There are plenty of things that reason can't penetrate. You can't know the origins in epistemological sense of knowledge. Likewise, you can't know the past in epistemological sense of knowledge. All of these rest in the realm of faith, whether you like the idea or not. You have to trust that the author's sources are correct, and that sources of the sources are correct, and the sources of the sources of the sources are correct.
Because reason cannot penetrate everything, I think it is more honest to say that we don't know and to be suspicious of fantastical claims. Since I have never observed the types of things described in the early church and since I see people today make up fantastical stories that aren't true about religious figures, but a lot of people believe, it seems more likely that they were made up in the early church as well. There is enough evidence present to doubt the claims of authorship and the claims of miraculous events.
Extraordinary claims require extraordinary evidence.
Yet, for some odd reason you accept these with absolute certainty and you criticize the absolute certainty of Christian reasoning. Don't you see a certain duplicity in it all? Wouldn't you agree that our worldview would attract certain thing that we want to believe in? That's why I can't say for certain that what I know is true. But I can say for certain that these are the things that I ACCEPT AS TRUTH, based on my existent knowledge.
I don't accept anything with absolute certainty. Like I said, there is enough evidence there to seriously doubt the accuracy of early Christian claims. It has nothing to do with what I want to believe. You can tell me that the sky is really green, but no matter how hard I try, even if I wanted to, I would not believe the sky to be green.
I don't believe the claims of the Bible because they are no longer believable to me. And there has been no Christian apologetic that honestly addresses most of the serious problems with these claims.
Christianity must rely on fear for most of its persuasion. There is a lot of Pascal's wager type of thing. What if it was true? To me, that's the greatest source of doubt for me. It's hypocritical to say its based on love, when its very reason for existing is the fear of punishment for not being a Christian.
Another common theme that I find when reading the above described people, is that they are quickly to dismiss the "Religious myths", yet they are as quick to adopt the "New Age" like perceptions that have very little underlying support for these. And they derive the ideas from shamanism and experiences that are much more far fetched than Christian thought IMO.
Well, I see no difference other than a lot of "New Age" stuff tends to lay off the hell and brimstone. And maybe that's why its so attractive. Personally, I think its because people haven't learned how to live with mystery.
I have to admit that the inner journey is an interesting one, but I think its a mistake to start a new religion just because I might have a transformative inner journey. I think these experiences happen all the time, in spite of religion.
So, please satisfy my curiosity and tell me what exactly is it you are planning to accomplish here?
If I was to state my core goal, it would be to reduce suffering. I believe that fear based belief systems are immature at best, and have the potential to create great harm if left unchallenged. I think history attests to this over and over, particularly among those belief systems that claim certainty.
When these belief systems come to power, no reason and many times, no force, can change their harmful influences. At least a tyrant will respond to threats of force. Belief marches on even unto death.
