It has nothing to do with lack of faith in "complete forgiveness." First, everyone in Purgatory is already completely forgiven. Nobody is claiming they can get "more forgiven" through our "works" apart from Christ.
Second, none of our prayers are "apart from Christ." They are all within the Body of Christ, 'in whom we live and move and have our being'. Prayers or works apart from Christ would be a complete absurdity, something like breathing without air.
Third, we all know this forgiveness was granted to these departed souls through their faith in Him, and only Him. Only He can forgive sins.
So what you attributed to Catholics as "lack of faith" is false.
Do you wear the miraculous medal?
Should be a simple yes or no answer to each.
If everyone in purgatory is COMPLETELY forgiven, then what the heck are they in purgatory for?
Purgatory is only for people who are NOT completely forgiven.
If you are completely forgiven, there is no payment or accountability left for sin.
The slate has been wiped clean.
It's gone.
Done.
Never to be remembered again.
That's what forgiveness is.
If there's any atonement, accountability, payment, anything one has to do for something that was done, then it is NOT forgiven.
Perhaps you have me mixed up with someone else. I can't seem to find the post where I stated this. One either has faith in the saving works of Christ or one doesn't.
I do not question people's faith. What is VERY important in my mind is for all of us to have sound doctrine.
