Final answer:
Revelation is considered a prophetic letter, which is a subgenre of creative nonfiction containing apocalyptic literature elements.
Step-by-step explanation:
The literary genre of Revelation, which is the final book of the New Testament in the Bible, is best described as a prophetic letter. This genre is a form of creative nonfiction that blends visions, prophecies, and messages from God with a letter format, addressed to a specific audience. In literature, while there are four major genres—poetry, drama, fiction, and creative nonfiction—each with its subgenres, Revelation does not fit neatly into one of these. Instead, it is considered a piece of apocalyptic literature, which is a subgenre that involves revealing to humans a God-eye view of the truth that is hidden from the normal human perspective. This form of literature often includes vivid symbolism and discusses eschatological themes—the end of time, judgment, and the ultimate destiny of humanity.
The characteristics of Revelation include symbolic imagery, prophetic declarations, and ethical teachings. Within the context of the New Testament, it shares elements with other prophetic books and letters; therefore, reflecting its purpose, culture, and expectation of the time. The text does not align with being a law, history, or poem, although it may contain poetic elements within its detailed and symbolic visions.
