Etsi Multa
If you have not read this encyclical against the horrors of kulturkampf, take time to read it now, please.
This is what we are facing now.
A section.
Harassing of the Church
20. What We have recounted so far is common knowledge. Monks and virgins devoted to God are deprived of the common liberty of ordinary citizens and ejected with enormous cruelty, Catholic schools are daily being taken away from the care of the Church, and sodalities for pious works and even seminaries are dissolved. Additionally, the liberty of evangelical preaching is interfered with, hindered, teaching religion in the native language is forbidden in certain parts of the kingdom. Curates are withdrawn from their parishes, and prelates themselves are deprived of revenues coerced in many ways, and frightened with threat of imprisonment. While Catholics are vexed with all kinds of harassment such as these, how can We possibly acquiesce to what is suggested and not invoke the religion of Jesus Christ and the truth?
Government Support for Heretics
21. Nor is this the limit of the injuries which are committed against the Catholic Church. In addition the Prussian and other governments of the German Empire openly support those recent heretics who call themselves Old Catholics. Their abuse of such a name would be plainly ridiculous if it were not for the fact that so many monstrous errors of this sect against the principal teachings of the Catholic faith, so many sacrileges in divine service and the administration of the sacraments, so many grave scandals, and so much ruin of souls redeemed by the blood of Christ did not force tears from Our eyes.
Further Heresies
22. And surely what these sons of perdition intend is quite clear from their other writings, especially that impious and most imprudent one which has only recently been published by the person whom they recently constituted as a pseudo-bishop. For these writings attack and pervert the true power of jurisdiction of the Roman Pontiff and the bishops, who are the successors of blessed Peter and the apostles; they transfer it instead to the people, or, as they say, to the community. They obstinately reject and oppose the infallible magisterium both of the Roman Pontiff and of the whole Church in teaching matters. Incredibly, they boldly affirm that the Roman Pontiff and all the bishops, the priests and the people conjoined with him in the unity of faith and communion fell into heresy when they approved and professed the definitions of the Ecumenical Vatican Council. Therefore they deny also the indefectibility of the Church and blasphemously declare that it has perished throughout the world and that its visible Head and the bishops have erred. They assert the necessity of restoring a legitimate episcopacy in the person of their pseudo-bishop, who has entered not by the gate but from elsewhere like a thief or robber and calls the damnation of Christ upon his head.
