Claim. The Proclamation of the Liberation of Hell and Opening of the Gates of Heaven extends the Blessing to Christianity and to spirits in the spirit-world so that those who could not serve True Parents on earth could descend to receive Blessing.
Elaboration. “Whereas Heung-jin is a child of direct descent from the True Parents, Christianity stands in the position of the adopted child from another lineage. Only when these two are united can the True Parents stand up completely straight on a firm foundation” (2.5. Proclamation of the liberation). The spirit-world reach is concrete: “For those spirits that could not live with and serve the True Parents on earth, the Blessing is a ceremony that opens the path for them to come down to earth to serve True Parents.” Order matters: “The order of the providence is such that the spirit world must be set right before the physical world. This is because the spirit world stands perpendicular to the physical world.” The implication: in SMM’s frame, soteriology is bidirectional and posthumous — the dead are not stranded by their earthly era’s lack of True Parents contact; the Blessing reaches them, and the spirit world must be rectified before earthly transformation completes.
