Hi Jean!
It sounds like you know very little about Purgatory. It’s probably best to say nothing until you have at least educated yourself just a little bit - doncha think? Read this from the Library section at the top of the page:
catholic.com/library/Purgatory.asp
Sudden and unexpected death might not allow for repenting of all sins in this life. Just as a thought experiment, what do you think happens to the sins of those who die suddenly and unexpectedly - before they have an opportunity to repent?
Here are your choices:
A) They are not forgiven because they were not repented of.
B) They are forgiven even if they arent repented of - we dont really need to repent to be forgiven!
C) There is a form of repentence which can occur after death and that is how they are forgiven.
Please be sure to include some irrefutable bible verses to support whatever your position happens to be…
