I have arrived @ the point where my faith does not include any sort of determinism. I'm borderline Indeterminate right now. It's a place of great uncertainty and trepidition, but strangely exciting.
No determinism, curing yourself of that poison of the mind, means no "God's Will", no "Karma" and no "Sin". Therefore, I do not believe in original sin.
Original Sin is a notion based on the esoteric economy of souls that Kaballah implies and that Catholicism inherited, and is reflected in the monistic (monetary) economy we operate within today. Money is debt, and debts under the strict "moral order" of Abrahamic religion must always be paid or, it is presumed, there is some great cosmic imbalance that results.
But Original Sin is inherited debt from previous generations, and so, each generation inherits the sin-debt of the previous one in an endless cycle which (it is thought) ensures the divine mandate or necessity for Work (Labour) and thus also the preservation of the Master-Slave dynamic. It's all in the Old Testament, and that's the book of the physical world, the Law.
What it means is that we never own ourselves, "God" does ultimately, and the Master we serve (the System) can buy and sell us on God's behalf @ will by divine mandate.
Under the esoteric system that informs the world systems, that body you are in right now is rented, not owned by you, as a vehicle for your soul. This is affirmed by even a cursory investigation of the legalities of the Birth Certificate, wherein the identity associated with that body is shown to be a Corporate entity, effectively a Strawman, a fiction. The real "you" is endless-nameless, you see...unless you reclaim your sovreignty and choose a name to be know by.
What it all adds up to, is that Original Sin is a legal conceit worked into the System to establish and mandate the necessity for you to Work for and Serve the system itself.
It's a nightmare.
Reject all sin-debt notions, it's the only way to be free.
