Normally I would recommend learning how to program and then trying to get a job that is related to your field. Both of those don’t apply to you. You know how to program but your knowledge is not up to date and your field of study makes it hard for you to find a programming job where knowledge of theology would be a benefit. I don’t know of any type of programming job where you can leverage your subject expertise in theology. Maybe you have some other expertise you gained by working that can be leveraged?

Anyway. You still can look into the jobs available to you locally and find out what technologies are being used and concentrate your study on those fields. Also see what meetups you have going on and participate.

Other then that I think with your knowledge you might be better off going for a project manager position in tech.
