It’s not something that he brought to this world.
But what he brought was powerful and radical enough to slowly and eventually overcome many of the terrible animal-like human traits. Christian societies were the first that got rid of slavery, introduced human rights, democracy etc.
Yes, it took a long time to unravel and it’s not a finished process, but it’s not something that just happened. What feel natural for us today was not natural at all back then.
All critical ethical ideas that modern western civilization is based were either invented or popularized by that guy in some unique and unprecedented way.
I challenge you to provide one thing that jesus introduced. It turns out, EVERYTHING he taught already existed. I can paste a table of data, but ai is cleaner and faster.
And democracy is _famously_ Greek. Over half six hundred years before Jesus lived.
His historical impact comes less from novelty and more from narrative power, charismatic delivery, and, later, institutional amplification. And it is largely Paul who should be credited for amplification.
Show me other religion that taught to love your enemies and survived to these days at the same time. Just a tiny example of why you totally miss the point by not seeing how innovative was his ethical approach for that time. And yes, one of his great achievements is that he succeeded to make those simple and already existed ideas popular. This is novelty by itself.
