Doesn't this mean then that the Bible is a load of tosh then?
It depends what you would use it for, but I wouldn't say "tosh" in any circumstance.
As I said it is a partial record of the religious experiences of people from my religious heritage.
To paint an analogy you might listen to your parents and to some degree emulate their ideals and behaviour, however you are a different person and in some respects you will differ.
You wouldn't say that everything that your parents ever said was "tosh" but neither would you wish to be a clone of them, unless you thought they were perfect (which I accept that some Christians would argue about the bible).
