I'm quite familiar with the fact that God himself is outside of time, this is very easy to show through scripture.
However it seems to be an increasingly popular conception that there is no time in heaven as well. For example, in this answer about saints. (Probably not the best example, but readily available.)
I'm quite certain that time works differently there as we have many examples from scripture where future and past events in heaven are participated in. But a lot of people are explaining it in a way that makes man eternal (not just living forever but, existing eternally as God does in every time frame). I have also heard some Mormons say they were always taught man will become eternal too (don't know if this is official, just what I have heard some say).
This seems to me to create a problem with the fact that Satan was supposed to have been cast out of heaven, but by necessity is still in heaven if there is, in fact, no time. Even if we dismiss the depictions in scripture of time passing in heaven as metaphorical, in order to help us understand certain things.
How widespread is this doctrine and where did it originate? Does any whole tradition hold this view, or is it simply a failure of individuals to communicate their meaning?
