Spiritual tone is achieved through word choice (dedicate, consecrate, hallow) and parallel syntax structure (we cannot dedicate, we cannot consecrate, we cannot hallow).
An allusion is a type of writing that makes a reference to a person, place or event, it can be real or imaginary, it depends.
Allegories are like metaphors, they bring hidden meanings in figures, actions, imagery, or events, which creates a moral or spiritual meaning the author tries to show.
