4 Our country has seen and suffered great evils in such a short span of time, for the faith of our fathers has been made a sign for persecutions of every sort. The satanic intent of the persecutors has been to substitute naturalism for Christianity, the worship of reason for the worship of faith, so-called independent morality for Catholic morality, and material progress for spiritual progress. To the holy maxims and laws of the Gospel, they have opposed laws and maxims which can be called the code of revolution. They have also opposed an atheistic doctrine and a vile realism to school, science, and the Christian arts. Having invaded the temple of the Lord, they have squandered the booty of the Church's goods, the greatest part of the inheritance necessary for the ministers, and reduced the number of priests by the conscription of clerics beyond the limits of extreme need. If the administration of the sacraments could not be impeded, they sought nonetheless to introduce and promote civil marriages and funerals. If they have not yet succeeded in seizing control of education and the direction of charitable institutions, they always aim with perseverance to laicize everything, which is to remove the mark of Christianity from it. If they could not silence the voice of the Catholic press, they made every effort to discredit and revile it.
