The authority of the sovereign state lies solely in its indispensable role in promoting the general welfare of all persons, as Genesis I, and the Christian apostolic mission define all persons, as made equally in the image of the Creator of the Universe, and thus equally subjects of the obligation to promote the welfare of both the living and their posterity.
Only sovereign government has the means to promote the conditions of the general welfare respecting all of the people and all of the land-area, both for the living and future generations, and that thus, the existence of such sovereign nation-state republics is shown to be the morally required condition of mankind.
