My previous post on Nikki Gumbel's removal of 'when' from history and giving it to science (he means, of course physical science, as history is a 'science' in that it seeks knowledge) left a gap: the gap was about time itself and its place in the Genesis narrative. I've already dealt with this from one perspective, but there is another I want to bring here.
The presumption that the time markers in Genesis are not germane to the revelation derives from an implicit physicalism: an ontological error that parts company with both the dualism of the Bible, and its concrete realism. Because it presumes that time is a 'given' its action within creation is not recognised and thus the error also parts company with time's existential dependence: that 'word' has priority. Moreover, 'word' strictly in the John 1:1-3 sense. Not a logos of the Greek kind, but the word as going out from the love of God as triune communion of unified will.
Time is integral to the revelation as a created thing, and the markers of time in the creation passage show not only that God orders within time, but uses time to bring order; he using time as the domain of fellowship within the creation (I don't know how the new creation will work in this connection...we'll have to wait and see) where it provides a shared constraint-space definitional of event sequence. Time forms the event-space in which we can join in relationship. Indeed, in which we are shown that the event-space is God's and is where he joins us in relationship.
To put this to one side is firstly a hermeneutical arrogance, then it treats time as an 'accident' of material, almost putting it behind God and not an essential part of the revelation. If God use the time markers as simply symbolic of something else ('what' is never canvassed), one would have to wonder at the specificity of the markers, the deliberation of the pace of creation, the connection formed by his people Israel reflecting his creation and use of time having their life pattern reflect God's.
But, time has to be signficant, and more than symbolic theologically (because the language denies a symbolic role and requires a concrete role for it), as time is our universal constraint: it dominates everything that we do and think; it is inescapable.
Physicalism evacuates time of its theological significance. The proponents fall back to the implicit materialism. Their reference to a paganised framework of understanding (that there are universal givens apart from God) this entails is a theological embarrasment.
