there is no other way to understand prophecy or the written text unless you receive divine revelation.
Well then, since divine revelation is the key, here's mine--
I'm reading along in Daniel 4, and I see Nebuchadnezzar has a dream. Daniel interprets that dream, and tells the king that the point is: "Seven times will pass by for you until you acknowledge that the Most High is sovereign over the kingdoms of men and gives them to anyone he wishes." (v 26) I see this quite clearly and simply as God's humbling of the king. Then I read "All this happened to King Nebuchadnezzar." (v 28) I see this quite clearly and simply as the fulfillment of the dream. I read along some more and "At the end of that time, I, Nebuchadnezzar, raised my eyes toward heaven, and my sanity was restored. Then I praised the Most High; I honored and glorified him who lives forever...Now I, Nebuchadnezzar, praise and exalt and glorify the King of heaven, because everything he does is right and all his ways are just. And those who walk in pride he is able to humble." (vss 34-37). I see this quite clearly and simply as "lesson learned, end of episode."
Then I'm reading along in Luke 21, and see Jesus predict "They will fall by the sword and will be taken as prisoners to all the nations. Jerusalem will be trampled on by the Gentiles until the times of the Gentiles are fulfilled." (v 24) I see this quite clearly and simply as Jesus' prediction of the impending fall of Jerusalem, and that he says Israel will be trampled on until the Gentiles have had their day. I consult the history books, and lo and behold, Jerusalem WAS conquered a few decades later, and that the nation of Israel was not restored until almost 1900 years later. I see this quite clearly and simply as "prophecy fulfilled, end of episode."
There is nothing, absolutely NOTHING, that inspires me to connect Luke 21 and Dan 4, much less to concoct some convoluted fantastical arithmetic extrapolation about 7 symbolic times=7 symbolic years x 360 symbolic days per symbolic year = 2520 literal years, added to an uncertain starting date and ending with hypothetical speculations.
So much for my "McDonald's theology" .

Oh, and insofar as "authorities" are concerned: The preponderance of 19th-20th century commentary supports this dichotomy.
