The PCA is structured according the Presbyterian system of church government. Local churches are led by a pastor (teaching elder) and elected leaders (ruling elders). The elders of individual churches collectively oversee a defined geographical jurisdiction called a presbytery. Presbyteries handle issues such as ordaining pastors, outreach, church discipline, and sending overtures to the General Assembly. The General Assembly is the annual meeting of all PCA presbyteries in the country. There are four PCA presbyteries in Alabama: Evangel Presbytery, covering the north-central region including Huntsville and Birmingham; Warrior Presbytery, covering the west-central region; Gulf Coast Presbytery, covering the Mobile area; and Southeast Presbytery, covering the south-central region including Montgomery. Evangel Presbytery and Warrior Presbytery were part of the original 16 founding presbyteries of the PCA in 1973.

By and large, the PCA is a socially conservative denomination. Disagreements over the extent to which the denomination should try to influence political and social life abound. Some leaders stress a commitment to the supremacy of the spiritual mission of the church. Others, however, support the view that, in addition to evangelism, the denomination should engage in reforming American political and social life. Some oppose political activtism, whereas others encourage it. For example, when Alabama Supreme Court Judge Roy Moore (a Baptist) covertly installed a Ten Commandments monument in the central rotunda of Alabama's state judicial building, D. James Kennedy, PCA pastor of Coral Ridge Presbyterian Church in Florida, provided a camera crew to record the event. Kennedy then sold videos to raise funds for Moore's legal defense. Although many PCA ministers and laypeople oppose using the pulpit for political ends, no action has been taken by the General Assembly to stop such activity.

The doctrine of the spirituality of the church, as well as a general tendency toward social conservatism, distinguished the southern from the northern Presbyterian church. By the 1930s, however, Progressive Era theological trends that arose in northern seminaries in the late nineteenth century began to migrate southward. Many ministers in the PCUS called for a reevaluation of certain denominational positions regarding the nature of scriptural authority. Equally problematic for conservatives were attempts to involve the denomination in progressive social and political causes. In 1934, the General Assembly of the PCUS established the permanent Committee on Moral and Social Welfare. Between 1934 and 1970, the committee issued a number of reports, papers, and calls to action on topics such as economic justice, poverty, marriage, divorce, sexuality, war, race relations, and civil rights.
Conservatives perceived these moves as indicative of increasing liberalism and modernism in the denomination. In 1942, they created the Continuing Church Movement (CCM), whose members saw themselves as defenders of orthodox Presbyterianism. The CCM supported traditional Calvinist theology and resisted all efforts to unite the PCUS with Presbyterian denominations they considered theologically suspect. Some members also vigorously defended the doctrine of the spirituality of the church. In 1954, the same year the U.S. Supreme Court ordered the desegregation of public schools, the General Assembly of the PCUS established a Special Standing Committee on Christian Relations. This committee published a paper entitled "The Church and Segregation" urging Christians to help bridge the racial divide. The committee commissioned similar reports throughout the late 1950s and 1960s. Conservatives argued these reports violated their commitment to the spirituality of the church, and they argued for maintaining the segregationist status quo by citing the view that the church had no place influencing political or social policy.
In the early 1970s, frustrated conservatives began devising a plan to withdraw from the PCUS without losing legal possession of their church property. This plan came to fruition in 1973. In February of that year, the Steering Committee of the CCM adopted a resolution to form a new denomination. In December, the first General Assembly of the PCA was called to order at Briarwood Presbyterian Church in suburban Birmingham and formally established itself as the National Presbyterian Church. The name was changed in 1974 to the Presbyterian Church in America after protest from a UPCUSA congregation of the same name in Washington, D.C.

Birmingham native Frank Barker pastored Briarwood Presbyterian Church on the southeast side of metropolitan Birmingham. The church orginally met in a storefront but by 1973 had grown to more than 1,500 members. Briarwood hosted a number of meetings of the CCM as well as the first PCA General Assembly. Barker served as the pastor of Briarwood until 1999, and during his tenure, the church constructed a $32 million campus. Today, with approximately 4,100 members, Briarwood is the largest PCA church in Alabama and remains one of the largest PCA churches in the nation. Briarwood is considered by many to be the flagship church of the denomination. In 2017, it garnered national media attention for its efforts to gain permission to establish its own police force from the state government.
