In 2007, at which time it had over 375,000 members, it assumed "Australian Christian Churches" as its public name, but remained registered as the incorporated Assemblies of God in Australia until 2013.

[1] Its 20 articles are summarized below: At the end of the 20th century, there was a decrease in emphasis on speaking in tongues as the initial evidence as well as the Second Coming of Christ as traditionally understood by Pentecostals.

[2] At the same time, the church growth movement and the prosperity gospel became important parts of the denomination's identity.

"Registered" churches (mature and self-supporting) are autonomous but agree to abide by the United Constitution, state by-laws, and policies of the National Conference, the highest governing body of the Assemblies of God.

Australian Christian Churches supports many organisations including Mercy Ministries, Teen Challenge and Compassion Australia.In order to train future pastors and leaders in the denomination, Commonwealth Bible College (also known as Southern Cross Bible College, and now known as Alphacrucis) was established in 1948 as the official ministry training school of Australian Christian Churches.

At the beginning of the 21st century, it was estimated that there are over 3,000 full-time students being trained at bible colleges affiliated with Australian Christian Churches.

The first steps towards a denominational structure were made in 1927 when the founder of the Good News Hall in Melbourne, Sarah Jane Lancaster, and her network of churches, collaborated with colorful and controversial itinerant evangelist Frederick Van Eyk (sometimes spelled Eyck) of the South African Apostolic Faith Mission (AFM) to form the Australasian AFM.

Doctrinal controversy, disputes over female authority, the volatile character of its leaders and accusations of immorality against Van Eyk led to the movement splitting.

[19] Besides the controversy over Van Eyk, many Queensland pastors had long been concerned over Lancaster's non-Trinitarian and annihilationist beliefs.

He came to Australia in 1930 and stayed two years, beginning an evangelistic work in Brisbane which grew to fill a two thousand seat tent, the Canvas Cathedral.

After a year of revival, Valdez left to pursue itinerant evangelism, and Kelso Glover became the new pastor of Richmond Temple and leader of the PCA.

Glover was baptised in the Holy Spirit at the Azusa Street revival and was one of the rare participants in early American Pentecostalism with an intellectual background.

Glover thought the greatest need of the Pentecostal movement in Australia was "preachers, anointed of God and rightly instructed in the Word".

[24] In April 1928, Donald Gee of the Assemblies of God in Great Britain attended the annual convention of the PCA.

Originating in Great Britain, the Apostolic Church was distinct from the majority of Pentecostal groups at the time by its belief in the fivefold offices of apostle, prophet, evangelist, pastor and teacher.

Most Pentecostals saw prophecy as a function open to the entire Spirit baptised congregation, not as offices given to specific persons.

After this upset, the PCA, along with the Assemblies of God Queensland, struggled to distance itself from the Apostolic Church's teaching.

[26] Led by Enticknap (Queensland), Greenwood (Victoria), and Duncan (New South Wales), the AGQ and PCA held a "United Conference" at the Pentecostal Church in Sydney in 1937.

[28] In 1939, the AOG declared British Israelism to be a heresy, eventually leading to the formation of the Christian Revival Crusade.

Article 23 of the AOG constitution declared "we cannot conscientiously participate in war and armed resistance which involves the actual destruction of human life, since this is contrary to ... the inspired Word of God".

James Wallace, an Assemblies of God minister from Great Britain, was appointed principal of the college in 1951 and was then elected AOG chairman in 1955, holding the post until 1959.

During his tenure, the college developed a central role in the fellowship and saw an increased number of pastors, church planters, and missionaries trained.

[30] Part of this growth was due to immigration, and ethnic congregations, including Slavic and Italian assemblies, were established.

This approach was successful and led to the 1973 turning over of all mission property and authority to local churches and the establishment of the self-governing Assemblies of God of Papua New Guinea which by 1998 rivaled the size of the Australian fellowship.

In 1963, the position of chairman was made a full-time one, and the constitution was reformed to make the AG's polity closer to that of the American Assemblies of God.

At the national conference of 1969, state presbyteries (governing bodies) were given more responsibility, the denomination asserted more control over ordination, and the title of chairman was changed to general superintendent.

New Zealand pastors such as Robert Midgley, Frank Houston, and Phil Pringle would significantly influence Australian Pentecostalism, and all ultimately moved their ministries to Australia.

Some AOG ministers responded with "new openness to ecumenical relationships", but others warned against "linking hands with modernists and liberals".

Both Australian Christian Churches and the Family First Party maintain that links are historical only, and that there is no organisational connection at the present time.

[45] Publicly the Assemblies of God in Australia has distanced itself from advocating certain political groups and parties, including the fledgling Family First party: In October 2007, a Today Tonight story said that several of the final remaining Australian Idol contestants were from Hillsong Church, raising concerns of vote-stacking by the church.
