It's not necessary to split these hermeneutical hairs for two reasons:
1. The debate is over whether Jesus spoke literally or symbolically, not whether the symbolism best fits the definition of fable, allegory, or parable.
2. Our focus should be figuring out why Jesus would say these dead men were in possession of their resurrection bodies THOUSANDS OF YEARS BEFORE He and others taught collectively of the time when the dead receive them, as well as other contradictions which arise if we make this story literal.
If square peg theology don't fit, Immortal Soul doctrine, you must quit.
Our focus should be on "WHAT IS THE LESSON?" And it is fairly impossible to miss it.
The main point is that the Bible warns people about a judgment awaiting those who don't love MERCY toward their fellowman whom they have the power to help, and that the only way someone will heed this warning is to have faith and respect in the Word of God and align themselves accordingly in this life, then even if they see someone rise from the dead it won't have a lasting effect in reforming their actions.
Now if we can agree that, that is the main point and not what things are like in the afterlife, which is what I hear you saying, then we can stay FOCUSED on the main lesson.
As we stay FOCUSED on the main lesson and examine the text itself where this MAIN LESSON can be highlighted with a yellow marker, if you will, we clearly see that the WARNING is about a place of torment not all the other things you might try and put in the rich mans' mouth or head. He used words that reveal what he was thinking and what he wanted Lazarus to warn his brothers about. And this warning is what Abraham said Moses and the Prophets already contained.
The Parable lesson was...."if they won't believe the scriptures about
THIS PLACE OF TORMENT" then they won't believe if Lazarus came back from the dead and shocked them with a supernatural appearance and
"Warned them about the place of Torment" that awaited them. Wasn't that the plain meaning of the PARABLE? How could it mean anything but that in parable form?
If you asked a school child in first century Israel. "what is the lesson of this parable" having taught them how to identify the main lesson in a parable, they would be able to highlight this section below in red.
‘Then I beg you, father, to send him to my father’s house—
28for I have five brothers—so that he may warn them, lest they also come into this place of torment.’
29But Abraham said, ‘They have Moses and the Prophets; let them hear them.’
30And he said, ‘No, father Abraham, but if someone goes to them from the dead, they will repent.’
31He said to him, ‘
If they do not hear Moses and the Prophets, neither will they be convinced if someone should rise from the dead.’”
Now if that is the lesson, then it must include the subject of the warning that Abraham is saying can be found in the writings of Moses and the Prophets. that he may warn them, lest they also come into this place of torment.
It is impossible to say that Abraham was saying that if they read Moses and the Prophets they will be warned about soul sleep. No, if they read Moses and the Prophets they will be warned about THIS PLACE OF TORMENT.
