I shall first try to discuss this with you from the Catholic
point of view (on best effort basis only).
1) Given that the power to retain or release (let loose) was given
by Christ (who through His sheding of His precious blood on the
cross paid the price required for the atonment of our sins),
2) And that He had said (as recorded) that whatever is set loose on
earth will also be set loose in heaven.
I am of the opinion that as far as God is concern, its done, paid
in full by Christ our Lord.
as for purgatory, someone once told me that its for those
unabsolved sins, example; unintentional sins (some time we may do
the wrong things and we don't even know about it) ...etc or some
inperfections in our deeds that need to be purged before entering
heaven (NOTE: only for those who are already saved, and purgatory
is like a preparation zone).
Penance on the other hand is to make right, what is done wrong.
after prononcement of the sins had been absolved, the priest may
lead the person to do penance, it got be to return what is taken,
to go say sorry, to do some charity work, to recite the rosary
....etc, it not about making it right with God, but rather making
it right with Man (and in certain degree, Self).
OK.... this is according to my own understanding, maybe the more
knowledgable Catholic brethens can correct me.
***********************
From my personal understanding of the Protestant point of
view,
Christ had paid the price in full, His blood being both eternal and
permanent, is able to wash me clean.
So its
Get right with God (repentance, received forgiveness)
Get right with Man (go say sorry, make right the wrong things
...etc)
Its is that we know that we had make right with God (no more
condemnation from God) that we can face the punishment, or the
strength to make good the wrong deeds ...etc.
cheers.
