Pius XII’s Humani Generis says the following:
*4. Furthermore the human intelligence sometimes experiences difficulties in forming a judgment about the credibility of the Catholic faith, notwithstanding the many wonderful external signs God has given, which are sufficient to prove with certitude by the natural light of **reason alone *the divine origin of the Christian religion.
And now from the Dogmatic Constitution on the Catholic Faith:
4. Nevertheless, in order that the submission of our faith should be in accordance with reason, it was God’s will that there should be linked to the internal assistance of the Holy Spirit external indications of his revelation, that is to say divine acts, and first and foremost miracles and prophecies, which clearly demonstrating as they do the omnipotence and infinite knowledge of God, are the most certain signs of revelation and are suited to the understanding of all.
Later on it says:
6. Now, although the assent of faith is by no means a blind movement of the mind, yet* no one can accept the gospel **preaching in the way that is necessary for achieving salvation without the inspiration and illumination of the Holy Spirit, who gives to all facility in accepting and believing the truth *
How isn’t this contradictory? It seems like this is saying we need the inspiration of the Holy Spirit to be able to have faith, but then also reason alone can bring you to know the Catholic faith is true, so that in the end it’s the Holy Spirit that gives a person recognition that the external signs are proof of Catholicism’s truth. But then it’s not from reason alone that we can recognize these signs, as Pius XII says in his Encyclical, but rather from the Holy Spirit who gives us the faith to be able to how these signs make it credible.
Can someone help me out with this?
