Claim. Unfallen Adam and Eve were to be “God in bodily form” — God’s external face on earth, the first ancestors of humankind and simultaneously the visible incarnation of the invisible Creator.
Elaboration. The strongest formulation in the section: “Adam and Eve are the first ancestors of humankind, [but] they were also supposed to be God, who rules over heaven and earth. Adam and Eve were to be God in bodily form” (2.2.-adam-is-the-first-ancestor-and-visible-god, 133-91, 1984.7.10). And: “Eve was Adam’s wife, a wife with physical form. If Adam were God incarnate, Eve would be God’s wife incarnate” (ibid, 22-279, 1969.5.4).
This is the structural premise behind the True Parents claim: because the Fall prevented Adam and Eve from achieving this incarnation, the messianic mission is to bring a new couple to the position God originally intended (true-parents, messiah-completes-physical-marriage-and-family-salvation).
Importantly, “God incarnate” here is not the Christological hypostatic union — it is union by love, after maturity, with Adam and Eve as distinct persons whose minds are filled by God. The internal/external Father language (“God is the internal Father, and Adam the external father”) preserves the distinction even at its tightest.
