Can God change the past?
IF I believed God could change the past I’d be on my knees praying for him to undo the Holocaust. (The Holocaust is on my mind because this evening I am going to hear some theologians and biblical scholars talk about it.)
But, if the fact that God cannot change the past (which most Christians agree he cannot) does not “limit God,” how does saying that God cannot know some portion of the future limit God? It would seem to me that, logically, God’s glory is just as much at stake in his ability to change the past as know the future exhaustively and infallibly including events that are yet to be determined.
Perhaps the real issue between classical theists and open theists is the nature of the future and NOT the nature of God. Greg Boyd has been pushing this point very strongly for years. And yet his critics continue to accuse him and other open theists of limiting God and depicting God as less glorious. I suspect those critics would agree with the Calvinist philosopher I mentioned at the beginning of this post. I think I see an inconsistency, if not hypocrisy, in this.
What do you think? Can God change the past? If so, why is there no example of it in Scripture? (I’m not talking about God forgiving past sins or anything like that. I’m talking about God literally undoing events that did happen.) And, to those who say God can change the past I ask whether they pray for him to do so? And, if God cannot change the past, how is that not a limitation of his power? And, if it’s not, then why is saying that God cannot know future events that are now undetermined?
Not long ago I heard a well-known open theist present a paper arguing that open theism does not in any way limit God. It does not even say God limits himself. The question is, of course, what constitutes a “limitation?” What do you think? Is it possible to say that even open theism does not “limit God” or even portray God as self-limiting? (I have customarily explained to people that open theist says God limits himself.)

Last (?) thoughts (for now) on God changing the past (or not)
posted February 2011
So, here is where I have come to on this subject as a result of the discussion happening here (which I invited). MOST (not all) respondents agree that God cannot change the past because of the NATURE of the past. Those who said God would not change the past because he foreordained it missed my point. My question was not about “would” but “can.” The Calvinist philosopher I mentioned (who denied that God can change the past) did not appeal to foreordination. He simply stated that God cannot change the past because the past is what already happened. Thus he was appealing to logic.

He simply stated that God cannot change the past because the past is what already happened. Thus he was appealing to logic.
The strongest argument I have read here (or anywhere) against God being able to change the past AND that [is] not “limiting God” is that "to change a past event is to undo that which one is changing, which means not changing it." For example, if God “went back” (as it were) and undid the holocaust it would make it the case that the holocaust never happened and therefore God would have nothing to “go back” (metaphorically speaking) and undo. So, changing the past seems (in spite of movies) to be absurd. That God cannot do it is no more a limitation of God’s omnipotence than the fact that he cannot create a rock so heavy he cannot lift it.
Here’s my point all along: IF it is the case that God’s inability to change the past has to do with the nature of the past and not at all with any limitation of God’s glory or power, WHY would it [be] the case that God’s inability to know future, undetermined events (i.e., decisions and actions of free creatures) limits God’s glory or power or even omniscience? Isn’t that claim like saying that God’s lack of knowledge of the DNA of unicorns diminishes his power and glory? Or, more to the point, how does it differ from saying that God’s inability to change the past limits his power and glory?
In short, if it is the case that God’s inability to change the past, because of the nature of the past, does not affect God’s glory and power, why would it be the case that God’s inability to know the future exhaustively and infallibly affects God’s glory and power insofar as the future is partly unsettled?
Now, PLEASE stay on track with me here. The discussion is NOT about God’s sovereignty at this point. To raise the issue of God’s providential sovereignty and claim that saying God’s inability to know the unsettled future limits God’s sovereignty is to veer off topic and raise a separate issue.
IF someone argues that for God to be all glorious and all powerful he MUST foreordain and determine everything past, present and future he or she raises a different set of questions. What I am asking here is only this: IF it is the case that God logically cannot change the past without that in any way diminishing his glory and power HOW is it the case that an inability to know the future exhaustively and infallibly diminishes his glory and power insofar as knowing the future exhaustively and infallibly is logically impossible?
In terms of “cash value” here is my point. Many Calvinists (and perhaps others) claim that open theism especially diminishes God’s glory. (Some Calvinists claim that open theists are not even Christians!) Those same Calvinists probably believe God cannot change the past (logically). But open theism claims that God cannot know the future exhaustively and infallibly because of the nature of the future–not because of any inherent limitation in God (including self-limitation except insofar as God created a world where he could not know the future exhaustively and infallibly).
Now, of course, as I said earlier, IF a Calvinist changes the subject to claim that ALL non-deterministic theologies diminish God’s glory and power, that’s another debate. Then not only open theists but classical Arminians, many Lutherans, most Catholics, probably all Anabaptists and many other Christians are diminishing God’s power and glory. But Calvinist critics seem to aim primarily, if not exclusively, at open theism as especially limiting God’s glory and power. But how so? How is the open theist’s view of God and the future any MORE diminishing God’s glory and power than any garden variety non-deterministic theology?
Doesn’t this prove that the debate specifically over open theism is NOT over God but over the nature of the future just as the debate over God’s power over the past is NOT over God but over the nature of the past?
