Oh dear. I've just seen this. And of course the way it has been reported makes a nonsense of the idea.
I can't find it, and haven't the time anyway, but we had a discussion of sorts on here some months ago and I attempted to shed a little light on the concept.
I'm sure I failed.
But essentially the idea of purgatory is that it enables a person to enter into the fullness of the love of God. How or what that means doesn't matter. God is beyond time and space so how can we know.
Yes, indulgences are bizarre. I think of them as rather like getting an CBE from Her Mag. It doesn't change anything, it doesn't really mean anything. But it's tradition and lots of people like it.
From what I can read between the lines the context is that any Catholic who turns, even momentarily, away from materialistic and selfish concerns, will become closer to God. That is, less selfish and focussed on the poor, which, so far, seems to have been the theme of Pope Francis' ministry.
