Claim. Pledge 2’s claim that “our family represents and becomes central to heaven and earth” means that each Blessed family stands in the same representative position as the unfallen Adam-Eve family — not as one family among five billion.
Elaboration. SMM treats the language as load-bearing, not rhetorical: “What is pledge number two? ‘Our family… pledges to represent and become central to heaven and earth by attending God and True Parents…’ … Adam and Eve were to be the central family and the representative family in heaven and on earth. There is only one representative family. The center is one. That is the seed. Adam and Eve were to be the seed of the blessed, married families. All the seeds of that family are equal. Your families should be the same” (2.1. Our family pledges to represent and become central to heaven and earth, 263-60 1994.8.16). He elaborates the seed-claim: “You should not think that your Blessed Family is just one family among the five billion people of the human race. The opposite is the case. Your family represents all five billion of humankind” (267-148 1995.1.4). Pledge 2 thus relocates the Blessed family from “exemplary minority” to “axis of all families”.
