Claim. A loyal subject earns love from his own clan, but the saintly version requires being loved by the world — which is achievable only by loving the unrelated and the foreign.
Elaboration. SMM frames filial piety not just as inward duty but as outward earnable affection that must extend beyond kinship: “You must earn the love of all three generations: grandparents, parents, uncles and aunts, and grandchildren. They all have to like you. You cannot become a filial child if even just one of these people is unhappy about you” (CSG 14.3 §2, 298-278, 1999.1.16). At higher scope: “Anyone can love their own race. Everyone can love their own countries, but you have to love people from other countries, too. This is because God does not only love Korea” (CSG 14.4 §1, 155-235, 1965.10.31). The saint’s ratification therefore requires demonstrable love that crosses what would otherwise be the natural circles of preference.
