Circular logic is technically valid, but it doesn't get you anywhere.
I'm not using circular logic, you are. I'm using a simple "IF-THEN" statement to make a point... IF you don't believe in spirituality, THEN you will not accept spiritual evidence. There is nothing circular about that logic, it is just plain old regular normal logic.
Circular logic is when you say that you don't believe in god because there is no physical evidence of god.
IF there was physical evidence of god, it would no longer be spiritual.
yes and no, boss.
with proving how spiritual healing works to cure patients of cancer, schizophrenia, etc.
there is both spiritual process going on that we cannot fully SEE
and also medical and physical changes that we can measure and document
as following specific patterns before and after the therapy that heals such conditions.
so it can be shown to work medically using scientific measure and methods
and it still can be a spiritual process
it is possible for people to see this works
and still see it as natural and nothing to do with God
so the point is not so much to prove it has to be from a God
but to prove that the processes are universal
so we can still agree on and apply those regardless of our beliefs of where it comes from
I have a friend who went through the same spiritual healing process
as in Scott Peck's book where he treated two schizophrenic patients suffering
from demonic voices that were removed or controllable after he conducted
spiritual deliverance as the priests do by their traditions
Peck noted that one of the patients did not convert or become religious after she was cured
but went the other way and gave up her new age religion and went into science instead
my friend also received the healing from demonic rage and voices he previously
was not able to control but got back control of his mind after the same deliverance
process, and he also is not Christian but remains nontheist. the prayers and healing
still work. he accepted to receive the prayers for forgiveness for generational abuse from the past,
and that is what broke through the self-destructive addictions and demonic voices, regardless what level these are on, real or not,
scientifics or spiritual or whatever. Before these demonic obsessions were there, and he suffered mentally and physically;
and afterwards he could keep them out of his mind where he went back to normal.
so we can show this same process works, even for nontheists who remain nontheist like my friend.
we can show it is universal, whether one person sees the science or the other the spiritual process.
you don't personally have to believe it comes from "God" yourself as your own way of looking at it,
to "believe" the fact that these are the same laws or process that Chrisitans refer
to when THEY talk about God and authority of Jesus to remove demonic influences.
You don't have to believe the same thing they do, to see it is what THEY mean by THEIR beliefs.
we can still prove this process works scientifically
it does not change the fact that hte spiritual part of the process remains faith-based
and you can look at it either way and understand other people see it another way.
it's still the same process and it's universal for all humanity.
