God created everything “in its whole substance” from nothing (ex nihilo) in the beginning.
(Lateran IV; Vatican Council I)
Genesis does not contain purified myths. (Pontifical Biblical Commission 1909)
Genesis contains real history—it gives an account of things that really happened. (Pius XII)
Adam and Eve were real human beings—the first parents of all mankind. (Pius XII)
Polygenism (many “first parents”) contradicts Scripture and Tradition and is condemned. (Pius XII; 1994 Catechism, 360, footnote 226: Tobit 8:6—the “one ancestor” referred to in this Catechism could only be Adam.)
The “beginning” of the world included the creation of all things, the creation of Adam and Eve and the Fall (Jesus Christ [Mark 10:6]; Pope Innocent III; Blessed Pope Pius IX, Ineffabilis Deus).
The body of Eve was specially created from a portion of Adam’s body (Leo XIII). She could not have originated via evolution.
Various senses are employed in the Bible, but the literal obvious sense must be believed unless reason dictates or necessity requires (Leo XIII, Providentissimus Deus).
Adam and Eve were created upon an earthly paradise and would not have known death if they had remained obedient (Pius XII).
Evolution must not be taught as fact, but instead the pros and cons of evolution must be taught. (Pius XII, Humani Generis)
