Thirteenth Lecture
"From what has been said, it is not difficult to see what is to be thought of the principle of the ‘absolute freedom of science’. This principle grants every individual the right to form and advocate any opinion they choose, without fear of any doctrinal authority objecting to it. But freedom is not boundless. The Church's teaching authority has the right to condemn a philosophical opinion if it contradicts a revealed teaching or logically leads to such a contradiction. We assume here that an ecclesiastical teaching authority has been established by God with the task of protecting and interpreting divine revelation. With this mandate, the right in question is directly established. For the execution of the mandate given to it, the teaching office of the Church must be able to explain the true meaning of the word of God and to designate false interpretations as false. Hence, when the opinion of a philosopher or of a school of philosophy directly or indirectly challenges the true meaning of the content of revelation, the teaching authority of the Church has the power to judge the error as such and the authority to condemn it before the public.
