What is the author's style in The Second Coming by Walker Percy?

The novel is written in the first person omniscient point of view; as early as page 9 the narrator refers to him or herself as "I" in a metafictional construction. The unnamed, unknown narrator is authoritative, consistent, and reliable. The first person narrator, however, is completely effaced by the text and does not occur as a significant character or participant in the events described in the novel. Strangely and enjoyably, the narrator also does not intrude in the narrative construction. This causes the text to be read as if it were constructed from a more traditional third person point of view even as infrequent and subtle but notable intrusions of the first person narrator occur.
