First Presbyterian Church is part of the Christian denomination known as The Presbyterian Church (USA). The denomination has approximately 2.3 million members, more than 10,000 congregation, and 14,000 ordained and active clergy. The denominations offices are located in Louisville, Kentucky.

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 the wave of 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. As far back as 1837, the General Assembly declared that the church, by its very nature, is a missionary society whose purpose is to share the love of God in Jesus Christ in word and deed and with all the world. Witnessing to the good news of Jesus Christ throughout the world, Presbyterians engage in mission activities, seek to alleviate hunger, foster self-development, respond to disasters, support mission works, preach the gospel, heal the sick, and educate new generations for the future. In partnership with more than 150 churches and Christian organizations around the world, the missionary efforts of the Presbyterian Church (U.S.A.) involve approximately 1,000 volunteers and compensated personnel.
