These enemies of divine revelation extol human progress to the skies, and with rash and sacrilegious daring would have it introduced into the Catholic religion as if this religion were not the work of God but of man, or some kind of philosophical discovery susceptible of perfection by human efforts.
Pope Pius IXIt is error to believe that Every man is free to embrace and profess that religion which, guided by the light of reason, he shall consider true.
Pope Pius IXBecause God knows, searches and clearly understands the minds, hearts, thoughts, and nature of all, his supreme kindness and clemency do not permit anyone at all who is not guilty of deliberate sin to suffer eternal punishments.
Pope Pius IXThe foundation of all our confidence is found in the Blessed Virgin Mary. God has committed to her the treasury of all good things, in order that everyone may know that through her are obtained every hope, every grace, and all salvation. For this is His will: That we obtain everything through Mary.
Pope Pius IX
