Christian ethics in the context of "Christian pacifism"

Søren Aabye Kierkegaard (/ˈsɒrən ˈkɪərkəɡɑːrd/ SORR-ən KEER-kə-gard, US also /-ɡɔːr/ -⁠gor; Danish: [ˈsɶːɐn ˈɔˀˌpyˀ ˈkʰiɐ̯kəˌkɒːˀ] ; 5 May 1813 – 11 November 1855) was a Danish theologian, philosopher, poet, social critic, and religious author who is widely considered to be the first existentialist philosopher. He wrote critical texts on organized religion, Christianity, morality, ethics, psychology, love, and the philosophy of religion, displaying a fondness for metaphor, irony, and parables. Much of his philosophical work deals with the issues of how one lives as a "single individual", highlighting the importance of authenticity, personal choice and commitment, and the duty to love. Kierkegaard prioritized concrete human reality over abstract thinking.

Kierkegaard's theological work focuses on Socratic Christian ethics, the institution of the Church, the differences among purely objective proofs of Christianity, the infinite qualitative distinction between man and God, and the individual's subjective relationship to the God-Man Jesus Christ, which came through faith. Much of his work deals with Christian love. He was extremely critical of the doctrine and practice of Christianity as a state-controlled religion (Caesaropapism) like the Church of Denmark. His psychological work explored the emotions and feelings of individuals when faced with life choices. Unlike Jean-Paul Sartre and the atheistic existentialism paradigm, Kierkegaard focused on Christian existentialism.

The Pauline epistles, also known as Epistles of Paul or Letters of Paul, are the thirteen books of the New Testament attributed to Paul the Apostle, although the authorship of some is in dispute. Among these epistles are some of the earliest extant Christian documents. They provide an insight into the beliefs and controversies of early Christianity. As part of the canon of the New Testament, they are foundational texts for both Christian theology and ethics.

Most scholars believe that Paul actually wrote seven of the thirteen Pauline epistles (Galatians, Romans, 1 Corinthians, 2 Corinthians, Philemon, Philippians, 1 Thessalonians), while three of the epistles in Paul's name are widely seen as pseudepigraphic (1 Timothy, 2 Timothy, and Titus). Whether Paul wrote the three other epistles in his name (2 Thessalonians, Ephesians and Colossians) is widely debated. These latter six epistles are believed by some scholars to have come from followers writing in his name, using material from Paul's surviving letters and letters written by him that no longer survive. The Epistle to the Hebrews, although it does not bear his name, was traditionally considered Pauline (although Rome questioned its authorship), but from the 16th century onwards opinion steadily moved against Pauline authorship and few scholars now ascribe it to Paul, mostly because it does not read like any of his other epistles in style and content and because the epistle does not indicate that Paul is the author, unlike the others.

In Christianity, sin is an immoral act and transgression of divine law. The doctrine of sin is central to the Christian faith, since its basic message is about redemption in Christ.

Hamartiology, a branch of Christian theology which is the study of sin, describes sin as an act of offence against God by despising his persons and Christian biblical law, and by injuring others. Christian hamartiology is closely related to concepts of natural law, moral theology and Christian ethics.

Christian democracy is an ideology inspired by Christian social teaching to respond to the challenges of contemporary society and politics.

Christian democracy has drawn mainly from Catholic social teaching and neo-scholasticism, as well as the Neo-Calvinist tradition within Christianity; it later gained ground with Lutherans and Pentecostals, among other denominational traditions of Christianity in various parts of the world. During the nineteenth century, its principal concerns were to reconcile Catholicism with democracy, to answer the "social question" surrounding capitalism and the working class, and to resolve the tensions between church and state. In the twentieth century, Christian democrats led postwar Western and Southern Europe in building modern welfare states and constructing the European Union. Furthermore, in the late twentieth and early twenty-first century, Christian democracy has gained support in Eastern Europe among former communist states suffering from corruption and stagnation.

Restorationism, also known as Christian primitivism, is a religious perspective holding that the early beliefs and practices of the followers of Jesus were either lost or adulterated after his death, and therefore required restoration. It is a view that often "seeks to correct faults or deficiencies, in other branches of Christianity, by appealing to the primitive church as normative model".

Efforts to restore an earlier, purer form of Christianity are frequently a response to denominationalism. As Rubel Shelly put it, "the motive behind all restoration movements is to tear down the walls of separation by a return to the practice of the original, essential and universal features of the Christian religion." Different groups have attempted to implement the restorationist vision in various ways; for instance, some have focused on the structure and practice of the church, others on the ethical life of the church, and still others on the direct experience of the Holy Spirit in the life of the believer. The relative importance assigned to the restoration ideal, and the extent to which the full restoration of the early church is believed to have been achieved, also varies among groups.

Paleoconservatism is a political philosophy and a strain of conservatism in the United States stressing American nationalism, Christian ethics, regionalism, traditionalist conservatism, and non-interventionism. Paleoconservatism's concerns overlap with those of the Old Right that opposed the New Deal in the 1930s and 1940s as well as with paleolibertarianism.

The terms neoconservative and paleoconservative were coined by Paul Gottfried in the 1980s, originally relating to the divide in American conservatism over the Vietnam War. Those supporting the war became known as the neoconservatives (interventionists), as they made a decisive split from traditional conservatism (nationalist isolationism), which then became known as paleoconservatism. Paleoconservatives press for restrictions on immigration, a rollback of multicultural programs and large-scale demographic change, the decentralization of federal policy, the restoration of controls upon free trade, a greater emphasis upon economic nationalism, and non-intervention in the politics of foreign nations.

Polygamy is "the practice or custom of having more than one wife or husband at the same time". Polygamy has been practiced by many cultures throughout history.

Although the Old Testament describes numerous examples of polygyny (one male, one wife with multiple concubines) among devotees to God, most Christian groups have historically rejected the practice of polygamy and have upheld monogamy alone as normative. Nevertheless, some Christian groups in different periods have practiced, or currently do practice, polygamy. Some Christians actively debate whether the New Testament or Christian ethics allows or forbids polygamy and there are several Christian views on the Old Covenant.
