I am sorry if I was the reason why the thread deviated friom its original title and course.
My point, as close to the topic as possible, is that it is not clear to me whether Bishop Wright was correct or not.
On the one hand, yes, we, the Orthodox, seem to believe unanimously that God created ONE world and that THIS ONE world is being saved, redeemed, restored by Christ. So, we are not dreaming about some kind of travel to another universe when we die; rather, we have a hope that after our temporary physical death, we will rise with Christ to live eternally in this same God-created world, and in this world we will be God's fellow workers (συνεργοι).
On the other hand, there are indications in Scripture and Fathers that our experience after the general resurrection of the dead will be very different from our present experience. What it will be, precisely, we do not know, but we know that it will be different. Maybe, indeed, the Earth and other planets and stars and galaxies will just disappear, and maybe, indeed, we will have no limitations not only in time (eternal life), but also in space, the way Christ seems to have no spatial limitations now. So, what exactly will be our role after the Resurrection, what shall we be doing, in what exact way shall we be God's συνεργοι, is an open question. In a way, perhaps, Christians are both wrong about Heaven, and right.
