The purgatory concept is based on a human view of 1 Cor 3:12-13 and other passages having to do with various kinds of judgment encounters with Jesus in eternity.
My read: Because we will go into eternity short of completed actualization of reconciliation (we are reconciled in status) there will be a final encounter where all is squared between our souls and the gracious, all-forgiving, but never excusing Lord. This is where He will dry our tears; we will weep at the realization of how we disappointed the Lord, as well as in the realized comfort of the reconciling Lord. The heavenly Kleenex folks will have big business here, if I can use such a light hearted metaphor. If this is a “purgatory” we would be stupid to shy away from it. But I understand it as more of a final reconciling moment.
Catholicism teaches that purgatory is where the final purification from sins not confessed occurs through suffering.
It is totally unscriptural because without the shedding of blood there is no forgiveness of sins and where there is forgiveness, there remains no more sacrifice.
No one can be cleansed from sin by suffering.
If there is sin credited to your account when you die, tough lock. You are not saved and no amount of torment in anywhere can change that.
I would love to see the scriptural support for that. As I have read scripture there will be no tears or pain there.
