I had a free night recently and watched this 1950 film, Guilty of Treason it is about the persecution and trial of Cardinal Mindzenty, it reflects its culture and its time but it contains the central message that no political regime can tolerate. 'Mindzenty must be destroyed', is the central message of the film.
Earlier I had read an article about a new document by the International Theological Commission, entitled "The Triune God, Unity of People. Christian Monotheism Against Violence ", which was commissioned by Pope Benedict, which identifies modern cultures as polytheistic: if there are many gods then there are many truths. Monotheism says there is one Truth, polytheism can happily exist with multiple or even conflicting truths. Hence modern western culture is pro-gods but ultimately anti-God and desires the destruction of God.
I am afraid my source is Eponymous Flower, the translation is a bit painful but I am grateful they make an attempt. It is significant that the document speaks not only about why the Church is persecuted today but also how. If you watch the film you will see that almost 65 years on things haven't changed, either the reasons for persecution or the methods. Magister also has short piece on the same document.
In Mindzenty's case persecution was because of his stance on the education of children and involved first the destruction of his reputation, then the destruction of him as person.
It is a sad reflection on the Church's history that in the 1950s/60s Mindzenty became an embarrassment to the Holy See and was as much a thorn in Cardinal Casaroli's side as he was for the Communist regime.
József Mindszenty (29 March 1892 – 6 May 1975) was the Prince Primate, Archbishop of Esztergom, cardinal, and leader of the Catholic Church in Hungary from 2 October 1945 to 18 December 1973. For five decades, he personified uncompromising opposition to fascism and communism in Hungary in support of religious freedom. During World War II, he was imprisoned by the pro-Nazi authorities. After the war, he opposed communism and the communist persecution in his country. As a result, he was tortured and given a life sentence in a 1949 show trial that generated worldwide condemnation, including a United Nations resolution. After eight years in prison, he was freed in the Hungarian Revolution of 1956 and granted political asylum by the United States embassy in Budapest, where Mindszenty lived for the next fifteen years. He was finally allowed to leave the country in 1971. He died in exile in 1975 in Vienna, Austria.
