Liz Catholics believe purgatory is a part of the salvation process. While they may say the people in purgatory are "saved" they aren't completely saved or they wouldn't be in purgatory. Purgatory has to do with a person's eternal destiny.Yes, well, I have met several Catholics who would say exactly the same thing of purgatory - they emphasise most strongly that those in purgatory ARE SAVED. SO I repeat, what's the difference - apart from duration?
The gospel of the kingdom doesn't have anything to do with a person's eternal destiny.
Hope that helps.
