In examining a possible truth. You first need to proper tool to do the exploring. Is it science a proper tool. A lot think that it is. However it's actually not.
Science is experiment and observation based. So in order to confirm a truth scientifically you need to go "there" to do experiments and observations. Thus science is only efficient in exploring 'things' inside our physical realm or time-space. Spiritual claims are about what lying outside our physical realm which is unreachable by our science (under the assumption that a truth could possibly be there). To put it another way, even when a truth lies there there is no way that you can approach such a truth as we can't go there to do experiments or observations to confirm it scientifically. This is the limitation of our science.
I do agree that science is not the proper tool for such an exploration, but while searching for truth in scripture science is invaluable as a constraint as to what the stories can or cannot possibly be actually about.
I disagree that the truth of any given spiritual claim cannot be observed, confirmed or refuted according to the scientific method.
The way I see it, if scripture clearly says that in the very day a person eats pork they will surely die and anyone can see that is not even remotely true then either the story is about something else out it is complete nonsense.
When searching for deeper meaning only alluded to by the words used the mind is the only tool capable of such an inquiry.
That is why a modern person must have a sober knowledge of reality and scientific discoveries about the nature of the laws that govern the material universe to even have a chance to comprehend what bronze age people were secretly teaching their children about the harsh realities of the world in which they lived..
A second grade education about how to look for the moral of a fairy tale would be helpful, understanding metaphors, allegories, homonyms, hyperbole, etc.
One way to test if the laws of God are in effect, as Jesus claimed, one just has to find a person who violates the law to see if they have died in any way as a consequence of that forbidden behavior.
I propose that if a person does not have the conscious awareness about how ridiculous and degrading it is to seek help or spiritual life of any kind from something that has no life of any kind, as with those who worship, pray to, and eat the eucharist for spiritual life, they evidently have already received "the death" consequent and are already under the condemnation of God.
