Evolution, Creation, and Laudato Si': Where the Church Actually Stands

It still surprises many Catholics, and more non-Catholics, to learn that the Church has no official quarrel with the theory of evolution as a biological account of how the diversity of life developed. Pius XII’s 1950 encyclical Humani Generis permitted Catholics to hold evolutionary theory as a serious scientific hypothesis regarding the origin of the human body, so long as certain doctrinal lines were not crossed. John Paul II went further in 1996, telling the Pontifical Academy of Sciences that new evidence made evolution “more than a hypothesis” as a description of common descent. Genesis was never intended, on the Church’s own longstanding principles of interpretation, as a scientific treatise competing with biology on its own terms; Augustine himself, sixteen centuries before Darwin, warned against reading the creation accounts with a wooden literalism that would embarrass the faith when better natural knowledge came along.

The doctrinal lines that remain are narrower than either side of the popular debate tends to assume. The human soul, Catholic teaching holds, cannot be the product of a purely material evolutionary process — it is directly created by God in every individual case, since a spiritual, immaterial reality cannot emerge from purely material antecedents by natural causation alone, however sophisticated the biology. And the Church has historically taught monogenism — descent of the entire human race from a single first pair — a position in some tension with the polygenism most population geneticists take as settled, since Catholic teaching on original sin has traditionally been articulated in terms of a single origin and a single fall transmitted to all their descendants. This is a live area of theological work rather than a fully settled question — some theologians argue current formulations of original sin can be restated without strict monogenism, others regard the doctrine as more tightly bound to it than that. It is worth being honest that this is unfinished business, not a solved problem quietly being ignored.

Laudato Si’ (2015) moved the conversation from the origin of the human person to the human person’s ongoing relationship with the created order, and it has taken fire from two directions that reveal the same underlying tension the evolution debate does. Some environmentalist readers have found the encyclical’s continued insistence on human beings as possessing a unique dignity and vocation within creation — rather than simply one species among others with no special claim — too anthropocentric, not willing to go as far as a fully biocentric ecological ethic would ask. Some more traditionally-minded Catholic critics, conversely, have argued the encyclical’s economic and political conclusions — its sharp critique of consumerism, its skepticism toward market-based solutions, its warnings about a “technocratic paradigm” — reach beyond what Scripture and natural law can actually establish, importing contestable secular policy positions under the cover of magisterial authority.

Both criticisms deserve to be taken seriously rather than waved off, and both point to the same real difficulty: applying settled doctrinal principles (creation is good, humanity has real stewardship responsibility, nothing in creation exists solely for exploitation) to contested empirical and economic questions (which specific policies actually serve the poor and the environment simultaneously) inevitably involves prudential judgments that carry less authority than the doctrinal principles feeding into them. The doctrine that creation is a gift entrusted to human stewardship, not a resource with no claims on us at all, is solid ground the encyclical stands on firmly. Exactly which economic arrangements best honour that stewardship is a harder question, on which faithful Catholics, taking the same doctrine seriously, can and do disagree.
