Claim. A couple united in true-love on earth becomes mutually internal in the spirit-world — each spouse visibly carries the other inside, resembling God’s united dual-characteristics.
Elaboration. SMM describes the phenomenon literally: “In the spirit world, when a couple is truly one in spirit and body, at any time the man can become the woman, and the woman can become the man … If you look inside a woman, there will be a man within her. Her husband will be within her” (1.4. The lives and relationships of people in spirit world, 205-97, 1990.7.7). The basis is theological — couples return to the unified-dual structure of God: “It is exactly the same with God’s dual characteristics. Since men and women have been separated from God’s internal nature and external form, when they return to the origin, they need to climb the ladder of love” (ibid). The earthly evidence test is visible: “When you go to the spirit world and look at a man who lived happily with his wife on earth, you will find a woman inside him … She will be that man’s beloved wife. That is the greatest ideal” (ibid, 226-141, 1992.2.2). The implication is that the blessing-grounded marital union is what makes a spirit person God-like, not merely virtuous.
