Fr. Frank:
This is not fully on topic, but since God promises us that He will not remember our sins, why will we remember them in
heaven?..
Hmm… but then this seems to fall into the “open theism” idea that the Protestants are into debating heavily nowadays – can an all-knowing God choose to NOT know something??? Technically, open theism’s big debate stems from the salvation/free will issue (ie, can an all-knowing and eternal God create beings with truly free wills and choose to not know what decisions they will make; can God, apart from the self-emptying
kenosis of His Incarnation, self-limit Himself and not know some aspects of the “future”?) I see your concept of Purgatory and Heaven being connected with this open theistic concept (please correct me if I am wrong!) in that you are also saying that God can self-limit Himself, particularly His
memory. (Can an eternal God
have a “memory”? Apart from Jesus’ human nature of course.)
From what I understand, the Church has rejected any notion of the open theism theory, on the basis that anything that limits God is potentially heretical. (Any Catholic theologians out there that can speak with more knowledge on this?) These comments on God truly forgetting sins seems to fall under the notion of open theism, and if so, and if open theism was rejected for those reasons, then this idea of Purgatory may also be questionable.
Secondly, I know that it does say that God promises that He will not remember our sins in the Bible, however, what is the official Church’s interpretation on that passage? Is it to be taken literally, or is it within the Church’s “interpretation boundaries” to consider that it might be stated in that way to refer to the fact that we have no need to worry about our past sins affecting us (ie, regret) in heaven? Now, I’m not promoting individual interpretation here, I’m just wondering if the Church has already spoken on this matter in the past.
You probably already realized this, but I should make sure to note that I am only speaking regarding
God’s not remembering our sins… Fr. Frank’s idea of ourselves not having memory of (or be unaware of the actual nature of) our sins in heaven I am able to accept. I can accept the idea that
we may “forget” , as a result of Purgatory/redemption–we are not God after all
In the end, though, does it matter whether we “know” whether or not we will either A) Remember our sins but not feel regret, or B) Not remember our sins but know we are forgiven them, in heaven?? Probably not—either way, I want to be there and not the fiery place (or “state of being” if you prefer!!

)!
As for Thomas Aquinas and what he has to say on this… offhand, I do not know of anywhere that he specifically addresses this issue, though I am sure he did somewhere, at least indirectly! I and others would greatly appreciate it if someone who does know this would enlighten the rest of us with references where to look!
