There is a scene in the movie Moneyball where Billie Bean says:
“What I want to know is: do they get on base?”
Similarly, what I want to know about a given theology is: does it work?
That is, theology must be seen as secondary.
What matters is practical applications – what are their results?
It’s similar to scientific theories. If they didn’t work – if they didn’t have practical consequences in terms of developing useful technologies – no one would care about science. Furthermore, one of the ways we test a theory – perhaps one of the most important ways – is to integrate it into various technologies.
In a sense, then, proper theology should be far more robustly based on evidence than science itself.
With theology, “How do I test this?” should be one of the first questions one asks.
