Claim. UC’s tradition of transracial marriage — willingness to marry “a black person, white person, or yellow person” on True Parents’ recommendation — operationalizes the brotherhood-of-humankind realm that has nothing to do with the Fall, and must be deliberately established now for descendants to inherit.

Elaboration. Moon makes the transracial-marriage tradition explicit: “Since we have transcended the world, white people and black people should be brothers and sisters. This is to realize the brotherhood realm of humankind, the realm of Adam and Eve, which has nothing to do with the Fall… For us, marriage transcends nations. We have the mind-set that we can marry a black person if told to do so, marry a white person if recommended to do so, and marry a yellow person if recommended to do so. Such a tradition should be established from now” (6.6. We must inherit the tradition, 71-19, 1974.3.24).

The framing has three theological functions. (1) Soteriological: transracial marriage is the visible negation of Fall-divided humanity; it instantiates the unified pre-Fall Adamic family at the level of actual family formation. (2) Providential: it must be deliberately established “from now” because no inherited tradition supplies it — Moon must invent it and have it propagated. (3) Ecclesiological: it distinguishes UC from every other religious tradition that operates within ethnic/national boundaries.

The willingness is conditional on True Parents’ recommendation, not personally chosen. The submission is to the matching authority, not to a market-style preference. This is consistent with UC’s distinctive matching practice — couples introduced (often across continents) at large mass weddings, with the matching done by Moon or designated authorities. The transracial pattern is a feature, not a bug, of the matching system.

The justification given is restorationist: “the realm of Adam and Eve, which has nothing to do with the Fall.” Race itself is post-Fall — not in the sense that race is sinful, but in the sense that racial separation as a basis for marital exclusion is a consequence of fallen humanity’s division. Removing the racial barrier in marriage choice is the operational removal of one fall-induced division.

Moon connects this to the tradition-inheritance theme: “You should leave your sons and daughters a tradition that teaches them how to live… a great opportunity that comes only once, an opportunity to educate your children saying, ‘We worked amidst this kind of hardship.‘” The current generation’s transracial marriages are not just personal ethics; they are the establishment of inherited norms for descendants. The tradition must be built now, against current resistance, so that descendants inherit it as default rather than burden.

The principle’s grounding: “Everything will work out if we live for the sake of others.” Living-for-others (altruistic ethic) is the metaphysical engine; transracial marriage is one of its visible expressions. The “two must become one” requirement extends beyond the couple-level — race, nation, tribe all become one in the integrated family.
