A literal reading of the bible recognizes legitimate symbology.
Excellent point you make!!! The symbol isn't there just to fill space or for navel gazing; it represents a real message or a real person/place/thing/event.
Amen!
There are at least 6 ways to mess up scripture.
One, adding to the word of God
Two, subtracting.
Three, interpretating something to be figurative when it is literal
four, interpretating something literal when it should be interpretated figuratively
Five, dropping the context.
Six, not obeying the truth that has been already revealed to you. (See Ezek.14:4)
