Let’s put it this way. Imagine there are only two places, the Presence of God, and Deprivation of God. Imagine, too, that in order to get to the Presence of God, except for the case of a plenary indulgence, we have to travel through the place of Deprivation of God. For those souls who know they will someday reach the Presence of God, the suffering of deprivation is not as bad and for those souls who know they will never come to the Presence of God. For the first group, the place is Purgatory, but for the second group, the place is Hell. That’s how I see it anyway. Two places, three names.
If you stop and think about it, for many this world is a foretaste of Purgatory, and for many others, it’s a foretaste of Hell. At other times, earth may be a foretaste of Heaven. One place, three possibilities of perception. The difference I see is that when I suffer in this life, I have hope in the next, but the confirmed reprobate or atheist, when he suffers, he has no hope in the next.
When I suffer in this life, I can offer it up, turning my suffering into a joyful service to the Lord. I hope the poor souls in Purgatory can do the same, although they cannot pray for themselves.
