YOUCAT Question n. 61 - Part I. In what does the equality of all men consist?

(Youcat answer) All men are equal inasmuch as they have the same origin in the one creative love of God. All men have their Savior in Jesus Christ. All men are destined to find their happiness and their eternal blessedness in God.    

A deepening through CCC

(CCC 361) "This law of human solidarity and charity" (Pius XII, Summi Pontificatus, 3), without excluding the rich variety of persons, cultures and peoples, assures us that all men are truly brethren. 361

Reflecting and meditating 

(Youcat comment) Hence all men are brothers and sisters. Christians should practice solidarity not only with other Christians but with everyone and forcefully oppose racist, sexist, and economic divisions in the one human family.    

(CCC Comment)

(CCC 360) Because of its common origin the human race forms a unity; for "from one ancestor [God] made all nations to inhabit the whole earth" (Acts 17:26; cf. Tob 8:6): O wondrous 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 (Pius XII, encyclical, Summi Pontificatus 3; cf. NA 1).
