To interpret literature II

We were talking about René Girard's triangle, not a proper geometric triangle but a way to view relationships in a text, invented in 1965. Originally it was to show how two individuals in their relationship to the same object, idea, or position also have a relationship between each other. It was later developed to include the type of triangles that people are most prone to think about in a book or a film, the love triangle. But the triangle is much more fundamental than that.
In my own thoughts I began to imagine what interesting forms of topology you would get if you tried to identify all the possible triangles in a text. I started to get an image of many interconnected triangles to describe all the different possible relations. For more complicated stories it would of course not be possible to confine the triangles to just two dimensions, or even three. It is apparent that I am heavily influenced by my background in science.
Our teacher was talking about the triangle and invented an example with a man, a woman and the Bible. She explained how the man's understanding and relationship to the woman was influenced by a book that divide women in two groups Madonna or whore. And the book tell the man that the Madonna is good and desirable while the whore is bad and contemptible.
Now it wasn't the time to get into a long discussion outside the topic, but in my mind I did object to her example. I was surprised that someone that studies literature would use that kind of wording. If she had said “the church” instead of “the Bible” I would have understood it better. Because it is possible to find times and places where the church has indeed interpreted the Bible in this way. It is not even difficult to find these times and places. I would have thought that someone who studies literature would know the difference between what the Bible says and how people interpret the Bible.
There are those that would say that the message in the Bible is rather the opposite. You could read the message in Bible to be that there are no grounds to divide people into groups and assign them different value.
“There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.”
