So there we have it. The bible is historically, scientifically, medically, morally, and psychologically inaccurate. It is a muddle of contradiction and confusion, written by pre-scientific, bronze-age tribesmen and religious zealots who made guesses about how the world worked. In almost every respect they got it wrong.

So what does this mean for the central premise of the book, its claim that the Creator of the universe, the Father of mankind speaks through it? Why should we suppose that when it gets everything else wrong, it manages to get this right?

We shouldn’t. The bible’s knowledge of God comes from the same source as the rest of its information: the wild imaginings of men who knew no better. The bible itself tell us so, many times. By its own admission, it is a catalogue of dreams, visions and inner ‘revelations’. In the New Testament alone there are at least twenty ‘meaningful’ fantasies of this sort, including the entirety of its final book, the aptly named ‘Revelation of St John’. The bible comes from an era when dreams and other subjective internal experiences were widely regarded to have significance as messages – revelations – from the gods, not the routine and not-so-routine workings of the human mind we now know them to be. Every era, before the scientific, regarded them in this way.

So Paul interpreted his psychotic episodes, depicted as a disembodied voice and bright light in Acts but far more dreamlike and hallucinatory in Paul’s own descriptions, as experiences of the risen Jesus himself (1 Corinthians 9.1 & Galatians 1.11-12) and of heaven (2 Corinthians 12.1-4). From these he built up all of his fanciful ideas of ‘the Christ’, not one of them based on anything demonstrable or real. All of them mere notions in his head, notions that others were all to willing to accept as the words of a god. After all, wasn’t that how the Almighty always communicated with mere mortals?

Still today people surrender to these ‘revelations’; Paul’s theology built on out-of-body experiences, the disciples’ grief-induced visions, John’s hallucinogenic ‘bad trip’. These are the foundation of Christianity as we have it, providing all we know of God, Christ and salvation, and all of them without any basis in reality. Some believers even claim to have the same sort of ‘revelations’ themselves; God speaking to them, Christ bathing them in light, visions of Heaven. All of these, again, entirely within their heads and no more real than the occasional appearances of my long dead grandfather in my own dreams. However much Christians might insist on a rational basis for their beliefs, it is an inescapable fact that the faith has its origins in ancient people’s dreams and hallucinations. Rationalising after the fact doesn’t alter this.

I don’t know about you, but I’m not interested in basing my life on others’ emotionally-induced inner visions, whether those of a Paul, or a Joseph Smith or a contemporary whack-job. I don’t want to learn about the world and life from people whose understanding and knowledge derive from their sub-conscious and hallucinatory fantasy life. Give me science any day, with its attempts to minimise subjective, human biases from its exploration of how things are. Give me its discoveries that have enhanced life, however imperfectly, in the here and now. Above all, give me honest rationality over sub-conscious imaginings and psychoses.

I have no interest in a god, or a saviour, constructed from other people’s dreams, visions or hallucinations, even, or especially, when they’re recorded in that most unreliable of sources, the bible.
