I still don't know why the author brought religion/faith/god into the discussion; he seems like a religionist trying to come to grips with the dominance of our world by science and the scientific epistemology.
Beeeecause this was a lecture delivered at a Catholic philosophy/theology conference?

That's because he is. Take a look at the articles listed on his website.

Science can't tell us so far what really exists. It can only predict experiments. To put it in more common terms, "is the wave function real or not?", or "do quantum fields really exist, or are just elegant mathematical abstractions for explaining experiments?"
Or as others say "shut up and calculate".
> It can only predict experiments.
Your "only" here makes it seem like predicting experiments is a narrow thing. It's not. All of the modern technologies we have--including the computers we're all using to post here--are based on science "predicting experiments"--but the "experiments" are things like building computers, or the Internet, or the GPS system. The fact that all those things work exactly as our science predicts makes it very hard to view that science as "only predicting experiments". It's telling us how to use real things to build real technologies that have real impacts on people's lives.
> Microphysics is the branch of physics that studies molecules, atoms, and elementary particles.
So not quite chemistry, but particle physics?
I don't think it's that narrow. The article mentions the kinetic theory of gases, which explains the observed properties of gases in terms of statistics of the motions of the atoms or molecules that make up the gas. Chemistry also explains observed properties of chemical elements and compounds based on the properties of atoms and molecules. I think those are included in "microphysics" as the article is using the term.
The article does focus on particle physics, I think because that's the most fundamental level of physics we have--everything else is built on it.
