Man and Sin by Piet Schoonenberg (1964) 2.3 BI

Summary of text [comment] page 81

Schoonenberg noted that Paul wrote, “We know that the law is spiritual, but I am carnal, sold under sin.”

He contrasted the I that agrees with the law with the I that is sold to sin.

Even though both ‘I’s refer to the same person, Paul rejects the latter as not I but the sin that dwells in me (Romans 7:20).

[This logic underlies the portrayal, in An Archaeology of the Fall, of the Genesis serpent acting as the projection of Eve’s own unconscious thoughts.]
