Jesus made very specific demands on his followers and it's very clear when the scripture is an allegory or parable and when it's intended to be accepted as a historical account or a guide for daily living.
When it says we shouldn't eat rabbits, because they're unclean, because they chew their cud, it is not "symbolism". It's a Law.
When it says that a man who has sex with another man should be put to death, it is not an "allegory" trying to illustrate some vague truth. t was "God" saying "Homosexuality is an abomination, so much so that you should kill anyone who engages in it."
Most of the Parables start with Jesus telling a story almost like a joke, "There was a certain rich man.", "There were 2 brothers."
I don't see why there need be any confusion.....except for when Christians recoil at all the glaring sadism of "God", the blatantly false "science" and need a way to shut out the truth or have their cherished, and erroneous wolrd-view shattered.
