I don't believe in an eternal place that is impossible to escape.
I also think that the whole Purgatory hellish sin-purge thing is outdated and totally negates the power of God.
God CAN handle "impurity." It's not what goes in, it's what comes out. Jesus said so himself. We don't need to be cleansed for a billion years just so we can be in the presence of God. What, did Jesus only feel safe to be around imperfect unbathed humans because he had the human flesh barrier between him and his godliness?
Do we presume to assert that his skin and muscles and fingernails and organs and blood vessels and bodily fluids were not also in some way "God"?
If we must be purged, I think we do it here. For me, it's pretty literal. When I'm letting go of something rather toxic in my psyche, or going through a big transition, I tend to have at least one rather horribly violent vomit session.
I see neither a logical nor intuitive connection between the loving, perfect God, and the need for us to be squeaky clean in order to achieve "salvation" (another term with all sorts of interesting definitions).
Peace and all good.
