How is novel Attic’s a parable?

How is novel Attic’s a parable and how is it related to the biblical stories of Lazarus and of the prodigal son?
Some of my ideas ( The central intriguing theme of this novel is the exploration of one of the most compelling mysteries: the sorrowful and abiding love of a father for his son, no matter what. “Atticus” is a play on the parable of the prodigal son, also combined certain parts from the story of Lazarus where Lazarus raised from the dead similar Father Atticus meets his lost child. The novel is deeply rooted in the biblical stories of Lazarus and the prodigal son. )
