By what I know, in the Bible, it is told when something is a parable and what it means.
I have understood that a parable is a type of metaphorical analogy. If the story of Lazarus is metaphorical analogy, from what it is a metaphorical analogy?
People who believe that a person has an immortal soul or spirit that either goes to heaven or a place of torment after death make the resurrection of the dead absurd and meaningless.
A person cannot be raised from the dead if he is not dead. It's just that simple.
The idea that people live on after they die was believed by many during Jesus' day and even long before that. However, if they believe what Moses and the Prophets had said then they wouldn't fall for that idea.
Moses did not teach about immortal souls going to heaven or a place of torment after death. Jesus says that Moses taught the resurrection of the dead.
The parable is directed toward the Pharisees and is based on the idea of souls or spirits going to heaven or a place of torment after death. The rich man class represents the Pharisees and the Lazarus class represent those who are poor but rich in faith.
The Pharisees were never interested in learning anything from Jesus. Their only interest was to catch him breaking the sabbath and have something to accuse him. And Jesus spoke in parables not to open their eyes but to keep them shut.
The parable is still working today on keeping shut the eyes of those who have not heeded Jesus' warning to beware of the doctrine of the Pharisees. But they have Moses and the Prophets. So let them hear them, if they can......but they can't.
