**Does anyone know of a good reference that discusses the arguments both for and against time in Heaven?
I find that Catholics typically appeal to a timeless Heaven (Keating calls it the “perpetual Now”) while Protestants adhere to a temporal Heaven.
The notion of a timeless heaven certainly seems to answer some biblical quagmires:
1. Jesus saying to the thief on the cross next to Him “This day you will be with me in paradise” (Luke 23:42). Of course Christ did not enter into Heaven until 40 days after the Resurrection. Only if at the boundary of death do we enter into a timeless existence can we reconcile this promise.
2. Jesus saying “No one has ascended into heaven but he who descended from heaven, the Son of man.” (John 3:13, RSV). Note the use of the past tense form in reference to the Ascension – as if it had already occurred. Only if one thinks of the Ascension from the perspective of a timeless Heaven can this be so.
3. When the Gospels speak of Christ’s offering, they are addressing the “earthly” offering, i.e. His death on a cross. When Hebrews speaks of Christ’s offering, it is in reference to the “heavenly” offering made in the sanctuary of Heaven before God. The Bible sees these two offerings as one, simply viewed from different perspectives. Again, the “heavenly” offering could not have occurred prior to the bodily Ascension. Thus it is disjoint in time from the “earthly” offering – a contradiction unless Heaven exists beyond time.
In addition there are many philosophical and even scientific (if you start with the given of Heaven), that seem to reinforce the notion of a timeless Heaven. (I think the Kalam Argument is particularly compelling.)
Anyway, I have typically found that Protestants are willing to conclude that God exists beyond time but not Heaven itself – and definitely not any heavenly creature that inhabits the Kingdom. The scriptural passage most cited by the “temporalists” is:
 When he opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the witness they had borne;  they cried out with a loud voice, “O Sovereign Lord, holy and true, how long before thou wilt judge and avenge our blood on those who dwell upon the earth?”  Then they were each given a white robe and told to rest a little longer, until the number of their fellow servants and their brethren should be complete, who were to be killed as they themselves had been. (Revelation 6:9-11, RSV)
There is at least an implication here, though faint, that the saints experience time. Is this a viable rebuttal?
Your comments are welcome. My appolgies if this ground has been covered.
