Christianity in the United States in the context of "Christianity by country"

Islam is the third-largest religion in the United States (1.34%) after Christianity (67%) and Judaism (2.4%). The 2020 United States Religion Census estimates that there are about 4,453,908 Muslim Americans of all ages living in the United States in 2020, making up 1.34% of the total U.S. population. In 2017, twenty states, mostly in the South and Midwest, reported Islam to be the largest non-Christian religion.

The first Muslims to arrive in America were enslaved people from West Africa (such as Omar ibn Said and Ayuba Suleiman Diallo). During the Atlantic slave trade, an estimated 10 to 30 percent of the slaves brought to colonial America from Africa were Muslims, however Islam was suppressed on plantations and the majority were forced to convert to Christianity. Nearly all enslaved Muslims and their descendants converted to Christianity during the 18th and 19th centuries, though the Black power movement of the 20th century would later influence the revival of Islam among descendants of slaves. Prior to the late 19th century, the vast majority of documented Muslims in North America were merchants, travelers, and sailors.

Disputes regarding the internal consistency and textual integrity of the Bible have a long history.

Classic texts that discuss questions of inconsistency from a critical secular perspective include the Tractatus Theologico-Politicus by Baruch Spinoza, the Dictionnaire philosophique of Voltaire, the Encyclopédie of Denis Diderot and The Age of Reason by Thomas Paine.

Protestantism is the largest grouping of Christians in the United States, with its combined denominations collectively comprising about 43% of the country's population (or 141 million people) in 2019. Other estimates suggest that 48.5% of the U.S. population (or 157 million people) is Protestant. Simultaneously, this corresponds to around 20% of the world's total Protestant population. The U.S. contains the largest Protestant population of any country in the world. Baptists comprise about one-third of American Protestants. The Southern Baptist Convention is the largest single Protestant denomination in the U.S., comprising one-tenth of American Protestants. Twelve of the original Thirteen Colonies were Protestant, with only Maryland having a sizable Catholic population due to Lord Baltimore's religious tolerance.

The country's history is often traced back to the Pilgrim Fathers whose Brownist beliefs motivated their move from England to the New World. These English Dissenters, who also happened to be Puritans—and therefore Calvinists—, were first to settle in what was to become the Plymouth Colony. America's Calvinist heritage is often underlined by various experts, researchers and authors, prompting some to declare that the United States was "founded on Calvinism", while also underlining its exceptional foundation as a Protestant majority nation. American Protestantism has been diverse from the very beginning with large numbers of early immigrants being Anglican, various Reformed, Lutheran, and Anabaptist. In the next centuries, it diversified even more with the Great Awakenings throughout the country.

Dominion theology, also known as dominionism, is a group of Christian political ideologies that seek to institute a nation governed by Christians based on their understandings of biblical law. Prominent adherents of those ideologies include Calvinist Christian reconstructionism, Charismatic and Pentecostal Kingdom Now theology, and the New Apostolic Reformation. Extents of rule and ways of acquiring governing authority are varied. For example, dominion theology can include theonomy but does not necessarily involve advocacy of adherence to the Mosaic Law as the basis of government. The label is primarily applied to groups of Christians in the United States.

Most of the contemporary movements that are labeled dominion theology arose in the 1970s from religious movements asserting aspects of Christian nationalism. Roman Catholic integralism is also sometimes considered to fall under the dominionist umbrella, but the Catholic integralist movement is much older and theologically markedly different from Protestant dominionism since it is tied to the doctrine that the Catholic Church is the only true church.

The Seven Mountain Mandate, also Seven Mountains Mandate, 7M, 7MM, or Seven Mountains Dominionism, is a dominionist conservative Christian ideology within evangelical Christianity, particularly independent Charismatic groups. It holds that there are seven aspects of society that believers seek to dominate: family, religion, education, media, arts and entertainment, business, and government.

It originated from a perceived divine message to evangelicals Loren Cunningham, Bill Bright, and Francis Schaeffer to influence seven key areas of society. Initially, Cunningham framed these spheres as a framework for evangelism rather than cultural takeover. Over time, particularly after the 2000 meeting between Cunningham and Lance Wallnau and the 2013 publication of Invading Babylon: The 7 Mountain Mandate by Wallnau and Bill Johnson, the movement adopted a more dominion-oriented focus, encouraging strategic social and political influence. It has been linked to the New Apostolic Reformation and gained visibility through figures like Paula White and support for Donald Trump, with a 2024 poll indicating that 41% of American Christians believe in 7MM.

The Southern Baptist Convention (SBC), alternatively the Great Commission Baptists (GCB), is a Christian denomination based in the United States. It is the world's largest Baptist organization, the largest Protestant, and the second-largest Christian body in the United States. The SBC is a cooperation of fully autonomous, independent churches with commonly held essential beliefs that pool some resources for missions.

Churches affiliated with the denomination are evangelical in doctrine and practice, emphasizing the significance of the individual conversion experience. This conversion is then affirmed by the person being completely immersed in water for a believer's baptism. Baptism is believed to be separate from salvation and is a public and symbolic expression of faith, burial of previous life, and resurrection to new life; it is not a requirement for salvation. The denomination has a male pastorate, often citing 1 Timothy 2:12 as the reason it does not ordain women. All affiliated churches deny the legitimacy of same-sex marriage, saying that marriage can only be between a man and a woman, and also that all sexual relations should occur only within the confines of marriage. Other specific beliefs based on biblical interpretation vary by congregational polity, often to balance local church autonomy.

The National Council of the Churches of Christ in the USA, usually identified as the National Council of Churches (NCC), is the largest ecumenical body in the United States. NCC is an ecumenical partnership of 38 Christian faith groups in the United States. Its member communions include mainline Protestant, Eastern Orthodox, Oriental Orthodox, African-American, evangelical, and historic peace churches. Together, it encompasses more than 100,000 local congregations and 40 million adherents. It began as the Federal Council of Churches in 1908, and expanded through merger with several other ecumenical organizations to become the National Council of Churches in 1950. Its Interim President and General Secretary is Bishop Vashti Murphy McKenzie.
