Claim. Only when Cain and Abel unite is the foundation-of-substance formed — and only then can the Messiah come and restore the lineage. The unresolved Cain-Abel relation is the structural blockage of providential history.
Elaboration. SMM names the load-bearing pieces of his doctrinal contribution: “The great contribution I made lies in the fact that I clarified the relationship between God and human beings centered on love, and clarified the portion of responsibility and the course of indemnity, as well as the problem of Cain and Abel, and the issue of the lineage. Unless Cain and Abel unite, the Messiah cannot come. Only when Cain and Abel become one is the foundation of substance formed, and only then can the Messiah come” (2.2. The ultimate issue is the restoration of lineage, 161-149, 1987.1.18). The Adam-loss schema gives the broader sequence: “Adam lost faith and substance, he can only find love after he has restored the foundation of faith and the foundation of substance. So what did Adam lose? First, he lost faith, and then he lost substance, and lastly he lost love” (ibid, 65-314, 1973.3.4). Cain-Abel reconciliation is therefore not a moral exhortation but the necessary substructure on which the Messiah’s lineage-graft becomes possible.
