I believe that B-16 actually hints at hell in his new Encyclical on Hope in his introduction...
“SPE SALVI facti sumus”—in hope we were saved, says Saint Paul to the Romans, and likewise to us (Rom 8:24).
According to the Christian faith, “redemption”—salvation—is not simply a given.
Redemption is offered to us in the sense that we have been given hope, trustworthy hope, by virtue of which we can face our present: the present, even if it is arduous, can be lived and accepted if it leads towards a goal, if we can be sure of this goal, and if this goal is great enough to justify the effort of the journey.
And if we put in the right actions moving toward that goal. For example:
I could have a goal of reaching heaven, but I could currently be addicted to pornography, alcohol, gambling, etc. You name it.
Through addiction, haven’t we lost our hope? And are therefore moving into the realm of hell?
What if we repent of these sins and reform our lives, moving away from these addictions? Do we then have hope? Can we expect then to move more toward heaven than hell?
Fascinating to contemplate, isn’t it?
