The editorial may have many errors, but I have some sympathy for the basic drift. What I mean is, how can we honestly quantify as in "5 days indulgence" or whatever?
Frankly, I think Christians go overboard when they begin to talk too specifically about the after-life. I whole-heartedly believe in it, of course, but to pretend to understand it, bally-wash!
My guess - and it's only a guess - is that the after-life is far removed from anything our earthly minds can imagine. This whole business of spending some time being punished in purgatory - hm - sorry, but it sounds hollow to me.
I recall a story of two monks who were good friends but disagreed when it came to heaven. Brother John pictured it as a place where those dwelling there spent eternally singing praises around the throne of God. Brother James, in contrast, said in effect: "That's like what we've been doing down here. When we get to heaven there will be dancing and singing. loads of fun!" They finally decided to stop arguing, but the first one to die would return and then they would know which one was right.
Brother John eventually died, and the very next night, as promised, he came to Brother James in a dream. Brother James, he said, we both were wrong. But I can't describe this place to you. It's totally different from what the finite mind can comprehend. But no reason to fear. You'll like it.
My guess is that that's the way it will be, and we should just stop silly speculation and leave it all in the hands of our loving God and Savior.
