Casey is surprised about this story that reports of Pope Benedict XVI offering relief from purgatory to Roman Catholics who travel to Lourdes over the next year. I thought that it might help to show this diagram and the following excerpt from catholic.com:

The Catechism of the Catholic Church defines purgatory as a "purification, so as to achieve the holiness necessary to enter the joy of heaven," which is experienced by those "who die in God’s grace and friendship, but still imperfectly purified" (CCC 1030). It notes that "this final purification of the elect . . . is entirely different from the punishment of the damned" (CCC 1031).From Wikipedia:
The purification is necessary because, as Scripture teaches, nothing unclean will enter the presence of God in heaven (Rev. 21:27) and, while we may die with our mortal sins forgiven, there can still be many impurities in us, specifically venial sins and the temporal punishment due to sins already forgiven.
Mortal sin, according to the beliefs of Roman Catholicism, is a sin that, unless confessed and absolved (or at least sacramental confession is willed if not available), condemns a person's soul to Hell after death. The phrase is used in I John 5.16 -17:I am not an expert in this but thought that it would be helpful to understand this theological difference when discussing the afterlife with our Roman Catholic brothers and sisters.. and please do not use this post as an opportunity to bash Catholicism.. though Luther objected to the selling of indulgences.. we Protestants have our own issues around the raising of money.
"If you see your brother or sister committing what is not a mortal sin, you will ask, and God will give life to such a one - to those whose sin is not mortal. There is sin that is mortal; I do not say you should pray about that. All wrongdoing is sin, but there is sin that is not mortal." (NRSV)In all Catholic moral theology, a mortal sin, as distinct from a venial sin, must meet all of the following conditions:
Its subject must be a grave (or serious) matter;
It must be committed with full knowledge, both of the sin and of the gravity of the offense;
It must be committed with deliberate and complete consent.
