I belong to a church that is in communion with the bishop of Rome
From what I understand, as others have expressed, there is no where God is not.
Think Pascha: we sing "Christ is risen from the dead, by death he conquered death..."
He is victorious even over hell.
Those who have passed from this life into the life eternal are present with God. For those who turn from God, this presence will be experienced as pain. It is a fire that either burns with pain or with joy.
There have been stories told by the Desert Fathers of sinful individuals being released from Hell because of the prayers of the faithful.
I have heard of modern monks on Mt. Athos professing the same thing.
I also know personally members of both the EC and EO communities who believe that in the end Christ will reconcile all things to Himself. I personally think it is possible, and hope for it, but of course do not take it for granted.
Honestly, TL (and others), the best way to learn about true, unadulterated EO teaching: read the liturgies of the church. Not just the DL, though that is a good start, but all the prayers of the hours around the church calender. That is where the theology lives in its ancient form.
I would also recommend the book: Mountain of Silence. It is written by a man from Cyprus who becomes agnostic after coming the US to study, then returns to his home island as a part of a sociological study (he is a professor in Maine) and begins to speak with a monk about the basics of Orthodox spirituality. It is a wonderful introduction and simplifies concepts into easy to understand language. He covers everything from the purpose of the church, angels, demons, sin, prayers for the dead, and more. I loved it.
As far as reconciling Eastern perception with western perception, well, for the first thousand years they more or less existed side by side. The differences in theology have been there. Like I said, the theology is contained in our liturgy, and the DL has been around since at least the 5th century AD. I personally think that the Latins get a little too into the whole 'fire and brimstone' idea, but that is a topic for another thread. The actual theology as professed by the Latin church, afaik, does not get so doom and gloom and so leaves room for the two to exist side by side. Honestly, the already do, if you take into account the number of people I know who ascribe to authentic Eastern theology while remaining in communion. There is hope yet.
