From the Constitution of the Anglican church of Australia:
The Anglican Church of Australia, being a part of the One holy Catholic and Apostolic Church of Christ, holds the Christian Faith as professed by the Church of Christ from primitive times and in particular as set forth in the creeds known as the Nicene Creed and the Apostles’ Creed.
This Church receives all the canonical scriptures of the Old and New Testaments as being the ultimate rule and standard of faith given by inspiration of God and containing all things necessary for salvation.
This Church will ever obey the commands of Christ, teach his doctrine, administer his sacraments of holy Baptism and holy Communion, follow and uphold his discipline and preserve the three orders of bishops, priests and deacons in the sacred ministry.
This Church, being derived from the Church of England, retains and approves the doctrine and principles of the Church of England embodied in the Book of Common Prayer together with the Form and Manner of Making Ordaining and Consecrating of Bishops, Priests and Deacons and in the Articles of Religion sometimes called the Thirty-nine Articles but has plenary authority at its own discretion to make statements as to the faith ritual ceremonial or discipline of this Church and to order its forms of worship and rules of discipline and to alter or revise such statements, forms and rules, provided that all such statements, forms, rules or alteration or revision thereof are consistent with the Fundamental Declarations contained herein and are made as prescribed by this Constitution. Provided, and it is hereby further declared, that the above-named Book of Common Prayer, together with the Thirty-nine Articles, be regarded as the authorised standard of worship and doctrine in this Church, and no alteration in or permitted variations from the services or Articles therein contained shall contravene any principle of doctrine or worship laid down in such standard.
Provided further that until other order be taken by canon made in accordance with this Constitution, a bishop of a diocese may, at his discretion, permit such deviations from the existing order of service, not contravening any principle of doctrine or worship as aforesaid, as shall be submitted to him by the incumbent and churchwardens of a parish.
Provided also that no such request shall be preferred to the bishop of a diocese until the incumbent and a majority of the parishioners present and voting at a meeting of parishioners, duly convened for the purpose, shall signify assent to such proposed deviations. Such meeting shall be duly convened by writing, placed in a prominent position at each entrance to the church and by announcement at the morning and evening services, or at the service if only one, at least two Sundays before such meeting, stating the time and place of such meeting, and giving full particulars of the nature of the proposed deviation.
Subject to the Fundamental Declarations and the provisions of this chapter this Church has plenary authority and power to make canons, ordinances and rules for the order and good government of the Church, and to administer the affairs thereof. Such authority and power may be exercised by the several synods and tribunals in accordance with the provisions of this Constitution.
This Church will remain and be in communion with the Church of England in England and with churches in communion therewith so long as communion is consistent with the Fundamental Declarations contained in this Constitution.
