Presbyterian history is part of the history of Christianity, but the beginning of Presbyterianism as a distinct movement occurred during the 16th-century Protestant Reformation. As the Catholic Church resisted the reformers, several different theological movements splintered from the Church and bore different denominations. Presbyterianism was especially influenced by the French theologian John Calvin, who is credited with the development of Reformed theology, and the work of John Knox, a Scotsman who studied with Calvin in Geneva, Switzerland and brought his teachings back to Scotland. The Presbyterian church traces its ancestry back primarily to England and Scotland. In August 1560 the Parliament of Scotland adopted the Scots Confession as the creed of the Scottish Kingdom. In December 1560, the First Book of Discipline was published, outlining important doctrinal issues but also establishing regulations for church government, including the creation of ten ecclesiastical districts with appointed superintendents which later became known as presbyteries.
