Claim. Sun Myung Moon teaches relentlessly that the chasm between fallen humans and God is fundamentally about the spiritual dimension of human sexuality — the man-woman relationship — and that without resolving this, even “good” people remain caught in the satanic blood lineage (“children of your father the devil,” 44) and cannot access God’s deepest love in eternity.
Elaboration. Hendricks frames this as the distinctive UC reading of the human condition (per Value 2: People Are Spiritually Lost and God Is Suffering). The Divine Principle gives the same diagnosis: “there is one social vice that human efforts alone can never eradicate. That is sexual immorality. Christian doctrine regards this as a cardinal sin. What a tragedy that today’s Christian society cannot block this path of ruin” (EDP, p. 5).
The structural claim: sin is not primarily ethical (which Christians and other faiths can address), nor primarily of the heart (likewise broadly available), but of lineage — passed through physical generation and resolvable only through a sacramental restoration of lineage. This is why the Blessing is the load-bearing UC sacrament: it is the rite that addresses the diagnosis. The atomic messiah-completes-physical-marriage-and-family-salvation explains why the messianic mission must therefore include physical/familial completion.
For Hendricks this is the radical message that should drive UC evangelism — what makes UC distinct from other faiths that excel at ethics and heart.
