Codex Porphyrianus includes the only apocalyptic document in the New Testament that the name means what?
Codex Porphyrianus:  It is one of a few uncial manuscripts that include the Book of Revelation. Book of Revelation:  Its title is derived from the first word of the text, written in Koine Greek: "apokalypsis", meaning "unveiling" or "revelation" (before title pages and titles, books were commonly known by their first words, as is also the case of the Hebrew Five Books of Moses (Torah)). Book of Revelation:  The Book of Revelation is the only apocalyptic document in the New Testament canon (although there are short apocalyptic passages in various places in the Gospels and the Epistles).
