Constantinianism is a religiopolitical ideology in Christian politics that epitomizes the unity of church and state, as opposed to separation of church and state. This view is modeled after an ideal Christendom, which arose during the reign of Constantine the Great.
Contemporary theologians have used the term to characterize a view that Christians should readily participate in liberal democracies.
Fundamentally, the Constantinian view deeply identifies the Church and state, taking inspiration from the Roman Empire following the Edict of Milan. [1] Some elements of this identification are willingness by the church to use coercive power structures of the state and a tendency towards Christian triumphalism. [2]
Stanley Hauerwas argues against a Constantinian view, saying that it leads to a compromised form of Christian ethics, "[It] leads Christians to judge their ethical positions, not on the basis of what is faithful to our particular tradition, but rather on the basis of how much Christian ethics Caesar can be induced to swallow." [3]
John Howard Yoder and Karl Barth have been identified as an anti-Constantinian due to their shared "church-world" distinction. [4]
Christendom historically refers to the Christian states, Christian empires, Christian-majority countries and the countries in which Christianity dominates, prevails, or that it is culturally or historically intertwined with.
The emerging church, sometimes wrongly equated with the "emergent movement" or "emergent conversation", is a Christian movement of the late 20th and early 21st century. Emerging churches can be found around the globe, predominantly in North America, Western Europe, Australia, New Zealand, and Africa. Members come from a number of Christian traditions. Some attend local independent churches or house churches while others worship in traditional Christian denominations. The emerging church favors the use of simple story and narrative. Members of the movement often place a high value on good works or social activism, including missional living. Proponents of the movement believe it transcends labels such as "conservative" and "liberal"; it is sometimes called a "conversation" to emphasize its developing and decentralized nature, its range of standpoints, and commitment to dialogue. Participants seek to live their faith in what they believe to be a "postmodern" society. Disillusionment with the organized and institutional church has led participants to support the deconstruction of modern Christian worship and evangelism, and the nature of modern Christian community.
Systematic theology, or systematics, is a discipline of Christian theology that formulates an orderly, rational, and coherent account of the doctrines of the Christian faith. It addresses issues such as what the Bible teaches about certain topics or what is true about God and His universe. It also builds on biblical disciplines, church history, as well as biblical and historical theology. Systematic theology shares its systematic tasks with other disciplines such as constructive theology, dogmatics, ethics, apologetics, and philosophy of religion.
Constantinian shift is used by some theologians and historians of antiquity to describe the political and theological changes that took place during the 4th-century under the leadership of Emperor Constantine the Great. Rodney Clapp claims that the shift or change started in the year 200. The term was popularized by the Mennonite theologian John H. Yoder. He claims that the change was not just freedom from persecution but an alliance between the State and the Church that led to a kind of Caesaropapism. The claim that there ever was a Constantinian shift has been disputed; Peter Leithart argues that there was a "brief, ambiguous 'Constantinian moment' in the fourth century", but that there was "no permanent, epochal 'Constantinian shift'".

Sacralism is the confluence of church and state wherein one is called upon to change the other. It also denotes a perspective that views church and state as tied together instead of separate entities so that people within a geographical and political region are considered members of the dominant ecclesiastical institution.
During the reign of the Roman Emperor Constantine the Great, Christianity began to transition to the dominant religion of the Roman Empire. Historians remain uncertain about Constantine's reasons for favoring Christianity, and theologians and historians have often argued about which form of early Christianity he subscribed to. There is no consensus among scholars as to whether he adopted his mother Helena's Christianity in his youth, or, as claimed by Eusebius of Caesarea, encouraged her to convert to the faith he had adopted.
Christian ethics, also known as moral theology, is a multi-faceted ethical system. It is a virtue ethic, which focuses on building moral character, and a deontological ethic which emphasizes duty. It also incorporates natural law ethics, which is built on the belief that it is the very nature of humans – created in the image of God and capable of morality, cooperation, rationality, discernment and so on – that informs how life should be lived, and that awareness of sin does not require special revelation. Other aspects of Christian ethics, represented by movements such as the social Gospel and liberation theology, may be combined into a fourth area sometimes called prophetic ethics.

Christians have had diverse attitudes towards violence and nonviolence over time. Both currently and historically, there have been four attitudes towards violence and war and four resulting practices of them within Christianity: non-resistance, Christian pacifism, just war, and preventive war. In the Roman Empire, the early church adopted a nonviolent stance when it came to war because the imitation of Jesus's sacrificial life was preferable to it. The concept of "Just War", the belief that limited uses of war were acceptable, originated in the writings of earlier non-Christian Roman and Greek thinkers such as Cicero and Plato. Later, this theory was adopted by Christian thinkers such as St Augustine, who like other Christians, borrowed much of the just war concept from Roman law and the works of Roman writers like Cicero. Even though "Just War" concept was widely accepted early on, warfare was not regarded as a virtuous activity and expressing concern for the salvation of those who killed enemies in battle, regardless of the cause for which they fought, was common. Concepts such as "Holy war", whereby fighting itself might be considered a penitential and spiritually meritorious act, did not emerge before the 11th century.

Neo-Anabaptism is a Christian theological movement in the late twentieth and early twenty-first century inspired by classical Anabaptism. According to Stuart Murray, neo-Anabaptists "identify with the Anabaptist tradition and are happy to be known as Anabaptists, but have no historic or cultural links with any Anabaptist-related denomination".
