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?
No, no, a thousand times no. Neither is there any sin in the apparently disorienting workings of quantum mechanics; extremely small objects simply exhibit wave-like behavior owing to the nature of the cosmos, which is known only to God. As for the rest of us, and in particular regard to those who attempt what one might jokingly call “Quantum theology,” I think I shall quote Richard Feynman, who said on numerous occasions and only partially in jest “If you
think you understand quantum mechanics, you
don’t understand quantum mechanics.”
That's Valentinian Gnosticism.
Valentinianism - Wikipedia
-CryptoLutheran
More than just that of Valentinus,* all forms of Gnosticism from the heresy of Simon Magus straight through to the Manichaeans, Cathars, Bogomils, and Paulicians, and indeed among the Mandaeans of today, are dualistic and feature the idea that matter is evil and only spirit is good, and in these religions, salvation generally consists of shedding matter in order to ascend to a pure spiritual realm.
This idea is of course contrary to all canonical sacred scripture, including the New Testament, even after Marcion attempted to edit it, he could not prove the Gnostic thesis, which is why the Gnostics wound up writing their own fabulous stories.
*What differentiates Valentinus from most is that his religion featured unusual doctrinal sophistication and specifically, explicitly Valentinian texts like “The Gospel of Truth” (a spectacular dual misnomer, for it is neither true nor a Gospel) have come down to us, which we can attribute to his cult with a certainty that exceeds, for example, the probability with which we can attribute some other works to the Tatianists, the Manichees, and other Gnostic sects. Indeed the only cases where we really have a clearer and better preservation of doctrine are in the case of the Paulicians, who converted to Orthodox Christianity in the 19th century leaving behind in fragments a polemical treatise called The Key of Truth, and the Mandaeans, who of course are still alive, but reject our Lord as a false Messiah and profess ostensibly to follow “the exact teachings” of John the Baptist, and to be the descendants of his disciples, which seems unlikely given by their own admission the Mandaeans are and always have been Mesopotamian.
