Upon reflection I see your point about Niggle already being saved. This does make sense.
"the Church does not believe that Purgatory is a second chance, but a final cleaning off for the saved before they enter Heaven. This was also C. S. Lewis's view of Purgatory."
Please post some information on Lewis' view of purgatory. This is dissapointing to hear. I do not believe this concept is very scriptural.
Thank you,
