The Presbyterian Church of Australia is a part of the Christian Church throughout the world. The Church's name comes from the Greek word presbuteros, which is the word for an elder or a mature Christian leader in the New Testament. The use of the name Presbyterian reflects the Church's aim to be faithful to the Bible's teaching on the Church, even in the 21st Century. In its wider use, the name Presbyterian has also come to include the distinctive doctrine, discipline, worship, laws and practice of the churches which returned to Biblical standards in Europe at the time known as the Reformation.
