We have a soul and body today, but were we just a soul beforehand?
Mind–body dualism sounds like wave-particle duality to me. Would that mean we were quantum waves before sin?
Does sin have something to do with physical objects?
we are a soul . We have a spirit , which lives in our body like a temporary rental home for our spirit which is the life. A living soul is when a living spirit unites with a body that exists in this physical realm.
man has always been two parts it’s evident from the creation
“And the Lord God
formed man of the dust of the ground,
and breathed into his nostrils
the breath of life; and man became a living soul.”
Genesis 2:7
I think your asking about this part
“And the Lord said,
My spirit shall not always strive with man, for that
he also is flesh: yet his days shall be an hundred and twenty years.”
Genesis 6:3 KJV
if I understand your asking was man spirit and flesh before sin ?
flesh is created of material , but a body has no animation no life just like the dust . Mankind is a spirit which came from God , places inside the vehicle of the body. Those two elements make a living soul.
man “ became “ a living soul when Gods spirit of life was placed into the created body. The duality of our nature came from the consumption of the knowledge of good and evil. That’s what creates the war of spirit and flesh the knowledge of good and evil.
in the beginning when God made mankind , first he seperated the dark from the light , the light he called good . This shows us that there was good and evil in the beginning before mankind was created but God seperated good and evil and then he made man in his image
This image was of the light , all that was good , already being seperate from evil . The reason God forbid the knowledge of good and evil is because he had already created man good having seperate good and evil beforehand and then commanded them not to partake of the good and evil knowledge .
when they partook thier eyes were opened to the option of doing evil as well as good which was not Gods will that man struggle between good and evil it was satans plan that they become conflicted between good and evil.
the duel nature of man began as soon as they are the fruit , defiling the warning God gave them for their protection and following a lie meant to cause them to be at war within thier own self between serving good or evil.
man is not designed by God to have a conflicted nature as we do now , that’s the very reason he forbid the fruit mans designed to have a nature like Jesus , we’re designed to be reflections of Gods morality and thoughts. God doesn’t strugggle with temptation , we do , because of the duality of good and evil inside of one “ kingdom “ the heart of mankind
notice as your talking about duality the New Testament doctrine is about dying to the flesh and living to the spirit. Putting to death the evil and living by the good
