The Presbyterian Church (USA), often abbreviated as PC(USA), is a mainline Protestant denomination in the United States. It was formed in 1983 through the merger of the United Presbyterian Church in the USA and the Presbyterian Church in the United States. The church follows a Reformed tradition and emphasizes the sovereignty of God, the authority of Scripture, and the necessity of grace through faith. Governance in the PC(USA) is characterized by a system of representative democracy, where decisions are made by elected elders and ministers. The church is organized into local congregations, regional bodies called presbyteries, and larger governing bodies known as synods and the General Assembly. The PC(USA) is known for its commitment to social justice and inclusivity.
