Catholic social teaching in the context of "Christian democracy"

Solidarity or solidarism is an awareness of shared interests, objectives, standards, and sympathies creating a psychological sense of unity of groups or classes. True solidarity means moving beyond individual identities and single issue politics. Still, solidarity does not reject individuals and sees individuals as the basis of society. It refers to the ties in a society that bind people together as one. The term is generally employed in sociology and the other social sciences, as well as in philosophy and bioethics. It is a significant concept in Catholic social teaching and in Christian democratic political ideology. Although closely related to the concept of charity, solidarity aspires to change whole systems, not merely to help individuals.

Solidarity is also one of six principles of the Charter of Fundamental Rights of the European Union, and International Human Solidarity Day is recognized each year on December 20 as an international observance. Solidarity is not mentioned in the European Convention on Human Rights nor in the United Nations' Universal Declaration of Human Rights and therefore has lesser legal meaning when compared to basic rights.

The Catholic Church operates numerous charitable organizations.

Catholic spiritual teaching includes spreading the Gospel, while Catholic social teaching emphasises support for the sick, the poor and the afflicted through the corporal and spiritual works of mercy. The Catholic Church is the largest non-governmental provider of education and medical services in the world.

Traditionalism (Spanish: tradicionalismo) is a Spanish political doctrine formulated in the early 19th century and developed until today. It understands politics as implementing Catholic social teaching and the social kingship of Jesus Christ, with Catholicism as the state religion and Catholic religious criteria regulating public morality and every legal aspect of Spain. In practical terms it advocates a loosely organized monarchy combined with strong royal powers, with some checks and balances provided by organicist representation, and with society structured on a corporative basis. Traditionalism rejects democracy, human rights, constitution, universal suffrage, sovereignty of the people, division of powers, religious liberty, freedom of speech, equality of individuals, and parliamentarism. The doctrine was adopted as the theoretical platform of the Carlist socio-political movement, though it appeared also in a non-Carlist incarnation. Traditionalism has never exercised major influence among the Spanish governmental strata, yet periodically it was capable of mass mobilization and at times partially filtered into the ruling practice.

The Fatherland Front (Austrian German: Vaterländische Front, VF) was the right-wing conservative, authoritarian, nationalist, corporatist, and Catholic ruling political organisation of the Federal State of Austria. It claimed to be a nonpartisan movement, and aimed to unite all the people of Austria, overcoming political and social divisions. Established on 20 May 1933 by Christian Social Chancellor Engelbert Dollfuss as the only legally permitted party in the country, it was aligned with the Catholic Church, and did not advocate any racial ideology. It advocated Austrian nationalism and independence from Germany on the basis of protecting Austria's Catholic religious identity from what they considered a Protestant-dominated German state.

The Fatherland Front, which was strongly linked with Austria's Catholic clergy, absorbed Dollfuss's Christian Social Party, the agrarian Landbund and the right-wing paramilitary Heimwehren, all of which were opposed to Nazism, Marxism, laissez-faire capitalism and liberal democracy. It established an authoritarian and corporatist regime, the Federal State of Austria, which is commonly known in German as the Ständestaat ("corporate state"). According to the Fatherland Front this form of government and society implemented the social teaching of Pope Pius XI's 1931 encyclical Quadragesimo anno. The Front banned and persecuted all its political opponents, including Communists, Social Democrats—who fought against it in a brief civil war in February 1934—as well as the Austrian Nazis who wanted Austria to join Germany. Chancellor Dollfuss was assassinated by the Nazis in July 1934. He was succeeded as leader of the VF and Chancellor of Austria by Kurt Schuschnigg, who ruled until the invigorated Nazis forced him to resign on 11 March 1938. Austria was annexed by Nazi Germany the next day.

Catholic moral theology is a major category of doctrine in the Catholic Church, equivalent to a religious ethics. Moral theology encompasses Catholic social teaching, Catholic medical ethics, sexual ethics, and various doctrines on individual moral virtue and moral theory. It can be distinguished as dealing with "how one is to act", in contrast to dogmatic theology which proposes "what one is to believe".

In politics, integralism, integrationism or integrism (French: intégrisme) is an interpretation of Catholic social teaching that argues the principle that the Catholic faith should be the basis of public law and public policy within civil society, wherever the preponderance of Catholics within that society makes this possible. Integralism is anti-pluralist, seeking the Catholic faith to be dominant in civil and religious matters. Integralists uphold the 1864 definition of Pope Pius IX in Quanta cura that the religious neutrality of the civil power cannot be embraced as an ideal situation and the doctrine of Leo XIII in Immortale Dei on the religious obligations of states. In December 1965, the Second Vatican Council approved and Pope Paul VI promulgated the document Dignitatis humanae—the council's "Declaration on Religious Freedom"—which states that it "leaves untouched traditional Catholic doctrine on the moral duty of men and societies toward the true religion and toward the one Church of Christ". However, they have simultaneously declared "that the human person has a right to religious freedom," a move that some traditionalist Catholics such as Archbishop Marcel Lefebvre, the founder of the Society of St. Pius X, argue is at odds with previous doctrinal pronouncements.

The term is sometimes used more loosely and in non-Catholic contexts to refer to a set of theoretical concepts and practical policies that advocate a fully integrated social and political order based on a comprehensive doctrine of human nature. In this generic sense some forms of integralism are focused purely on achieving political and social integration, others national or ethnic unity, while others were more focused on achieving religious and cultural uniformity. Integralism has, thus, also been used to describe non-Catholic religious movements, such as Protestant fundamentalism or Islamism. In the political and social history of the 19th and 20th centuries, the term integralism was often applied to traditionalist conservatism and similar political movements on the right wing of a political spectrum, but it was also adopted by various centrist movements as a tool of political, national and cultural integration.
