Spiritualizing can never be equated with symbolizing by those who believe in the reality of the spiritual.
Jesus said, "The words I speak to you are Spirit..."
He did not mean symbolic, metaphoric, or allegorical.
The reason I don't answer your questions is because I'm busy on another project, but I check in here now and again. I don't have time for it right now.
Too bad you don't have the time to define terms, or ansywer my questions honestly wrt to how the Bible writers used symbols, etc. (What did circumcision of the foreskin symbolize?)
I take it you now believe that spiritualizing is OK in order to interpret the Bible. Progress is being made, although you still seem to resist the plain Bible teaching of the use of symbols, metaphors, etc.
Oh well, one step at a time.
