Claim. The “physical fall” was Eve seducing Adam into a premature conjugal sexual relationship — before either had reached the maturity at which God-sanctioned union was meant to occur. Adam thereby inherited the Lucifer-elements Eve had received in the spiritual fall, and these have been transmitted through lineage ever since.
Elaboration. Per 1.3.2. The Crime of the Human Beings: Adam and Eve covered their lower parts after the fall (not their hands or mouths), indicating that their sexual organs were “the instruments of their sinful deed.” 33 corroborates (“If I have concealed my transgressions like Adam, by hiding my iniquity in my bosom”). The only act one would commit at the clear risk of death is the act of love.
Per 2.2.2. The Physical Fall: post-spiritual-fall, Eve “stood in the position of the Archangel with respect to Adam” — she seduced him as Lucifer had seduced her, hoping that union with her intended spouse would dispel her guilt-dread and restore her to God. Adam responded, formed common base, and “the power of the unprincipled love… induced Adam to abandon his original position and brought them together in an illicit physical relationship of sexual love.”
A counterfactual is critical: “What if Adam had reached perfection without having yielded to fallen Eve’s temptation? The providence to restore Eve would have been relatively easy.” But Adam fell too — and humanity has multiplied in sin from that lineage ever since.
