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 this, and
audaciously support the monistic and pantheistic opinion that the world is in continual evolution. Communists gladly subscribed to this opinion so that, when the souls of men have been deprived of every idea of a personal God, they may the more efficaciously defend and propagate their dialectical materialism.
However, although We know that Catholic teachers generally avoid these errors, it is apparent, however, that some today, as in apostolic times, desirous of novelty, and
fearing to be considered ignorant of recent scientific findings try to withdraw themselves** from the sacred Teaching Authority** and are accordingly in danger of gradually departing from revealed truth and ***of drawing others along with them into error. ***
- Unfortunately these advocates of novelty easily pass from despising scholastic theology to the neglect of and even contempt for the Teaching Authority of the Church itself, which gives such authoritative approval to scholastic theology. This Teaching Authority is represented by them as a hindrance to progress and an obstacle in the way of science.
Nor must it be thought that what is expounded in Encyclical Letters does not of itself demand consent, since in writing such Letters the Popes do not exercise the supreme power of their Teaching Authority. …But if the Supreme Pontiffs in their official documents purposely pass judgment on a matter up to that time under dispute, it is obvious that that matter, according to the mind and will of the same Pontiffs,
cannot be any longer considered a question open to discussion among theologians.
