If I'm being charitable, he's ignorant and not exactly college professor level material - the point of college level discourse is the diversity of ideas and discussion. A professor that doesn't want you to write an interpretation of themes and ideas needs to specify that in the rubric. Otherwise the default assumption is that they're asking you to think on it and produce a unique take.

You probably won't get anywhere in a religious school though. You just kinda need to ask yourself if the juice is worth the squeeze. If you feel you can talk to him, pop in during his office hours and talk about how others see these same things, see what his take is.
