So no, it may not be hard for you and me to understand it, but it is going to be hard to get our brothers and sisters in Christ to understand it. It is going to lead to misunderstandings and miscommunications, and that is why I keep saying that we need to find other, better ways to express ourselves.
That’s why I focus on concepts such as factual accuracy, rigour, quality control, reproducible results, and not making things up. Yes, it may take longer and more effort to spell these things out than simply saying “methodological naturalism,” but it’s clearer and it’s less open to misunderstanding.
I don’t think it has worked that well (you’ve been doing it a long time, and admirably ; - ). Unless someone has actually worked in the sciences, in practical engineering, in the field or in the laboratory, or at least has a decent understanding of how science is really done, harping on measurements does not necessarily communicate any more clearly either.
Somehow it is the conceptualization that is missing, and we obviously have not arrived yet.
