Who is who

Baptists (58)

Percentage of American population : 17%

It is the largest Protestant denomination in the United States today. The first Baptist church dates back to 1609. It was founded in Holland by an English pastor who separated from the Anglican Church. As heirs to the Anabaptists and the English Separatist Puritans, Baptists baptize adults by immersion, hence their name. Some of the denominations recognize the ministry of women, and the first Baptist woman was ordained as a pastor in the United States in 1815.

Catholics (59)

Percentage of American population : 24%

At the beginning, Catholicism was restricted in the United States. While Maryland had been as a haven for Catholic migrants in the 17th century, it was when California and Florida joined the Union that it expanded, and continued to do so with the great waves of Italian and Irish migration in the 19th century. The American Catholic Church has long been suspected of being under foreign influence.

Congregationalists (60)

Percentage of American population : less than 1%

Congregationalists appeared during the English Reformation in the sixteenth century. They advocated complete autonomy of parishes, without a central ecclesiastical authority, which differentiated them from the Presbyterians who were also “reformed” and therefore closer to Calvin’s views. They also differ from Anglicanism, which they want to “purify” from overly Catholic influences and compromission with the state, which is why they were nicknamed “Puritans”. They are the ones who sailed on the Mayflower in 1620.

Episcopalians (61)

Percentage of American population : 2%

Anglicanism was in American colonies as early as 1607, before becoming the Episcopalian Church after the Revolution, in 1789, because Anglicanism was deemed too closely connected to the English. Episcopalians, like all Anglicans, have no confession of faith and follow the great conciliar texts of early Christianity. Today, they are noted for their liberalism and their commitment to minority rights.

Lutherans (62)

Percentage of American population: 4%

Lutheran immigrants from Scandinavia and Germany settled the first communities in the 17th and 18th centuries. Today, Lutherans in America are divided between three major churches that agree on the fundamentals of Luther’s doctrine (by Scripture, by grace and by faith alone), but differ on issues such as the authority and the reading of the Bible, and on ethical issues (homosexuality, abortion, women’s ordination, etc.).

Mennonites (63)

Percentage of American population : less than 1%

Taking their name from Menno Simons (1496-1561), founder of a strictly nonviolent branch of Anabaptism in the Netherlands, Mennonites were persecuted in Europe throughout the 17th century. Quaker leader William Penn offered them shelter in Pennsylvania, where they settled in 1683. They refused military service and, for some, technological progress, as did the Amish. The latter followed the teachings of a Swiss Mennonite dissident, Jakob Amman (1645-1730).

Methodists (64)

Percentage of American population: 5%

The term “Methodist” was originally pejorative and referred to the “methodical” piety of its followers. In the 18th century, John Wesley launched a movement within the Church of England that focused on Bible study, individual conversion, and community enthusiasm to shake up the apathy of the official church. Thanks to the success of his method, he was able to pursue his movement in America around 1770. Methodists are greatly diverse in terms of theology and ethical issues today.

Others (65)

Percentage of American population: 13%

This category includes Protestants who do not identify with any specific tradition mentioned here. They also include Mormons, millenarian churches such as the Adventists who await Christ’s return to earth, or “restorationists” who want to restore Christianity’s original purity. Some of these beliefs may be shared by some of the traditions listed here.

Pentecostals (66)

Percentage of American population: 5%

African-American pastor William Joseph Seymour (1870-2011) founded the Pentecostal movement in 1906 in Los Angeles. By 2020, it had become the world’s fastest growing religious denomination. Pentecostals focus on life-transformation through faith and baptism with the Holy Spirit, an experience that can be conveyed through speaking in tongues, a reference to the biblical episode of Pentecost. The Bible holds definitive authority in matters of faith.
Famous American Pentecostal: Jerry Lee Lewis

Presbyterians (67)

Percentage of American population: 3%

The first Presbyterians came from England and Scotland, and had Reformer John Knox their founder. They had close ties with the Reformed Churches in continental Europe, and they value education and mission. Internal divisions over the question of slavery marked the 19th century. In the 20th century, Presbyterians are mostly progressive on issues such as the environment, sexual morality, ecumenism and business ethics.

Quakers (68)

Percentage of American population: less than 1%

In 1652, English dissident George Fox founded the Religious Society of Friends. His followers are known as Quakers (“tremblers”), a nickname inflicted by their detractors who mocked their legendary agitation during prayer. Their presence in the United States could be traced as early as 1656. Lay people are very active, including women from the 17th century onwards. Quakers were very involved in the abolitionist struggle of the 19th century. Their meeting for worship services are mostly spent in quiet, silent prayer.
Famous American Quaker: Joan Baez

Reformed (69)

Percentage of American population : less than 1%

These churches, which originated in 17th-century Dutch immigration, were part of the Calvinist Reformation movement, whose strict observance they advocated. They professed the infallibility and literal inspiration of the Bible and advocated rigorous marital morality. One of these churches supports Calvin College and Calvin Seminary, which are renowned places of higher and theological education in Grand Rapids, Michigan.
