There are 6 conceivable views one could hold regarding God’s relationship to time:
1. God is timeless and time began
2. God is timeless and time didn’t begin
3. God is temporal and time began
4. God is temporal and time didn’t begin
5. God existed temporally without time and existed atemporally with time
6. God existed atemporally without time and existed temporally with time
5 and 6 are hybrid views which don’t get much attention, one of them for good reason, 5 seems pretty unlikely unless God existed in his own separate time before he created time and once he created time he became timeless. That is indeed a strange view. 6 is not so strange for it is plausible that God existed timelessly without creation but temporally with time. 3 is not very plausible either since that would imply that God came into existence with the first moment of time and thus would have a finite past history, thus violating his eternality.
So we are left with 1,2,4, and 6 as options available to the traditional theist. So which one is correct?
