Claim. The Blessing is the providential mechanism by which fallen humanity’s lineage is engrafted back into God’s original lineage — the “absolute lineal conversion” that no individual effort can accomplish alone.
Elaboration. §2.3.3 names the Blessing as the unique lineage-transfer mechanism. “Since lineal identity is necessary, humankind cannot help but follow God’s realm of heart. That is not possible if the root and the trunk are different. However, the buds must come from the same root and trunk. The incredible matter of the absolute lineal conversion takes place there. That cannot be accomplished through one’s own efforts alone – there first must be True Parents” (2.3.3. Lineage is restored through the Blessing, 172-55, 1988.1.7). The engrafting language is reinforced: “Despite your diverse lineages and backgrounds, in order for you to resemble the True Parents, the great feat of engrafting must take place. You must all writhe and squirm to be engrafted. You yourselves must pay off your remaining debts of indemnity” (ibid, 24-203, 1969.8.10). The implication is that the Blessing reframes salvation away from individual forensic forgiveness (the standard evangelical account) and toward a literal change-of-root that requires True Parents as the new origin.
