In the case of Ezekiel, however, the entire book is a presentation of God's holiness and his anger/hatred of sin. From Judah to Israel, to Babylon to Tyre to Sidon to Edom to Egypt, etc, the book speaks of historical figures and nations whom God will judge. It is important to understand this before jumping into other speculative interpretations.
In Revelation did the churches actually exist to whom a letter is written? Mounce does a fantastic job in his commentary of the churches in Revelation. He shows the historic references Jesus uses in addressing the churches. He rejects the "ages of the church" theory, that so many evangelicals believe, by showing the historicity of the letters to the specific time. There is no need to create some fantasy that is not provided in the text.
