Faith in the one God, Creator and Redeemer of all humankind made in his image and likeness, constitutes the absolute and inescapable negation of any racist ideologies. It is still necessary to draw out all the consequences of this: "We cannot truly pray to God the Father of all if we treat any people in other than brotherly fashion, for all men are created in God's image."
The Church and Racism: Towards a More Fraternal Society, Pontifical Commission on Justice and Peace, 1988, #19.
The equality of men rests essentially on their dignity as persons and the rights that flow from it: Every form of social or cultural discrimination in fundamental personal rights on the grounds of sex, race, color, social conditions, language, or religion must be curbed and eradicated as incompatible with God's design.
Catechism of the Catholic Church, The Vatican, 1992, #1935.
