And what do you mean by "there is none of it today"? Jut because you haven't seen it or experienced it doesn't mean it isn't there.
Evidence isn't proof, all it is is some form of data which can be in the form of someone claiming this or that but then there is a process of seeing if it is good, solid evidence which can be verified or not. That was my point, all Christianity has are these claims to faith which are nothing but rhetoric, which anyone could do, not solid verifiable data. Your most 'solid' evidence for your faith, which is decidedly 'gaseous', are you books/manuscripts of the Bible.
As for evidence of the none materialistic kind as I have pointed out above you don't really have any, none that will support your faith. As for me for having 'seeing' it; as you say, or not I have seen the phenomena of the Unconscious (i.e. of the Jungian school type) and it is from this that the secondary phenomena of religion stems from. Religion supervenes on the Unconscious and is merely symbolic. And you should also note, following this, that your approach to the evidence for your faith gives rise to every other religion that has shown its face on this planet whether extant today or defunct and no longer practiced.
Whilst I would agree in part, JK - and there are millions of people who do live in "those times and experience those events, fully immersed in the times, ethos and culture" I would also suggest that, for all the advances that the West have made over the centuries, human nature is pretty well the same now as it was then. We simply live in a rather more formalised way; so that the rich get richer through government design as opposed to government disinterest; and the poor get poorer through the same mechanisms.
"People do live in those time...."
You can only do that if you go back in time (and place) and be born into those days, 2000 years ago. No one can do that!!!
As for your claim of our natures being the same, it is about ideas, cultures etc. not the human nature in its more basic components. If it was that easy then we would have no trouble understanding ISIS and other cultures. This was more true in the past, because the internet etc. has homogenised our world more, and it was because of this that many wars started for the very fact of the differences and fears this creates. So you can have nearly absolutely no idea what it was like to live 2000 years ago or to understand how they thought or felt or perceived the world around them and themselves.
For example, people are living through a war in Syria today and even though you can see it on the news etc. you have no idea what it is like for them, even though it is happening in your life time. The only way you could
really know what they are going through is to live in a war zone in your homeland, seeing your home and who life and culture being destroyed. Imagination and information is not enough only total experience of it is!!!
As a Christian, I believe that what God offers humanity is a fulfilled and worthwhile existence based on what I believe to be the purpose of the natural world. You are at liberty to disregard that, but Christians don't force people to act in given ways - or at least they don't if they are following God's teachings as expressed by Jesus.
That is why I differentiate between Christianity and churchianity.
That is your culture and community ethos, and that is as far as it goes i.e. all those claims of heaven's rewards, JC coming back etc. etc. is just tacked on to add that numinous quality that all cultures and societies tend to do because of our relationship with the Unconscious, that include the instincts and our human nature etc.
