
And it's not like they just have different spins on some common "dudes, be excellent to each other" theme. In fact some differ quite radically.
Take the gnostics for example. No, really, take them
It could get as different as the Cainites, for whom yeah, Cain was the real hero. It's like something out of White Wolf, to be honest.
Or then there's the Gospel Of Judas. It's not JUST that it's from a sect where Judas was the real disciple and favourite of Judas, the only one who was taught the true gnosis, but their whole belief system is... bizarre at the very least. And I bring it up because it ties into the whole, "yeah, but Jesus said to be excellent to each other" myth.
Well, these guys were basically Cainites or an offshoot thereof. Their cosmology started with a supreme divine being who created a perfect world called Pleroma (fullness or completeness) and populated it with basically the next rank of divine beings. Then one of these is somehow cast out, gets bored of sitting around in the void outside that Pleroma universe, and creates her own world and populates it with even less perfect divine beings. In fact, by this stage these are anything but perfect. They're more like what you'd call demons. And this still isn't our world. Then two of these guys, literally called Rebel and Fool create our world as basically a trap from which souls can't escape.
Except through the secret knowledge, i.e., gnosis. Told you they were gnostic. This is the actual message that Jesus came to give us, according to them. It has nothing to do with being excellent to each other HERE, but how to disobey the rules hard enough to get to the next level when you die.
It may sound bizarre by now, but remember these guys were worshipping Cain as their hero. We're talking about the first murderer.
So why would this guy be their hero? Well, not for any modern reasons like "believe in yourself instead of blindly obeying" or selecting the proper kind of sacrifice or anything. He's their hero BECAUSE he broke the rules. He's their hero BECAUSE he's a murderer.
Because, remember, this world was made basically by demons as a trap. The rules are given by that Fool demon, and are there to keep you trapped here. Breaking the rules is how you set yourself free.
So, long story short, take the 10 commandments and use them as a TO DO list. At least go do some adultery and coveting, if you don't have the stomach for the real hardcore stuff
Yeah, I imagine the recruiting drive must have been popular
But yeah, that's the kind of context in or from which THEIR Jesus came to save you.
