Belief As Serious Fiction, Ctd

Norm Geras complicates my thoughts on religious practice and belief:

Andrew speaks of beliefs of a kind that haven't been at the centre of my mind in writing about this question; such as the belief that 'the Blessed Virgin was… transported into the sky rather than dying' – one, I have to confess, I wasn't aware of. However, in questioning the thesis that belief isn't a crucial part of what religion is about, I had in mind more 'mainstream' beliefs, such as the beliefs that there is a God, that this God has certain characteristics and enjoins certain ways of being and doing, the belief in the immortality of the soul, and so forth.

Here, just today, I read that a Scottish rugby player, Euan Murray, believes that 'the Bible is the word of God' and he will not play rugby on the Sabbath on that account. Well, is this a belief or not? It is associated with a practice, no question about it: the practice of observing the Sabbath. But how can the bible be the word of God if there is no God or if there is one but He doesn't have any words? How can Euan Murray's practice of not playing rugby on the Sabbath be made sense of if we treat his beliefs as merely marginal or of no consequence?
