I believe from some things the Bible says that it’s possible for there to be some form of punishment for believers after death, what the Catholic Church teaches about it is too definite for the little that we know.
Jesus already paid for every sin Himself, as we could not, so there would have to be some other reason or reasons for there to be punishment for Christians after this life, but that’s far from clear, especially since we don’t know how God will judge the sins of Christians or really much of anything else. If a starving Christian mother once stole for her children rather than having faith and not stealing, will she suffer some set punishment for it after death? The Bible says “the last shall be first, and the first last,” in the Kingdom of Heaven. We can’t actually fully understand that or anything else that’s been revealed about the afterlife, so how can we judge that such a Christian will deserve such and such a punishment. It is all quite presumptuous.
There is answering for what you've done on earth, but that is NOT the same as losing your salvation.
Scripture makes it clear that born again believers stand before the judgment seat of Christ, but since they're there, it's not a matter of salvation. That's already settled by the fact that they are facing Christ.
It's to test their WORKS to see if they merit reward, not eternal life as it is already theirs, but reward for their faithfulness.
There is no paying off sin. It's paid in FULL. It's only rewards given, the icing on the cake.
There isn't "punishment" but a loss of "rewards". What these rewards are, we don't have much to go on, but I think there will be some regret and sorrow over what we could have accomplished for Christ and didn't because of our own wrong motives. There WILL come a time, though, that God will wipe away every tear from our eyes and the former things will be done away with, never to be remembered again. Whatever "crowns" we are given, we cast in the end at the feet of Jesus and proclaim, "Worthy are You, our Lord and our God, to receive glory and honor and power; for You created all things, and because of Your will they existed, and were created." (Rev. 4:10,11)
Could you POST these things?
If loss of some rewards is considered 'punishment'...
