It's called Song of Solomon/Song of Songs... Songs never include hyperbole or figures of speech eh?
:thumbs: You mean like metaphor?
Consider songs that are wholly allegory (which is merely an extended metaphor):
Morning Has Broken
This Old House
In the Garden
Psalm 23
etc. (these are just what pop into my head at the moment)
But marriage and nuptial pleasures, though actual events, are themselves allegory of God, Christ, the Holy Ghost and the Church.
And you couldn't really say that to your spouse? Really? My wife may not be literally flawless in body, or personality but I am able to quote 4:7 to her with a totally clear conscience because to me she is "all fair."
And you're fortunate. 1) Because you truly love her unconditionally, and love believes all things, (which is unlikely, as I have never met such a man) or 2) You love her because she is lovely despite the corruptions of the flesh (which I think is more likely, as, according to Solomon, it's the virtuous woman that a husband praises, and that is what I have seen without exception.)
And, I might add, that for women, growing old is ever more harsh on them, because to be seen as beautiful and dignified they must possess greater degrees of faith, virtue, knowledge, temperance, patience, godliness, kindness and charity than do men.
Just talking about the outward appearance of things. (Sorry, but that's the reality.)
So, for the Song to be universal, it has to be allegory. The physical features and ornaments in which the bridegroom delights metaphorical of graces and virtues.
