Thank you for your comment, and @beaglelady thank you for your response.
Clearly this is not a simple topic, and @T_aquaticus refusal to join is a dialogue makes it impossible.
The fact is that I was trying to make a relatively simple point, which is that the spiritual as defined as love, purpose, and meaning is real. He clearly said that the spiritual is real, but then seems to say that since the spiritual is real, then it must be physical (presumably because he is a materialist.)
Now I know of no evidence that the spiritual is also physical, which was not considered "evidence" to him. If one believes that everything that is real is physical, then how can one accept the fact that something is real and not physical. Of course the same thing is true about God.
The question is not, can humans or science measure the things of God, but is all reality physical. It is not an either or question as atheists like to make it. Many things that are real clearly are physical, while others are spiritual and still others are rational or mental.
You raise the question of knowledge or the rational. Is it physical or something else? Although @beaglelady is right to say that the thoughts of humans are not the things of God, many have used the rational as evidence that humans are created in the Image of God.
Now does the fact that machines are able to read our minds in a limited way mean that ideas are physical. No, not any more than the fact that ideas are stored in a physical pages of a book mean that ideas are physical.
Humans can encode experiences into mental code, which you are right can be decoded by certain machines under certain circumstances, but it is highly unlikely that others can invade our minds and read them without our cooperation. The fact is that knowledge is relational which is the way we encode experience, decode experience, and interpret experience. Knowledge is not physical, even though it uses brains, books, and other media, which are physical.
The spiritual is even more purely relational than the rational, and the physical. It is not basically physical, it is relational.
We need to use whatever knowledge we have to understand the universe and understand God. Of course all knowledge is provisional, even theology, but our faith is not in knowledge but in the Reality behind the knowledge. We must go with the best we have, and if we have a problem with some aspect of it, we need to work on it until it is resolved. We need to reconcile philosophy, which is the basis of the biggest problem here, theology and science in order to free our minds of all these serious conflicts..
