The Presbyterian Church (U.S.A.), with denominational offices in Louisville, Kentucky, has approximately 2 million members, more than 10,000 congregations and 14,000 ordained and active ministers. Presbyterians trace their history to the 16th century and the Protestant Reformation. Our heritage, and much of what we believe, began with John Calvin (1509-1564), whose writings crystallized much of the Reformed thinking that came before him. Presbyterians are distinctive in two major ways: they adhere to a pattern of religious thought known as Reformed theology and a form of government that stresses the active, representational leadership of both ministers and church members.
