Of all the theological authors I've ever read, the one that stands out as being the most insightful to me is Matthieu Ricard. Even if one were to totally disagree with him, he's still going to make them think.
He has a ph.d. in molecular physics, and was working at the Pasteur Institute with his mentor and Nobel Laureate, Francois Jacob. However, in the early 1970's, he gave that all up and went to work for the Dalai Lama, and has been with him ever since. His books "The Monk and the Philosopher" and "The Quantum and the Lotus" (the latter coauthored with Trinh Xuan Thuan) are top shelf all the way, but I do not recommend the first one unless one is already quite familiar with Buddhist dharma because it's very "heady".
Anyhow, I'll just shortly mention one area that relates to the discussion, but I'll do so very briefly whereas, if there's any questions, I can go on from there and be more elaborate.
In "The Quantum and the Lotus", he poses a problem with believing there's a uncaused creator-god that supposedly created our universe/multiverse. One point is that how can some entity actually create without changing itself? For example, before a painter paints, (s)he must decide to do so, gather up the materials, and go through the motion of painting, all of which involves action that intrinsically are change. If there's no change whatsoever, no action can result. Therefore, any creator-god must change at least a bit in order to create.
But then that leads to another problem, and that is that what would make this creator-god change? IOW, at some point the creator-god would have to be swayed by some outside influence(s) whereas he makes a decision. But that becomes a problem if this creator-god actually originally made all that's "outside" in the first place. Einstein focused in on this problem when he stated how can God not know what He created, and how could there be such a thing as "free will" if God literally created ever single thing?
While I'm at it, Einstein's views are very interesting, and he's very much conflicted over how this all can supposedly mesh together because there's some rather serious problems. Maybe we can get into that later, but right now I'd prefer to just stick with Ricard's questions.
