...Was the first sin, then, simple disobedience? That doesn’t really seem likely. Obedience, like anything else, must be learned.
Rather, I think the first sin was humanity not trusting in God but trying to guard themselves by hiding from him; humans covering themselves up both physically and metaphorically - with fig leaves and with the sloughing off of blame onto others - rather than revealing themselves and taking responsibility for their actions.
The taint of Original Sin: God has been trying to get us to trust Him, to reveal ourselves to Him and to be vulnerable (open) to Him ever since.Perhaps this explains the command by God for the Jews to circumcise the men. The foreskin of the penis affords some protection for the organ - a bit of shelter, a place to hide. When God chose the Jews as His own, he required this symbolic (and real) acquiescence - this willingness to be completely vulnerable and exposed to whatever may come. The unsheathed penis is extraordinarily sensitive and responsive - precisely the qualities God wanted of the Jews.

The need to be vulnerable and open to God is part and parcel of having a real relationship with Him, just as it is the necessary component in human relationships. We see the blood covenant and the need for vulnerability and openness mirrored in the relationship between a husband and wife - or we did, when virginity was kept for marriage.

In remaining a virgin until marriage, the woman becomes vulnerable only (but fully) to her husband, and he - in receiving that vulnerability - answers only to her, gives his deepest self and the sweat of all of his labors to her. It is another blood covenant. At the shedding of that blood, they become one flesh. One entity....
