PCUSA
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.

Christian worship joyfully ascribes all praise and honor, glory and power to the triune God. In worship the people of God acknowledge God present in the world and in their lives. As they respond to God’s claim and redemptive action in Jesus Christ, believers are transformed and renewed. In worship the faithful offer themselves to God and are equipped for God’s service in the world.
