Dear Paul and Simon,
As I understand it, the Church neither accepts nor denies apocatostasis. What the Church did condemn were certain parts of Origen's speculations that went along with this idea, such as the pre-existence of souls.
We cannot even pretend to know what God's will is here; it would be presumptuous to suppose we did. The Church has had pastoral problems with the doctrine of apocatostasis because of the obvious misreadings that can be made of it. But again, as I read things, we are not dispensed from the need to live a Christian life because of the possibility that all will be saved; by the same reasoning, all might not be - although on this I am with Simon, that that would be because of their inability to accept what theosis means.
In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. (1 John 4:10)
