Claim. The conclusion of the providence of restoration is the sequential recovery of three rights — eldest son, parent, kingship — that Adam forfeited at the fall; only after all three are restored does the realm of the royal family emerge.
Elaboration. SMM gives the sequence: “The final comprehensive conclusion of the providence of restoration is the restoration of the right of the eldest son, the restoration of the right of the parent, the restoration of the right of kingship, and the restoration of the right of the royal family. The purpose of the restoration of the right of the eldest son is the restoration of the right of the parent, the purpose of the restoration of the right of the parent is the restoration of the right of kingship, and the purpose of the restoration of the right of kingship is the restoration of the right of the royal family” (3.2. The Three Great Kingships, 249-306 1993.10.11). And the order is causal, not merely sequential: “Without the restoration of the right of the eldest son, there can be no restoration of the parents. Since the original brother and sister were lost, we can only be elevated to the position of the parents on the foundation of having found the original brother and sister once again” (246-146 1993.4.7). The doctrine grounds the Cain/Abel pattern and the True Parents axis in a single recovery chain: brothers → parents → king → royal family.
