In terms of the bible stories, even if I was to write about something that happened 5 years ago, it wouldn't be fresh in my mind, and I may well misremember or exaggerate.
Yes, but whatever you'd be writing about from five years ago wouldn't have been kept live in a rigorous oral history passed down and told from one generation to the next, with stringent checks in place to ensure things are not twisted and exaggerated. Many things were passed down word for word. J Dunn's work on oral tradition in C1 Judaism is fascinating, the sheer amount of information people learned as story and then kept on retelling and retelling. It was as far from Chinese whispers as you can get because at each telling there would be a 'hold on, no, it's not that word, it's this one'... Also, the very earliest traditions and creeds were in wide circulation incredibly early and then recited as a community so it would be like Anglicans forgetting the Apostles Creed today - just couldn't happen once it was in regular use.
he was brought up being told he was the son of God,
Highly unlikely. In a good God-fearing Jewish family this would be tantamount to blasphemy, despite Mary's experience. It's clear that Jesus comes into his own understanding of his calling and identity, through his visit to the temple as a boy then his baptism as an adult when it is confirmed.
humans are pretty bloody impressionable. Especially when hope of something better is offered.
Very true!! But in this case they were being required to believe something completely outside of their experience and even their imagination. They couldn't have dreamed up the idea of a dying and rising Messiah, however much the Mithraism = Christianity proponents would like to lead you to believe. It simply wouldn't be in their narrative. And as for it offering something better - yes, hope, but in the meantime all it offered was sheer embarrassment and suffering, ostracizing from families etc. I know there's a case to be made for people who cling to a crazy wild belief out of a sense of belonging and ultimate purpose, but it's the massive numbers which are more convincing in this case. It's just utterly unprecedented - the other huge world religion was spread through military might, where Christianity was spread through generosity and love and most of all through events that actually happened in concrete reality within the experience of hundreds of eye witnesses.
as a non believer I've had some life affirming moments, moments of peace and clarity, lucky times etc, I can have these without the supernatural,
Yes, of course, and I never meant to play down those experiences at all. Everyone can have times of wonder, joy, awe, peace. Christians certainly don't have a monopoly on these. I was more trying to bring in the very transformative experiences, the impossible and miraculous as well as the day to day. And the void at the heart of us is something so many experience - we are looking to fill it with so many things and nothing quite fits. Augustine said that our hearts are restless until they find their rest in God and that it the experience of countless millions, though I do realise that many would contend with this - but it's my experience that the restless places in me are stilled in a profound way by the presence of God. And it's not just a happy moment or a fleeting sense of wonder at beauty - it's a lasting, incomprehensible sense of peace which goes far deeper than that. It soothes the void and seals the darkness in me.
we as humans think we are too special for that, but we are just advanced animals really.
I think we as humans think we are special because we are. I don't think there is anything arrogant in that. Our consciousness is quite incredible. Our sense of objective morality marks us out as creatures who have value and purpose. We know it is wrong to hurt a child because that child is imbued with value. We know it is wrong to oppress minorities because those people are imbued with value. We know it is right to defend the cause of the poor and oppressed because those people are imbued with value. Infinite, profound value which goes much beyond the evolutionary worldview of survival of the fittest and into the narrative of serving the other because of that value we see in them.
