. . "Summi Pontificatus sees Christianity being universalized and opposed to racial hostility and superiority. There are no racial differences, because the human race forms a unity, because \"one ancestor [Adam] made all nations to inhabit the whole earth\". \n* What a wonderful vision, which makes us contemplate the human race in the unity of its origin in God. . . in the unity of its nature, composed equally in all men of a material body and a spiritual soul; in the unity of its immediate end and its mission in the world; in the unity of its dwelling, the earth, whose benefits all men, by right of nature, may use to sustain and develop life; in the unity of its supernatural end: God himself, to whom all ought to tend; in the unity of the means for attaining this end;. . . in the unity of the redemption wrought by Christ for all. This divine law of solidarity and charity assures that all men are truly brethren, without excluding the rich variety of persons, cultures and societies."@en . . . . .
