I’m not apologetic about the term and the distinction between it and philosophical naturalism. It’s not that hard to understand.
If God is the artist in nature, because we can analyze the resultant brushstrokes and their sequential development scientifically does not mean God is removed from the picture. (The paintbrush is in another realm that we are not privy to because we have no divinometer™.)
Methodological naturalism is the analysis of the paint and the brush strokes. Philosophical naturalism is the denial that there is an Artist.
