Claim. Satan is not a metaphor or a principle but a real being — the archangel who fell through fornication with Eve, becoming the adulterer of God’s love and the false father of humanity through stolen lineage.
Elaboration. §1.3 identifies Satan ontologically and historically. “What kind of a being is Satan actually? … He is an adulterer, an adulterer of love. That being, Satan, beat the father to death and violated the mother. You are the children born as a result” (1.3. The devil Satan fell through fornication, 38-175, 1971.1.3). The premise that this rules out forgiveness of Satan: “Even though God has taught us to love our enemies, He has not asked us to love Satan, the adulterer. Satan cannot be forgiven. You can love those who belong to Satan, but cannot forgive Satan himself” (ibid, 148-294, 1986.10.25). The implication is that the doctrine of restoration cannot be reduced to the spread of grace or moral exhortation — it requires the literal change of the polluted lineage of Satan back to the original lineage of God, because lineage is what was actually stolen at the Fall.
