This is not a criticism of an outstanding pope, Pius XII, but of the advanced understanding of Teilhard of our place in Nature

1940 – Teilhard de Chardin, The Phenomenon of Man p. 219

“Is evolution a theory, a system or a hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforth if they are to be thinkable and true.”

1950 -  Pope Pius XII, The encyclical Humani Generis


“Some imprudently and indiscreetly hold that evolution, which has not been fully proved even in the domain of natural sciences, explains the origin of all things, and audaciously support the monistic and pantheistic opinion that the world is in continual evolution.”

1996 - Pope John Paul II to the Pontifical Academy of Science

“Today, almost half a century after the publication of the encyclical, (Humani Generis) new knowledge has led to the recognition of the theory of evolution as more than a hypothesis. It is indeed remarkable that this theory has been progressively accepted by researchers, following a series of discoveries in various fields of knowledge." The convergence in the results of these independent studies—which was neither planned nor sought—constitutes in itself a significant argument in favor of the theory.
