Neither science nor reason nor theology are people who can have quarrels.
Here. I made you a 10 cent Venn. If you’re talking about fields of human study, or about methodologies used by humans in argumentation, you can draw Venn diagrams showing overlap of all three with each other and likely there’s areas where all three overlap.
I don’t have to fill them in further.
You’ll find aspects of each that are found in the others and areas that are distinct where you’ll find quarrel even to the point where the other’s point of view is simply absurd to even consider, as it does not fit at all within that particular paradigm.
For example, you’ll find a lot of overlap between reason and theology within the school following Calvinism. They were /are big on reason arguments.
Or if you want overlap between theology and science, you can follow Arminianism lines whose churches tend to be very pro science.
