I don't know if you also wanted to know what we meant by them so I'll try even tho' there might be disagreement about the exactness.In my opinion
is used with posts to remind us that we are not debating. This is a discussion forum and without the IMO, some forum participants come off as sounding like they have a corner on what God meant to say. That doesn't make for discussion/conversation but turns people off/angry.
Eternal torture/ eternal torment - This is a belief held by the majority of professing
Christians that God loves us but ONLY if we choose to trust in the shed blood of Jesus on the cross to cover our sins. This MUST be done before one dies or it will be Eternal torment/torture reserved for that individual.
Eternal death - this belief held by relatively few "professing" christians but by a majority of atheists is that if one does not trust in the shed blood of Jesus on the cross to cover our sins in this lifetime that when we die, we will be simply erased and go out of existence forever. The christians that believe this usually believe that there is also some kind of torment/torture before non-existance comes to pass.
Ultimate reconciliation - is the belief held by a minority of "professing" christians that the scriptures confirm our God is a God of love, justice, and mercy and that the shed blood of Christ covers ALL the sins of the whole world. Most people will not be saved in this lifetime though we are instructed to pray for the salvation of all men because God says it IS his will that ALL be saved. We believe that eventually, ultimately, all people will be reconciled to God and God will be ALL - in ALL as the scripture states. There will be varying degrees of temporary punishment because God is not mocked.
This is "corrective punishment" as never ending or eternal punishment serves no purpose. Finite sinful man cannot be punished infintely.
Well those IMO are the basics. There is no way I could cover every aspect of each as whole books are devoted to this. Books on each one of the three positions so this is a very brief explanation.
