Presbyterian is a person who follows the religion called Presbyterianism. Presbyterianism refers to many different Christian churches adhering to the Calvinist theological tradition within Protestantism, and organized according to a characteristic Presbyterian polity. Presbyterian theology typically emphasizes the sovereignty of God, the authority of the Scriptures, and the necessity of grace through faith in Christ. Presbyterianism originated primarily in Scotland and was confirmed as the means of Church Government in Scotland by the Acts of Union in 1707. Most Presbyterians found in England can trace a Scottish connection and the denomination was taken to North America by Scots and Scots-Irish immigrants.
The earliest Christian church consisted of Jews in the first century who had known Jesus Christ and heard his teachings. It gradually grew and spread from the Middle East to other parts of the world, though not without controversy and hardship among its supporters.
During the 4th century, after more than 300 years of repression and sometimes fierce persecution under various Roman emperors, the church became established as a political as well as a spiritual power under the Emperor Constantine. Theological and political disagreements, however, served to widen the rift between members of the eastern (Greek-speaking) and western (Latin-speaking) branches of the church. Eventually the western portions of Europe came under the religious and political authority of the Roman Catholic Church. Eastern Europe and parts of Asia came under the authority of the Eastern Orthodox Church.
