Catholic Church in the 20th century

The Roman Catholic Church in the 20th century entered into a period of renewal, responding to the challenge of increasing secularization of Western society and persecution resulting from great social unrest and revolutions in several countries.

It advocates for fair labor conditions, living wages, and the right to form trade unions, establishing a framework that balances the rejection of socialism with a critique of unchecked capitalism.

Subsequent teachings, like Quadragesimo anno and the works of Pius XII, expand these principles, emphasizing solidarity, subsidiarity, and the moral dimensions of economic life.

This body of teaching continues to evolve, addressing modern social, economic, and technological issues while advocating for justice and the dignity of all individuals.

Released on 15 May 1931, this encyclical expanded on Rerum novarum, noting the positive effect of the earlier document but pointing out that the world had changed significantly since Pope Leo's time.

Unlike Leo, who addressed mainly the condition of workers, Pius XI concentrated on the ethical implications of the social and economic order.

Prior to Quadragesimo anno, some Catholics had wondered whether Leo XIII's condemnation of radical left-wing politics in Rerum novarum extended only to outright communism or whether it included milder forms of socialism as well.

[34] After World War II historians such as David Kertzer accused the Church of encouraging centuries of anti-Semitism, and Pope Pius XII of not doing enough to stop Nazi atrocities.

[70] Regarding the matter, historian Derek Holmes wrote, "There is no doubt that the Catholic districts, resisted the lure of National Socialism Nazism far better than the Protestant ones.

[80] South America, historically Catholic, has experienced a large Evangelical and Pentecostal infusion in the 20th century due to the influx of Christian missionaries from abroad.

In addition, the encyclical reaffirmed the sanctity of life from conception to natural death and asserted a continued condemnation of both abortion and euthanasia as grave sins which were equivalent to murder.

[105][106][107] The sexual revolution of the 1960s precipitated Pope Paul VI's 1968 encyclical Humanae vitae (On Human Life), which rejected the use of contraception, including sterilization, claiming these work against the intimate relationship and moral order of husband and wife by directly opposing God's will.

[109] This encyclical condemned the "culture of death" which the pope often used to describe the societal embrace of contraception, abortion, euthanasia, suicide, capital punishment, and genocide.
