10 From what We have said so far, it is easy to conclude, Venerable Brothers, how far removed from procuring a secure peace are those who trample under foot the sacred rights of the Catholic Church. They forbid her ministers the free exercise of religious worship. They even condemn them to exile and to prison. They impede or directly proscribe and destroy schools and institutes of education which are conducted according to Christian norms and principles. Through errors, calumnies and every kind of indecency, they draw the people, especially the tender youth, away from integrity of morals, from virtue and innocence, to the allurements of vice and corruption.
