....So I ask, on what basis does one know which passages are to be take literally and which are we free to spiritualize.....
Excellent question olegig. How does one avoid illegitimate spiritualizing? I love the saying, 'The new is in the old concealed, the old is in the new revealed'. I believe the saying had it's origin with Augustine. Anyway, I've found it to be so true and have derived immense pleasure in my personal Bible study for years from following that simple dictate.
How does one avoid illegitimate spiritualizing? IME, you should always first have what I call a 'pointer' to direct you to the passage. The Bible is pregnant with these pointers. Example:
In post #29, I take Mystery Babylon, the great city, to mean apostate Judaism. Why? How? I've a pointer given in 11:8:
And their dead bodies lie in the street of
the great city, which spiritually is called Sodom and Egypt,
where also their Lord was crucified.
There's actually FOUR points of comparison here, Babylon, Sodom, Egypt, and Jerusalem. Therein lies some astounding similes with what transpired during the wrath that came upon 'that generation'. It is my intent, the Lord willing, to share what I see in these as time goes along. You might find it interesting to know that while several prophecies are given in the OT concerning the destruction of Babylon, Babylon was never destroyed as described. It remained a viable city up until the eighth century A.D. when the river Euphrates changed course and left it sitting high and dry. Babylon faded away, it did not meet with the violent destruction as described. But those OT prophecies concerning Babylon very aptly describe what happened during the destruction of Jerusalem. Thus the term, Mystery Babylon?
Here's another pointer example:
And as Moses lifted up the serpent in the wilderness,
even so must the Son of man be lifted up; that whosoever believeth may in him have eternal life. Jn 3:14,15
And Jehovah said unto Moses, Make thee a fiery serpent, and set it upon a standard: and it shall come to pass, that every one that is bitten, when he seeth it, shall live. Nu 21:8
Note that the brazen serpent was lifted up for those that were bitten.
.........They that are whole have no need of a physician, but they that are sick: I came not to call the righteous, but sinners. Mk 2:17
It is the Spirit working within His children that causes them to feel their need for Him.
..........another example of regeneration before belief.
Fortunate indeed are those that have been made to feel the serpent's awful sting. Fortunate are those that hunger and thirst after righteousness.
I used a pointer here (to make my point):
......For
our passover also hath been sacrificed, even
Christ: 1 Cor 5:7
