Congregationalism in the context of "Reformed church"

The Pilgrims, also known as the Pilgrim Fathers, were the English settlers who travelled to North America on the ship Mayflower and established the Plymouth Colony at what now is Plymouth, Massachusetts, United States. John Smith had named this territory New Plymouth in 1620, sharing the name of the Pilgrims' final departure port of Plymouth, Devon, England. The Pilgrims' leadership came from religious congregations of Brownists or Separatists who had fled religious persecution in England for the tolerance of 17th-century Holland in the Netherlands.

These Separatists held many of the same Calvinist religious beliefs as Puritans, but unlike Puritans (who wanted a purified established church), Pilgrims believed that their congregations should separate from the Church of England, which led to them being labelled Separatists. After several years of living in exile in Holland, they determined to establish a new settlement in the New World and arranged with investors to fund them. In 1620, they established the Plymouth Colony, in which they erected Congregational churches. The Puritans' later establishment of the Massachusetts Bay Colony eventually became more powerful in the area; but the Pilgrims' story nevertheless became a central theme in the history and culture of the United States.

Reformed Christianity, also called Calvinism, is a major branch of Protestantism that began during the 16th-century Protestant Reformation. In the modern day, it is largely represented by the Continental Reformed, Presbyterian, and Congregational traditions, as well as parts of the Anglican (known as "Episcopal" in some regions), Baptist and Waldensian traditions, in addition to a minority of persons belonging to the Methodist faith (who are known as Calvinistic Methodists).

Reformed theology emphasizes the authority of the Bible and the sovereignty of God, as well as covenant theology, a framework for understanding the Bible based on God's covenants with people. Reformed churches emphasize simplicity in worship. Several forms of ecclesiastical polity are exercised by Reformed churches, including presbyterian, congregational, and some episcopal. Articulated by John Calvin, the Reformed faith holds to a spiritual (pneumatic) presence of Christ in the Lord's Supper.

John Calvin (/ˈkælvɪn/; Middle French: Jehan Cauvin; French: Jean Calvin [ʒɑ̃ kalvɛ̃]; 10 July 1509 – 27 May 1564) was a French theologian, pastor and reformer in Geneva during the Protestant Reformation. He was a principal figure in the development of the system of Christian theology later called Calvinism, including its doctrines of predestination and of God's absolute sovereignty in the salvation of the human soul from death and eternal damnation. Calvinist doctrines were influenced by and elaborated upon Augustinian and other Christian traditions. Various Reformed Church movements, including Continental Reformed, Congregationalism, Presbyterianism, Waldensians, Baptist Reformed, Calvinist Methodism, and Reformed Anglican Churches, which look to Calvin as the chief expositor of their beliefs, have spread throughout the world.

Calvin was a tireless polemicist and apologetic writer who generated much controversy. He also exchanged cordial and supportive letters with many reformers, including Philipp Melanchthon and Heinrich Bullinger. In addition to his seminal Institutes of the Christian Religion, Calvin wrote commentaries on most books of the Bible, confessional documents, and various other theological treatises.
