The Presbyterian Church (U.S.A.) has approximately 2.5 million members, 11,200 congregations and 21,000 ordained ministers. Presbyterians trace their history to the 16th century and the Protestant Reformation. Our heritage, and much of what we believe, began with the French lawyer John Calvin (1509-1564), whose writings crystallized much of the Reformed thinking that came before him.

Some of the principles articulated by John Calvin remain at the core of Presbyterian beliefs. Among these are the sovereignty of God, the authority of the scripture, justification by grace through faith and the priesthood of all believers. What they mean is that God is the supreme authority throughout the universe. Our knowledge of God and God's purpose for humanity comes from the Bible, particularly what is revealed in the New Testament through the life of Jesus Christ. Our salvation (justification) through Jesus is God's generous gift to us and not the result of our own accomplishments. It is everyone's job - ministers and lay people alike - to share this Good News with the whole world. That is also why the Presbyterian church is governed at all levels by a combination of clergy and laity, men and women alike.

Presbuteros, the Greek word meaning elder, is used 72 times in the New Testament. It provided the name for the Presbyterian family of churches, which includes the Reformed churches of the world. Both Presbyterian and Reformed are synonymous with churches of the Calvinist tradition. In America, the first presbytery was organized in 1706, the first synod in 1717; the first General Assembly was held in 1789. Today’s Presbyterian Church (U.S.A.) was created by the 1983 reunion of the two main branches of Presbyterians in America, separated since the Civil War: the Presbyterian Church in the U.S. and the United Presbyterian Church in the U.S.A. The latter had been created by the union of the Presbyterian Church in the U.S.A. and the United Presbyterian Church of North America in 1958. The Presbyterian Church (U.S.A.) is distinctly a confessional and a connectional church, distinguished by the representation of elders-laymen and laywomen-in its government.

Our style for doing mission is biblically based and historically appropriate. It builds solidly on our past commitments and mission experience, but it also adapts to newly emerging needs and to changing relationships in a sensitive manner. Mission in the United States is decentralized as much as possible, determined by and administered at the appropriate level of the 16 regional synods, the 173 presbyteries, and the more than 11,000 congregations. Beyond our borders, we engage in mission and relations in partnership with churches and ecumenical bodies in more than 80 countries and territories in Latin American and the Caribbean, Africa, Europe, the Middle East, South Asia, East Asia, and the Pacific. Our witness, corporately and individually, is rooted in the gospel ministries of preaching, teaching, healing, and in Christ’s example of advocacy for the poor, the hungry, and the oppressed.

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. A host of other dedicated workers includes: mission specialists and contract associates; Presbyterian Church members working for overseas employers, recognized as having strategic roles with missionary intent; binational servants, who advocate the insights of one culture while living in another; overseas Christians enabled by Presbyterian Church (U.S.A.) funds and ecumenical planning to go in mission with congregations and presbyteries in the United States.
