When organized in 1913 Oakhurst affiliated with the Southern Baptist Convention, the Atlanta Baptist Association, the Georgia Baptist Convention and the Baptist World Alliance. Not all of these ties continue today.

In 1969 Oakhurst joined other Christian congregations in the Decatur area to establish the Decatur Cooperative Ministry to minister to the needs of people of the city in a variety of ways. One institutional spin-off from DCM is the Decatur Emergency Assistance Ministry.

In 1987 Oakhurst became the first church to affiliate with the newly formed Alliance of Baptists, a group of dissident moderates within the SBC who felt basic Baptist freedoms were being lost to fundamentalists. Sadly, the Alliance attracted only about 120 churches.

Then in 1991, a more representative group (about 1,500 churches) of moderate Southern Baptists formed the Cooperative Baptist Fellowship and directed its energies to missions. Oakhurst members were part of the founding of this organization, and the church has supported the CBF, though to a lesser degree than the Alliance. The church also participates in the Christian Council of Metropolitan Atlanta.

In 1992 the church moved to heal some of the division between Baptists North and South and affiliated with the American Baptist Churches in the USA, thus becoming active in American Baptist Churches of the South Area III.

In the Fall of 1999, differences between the Southern Baptist Convention and Oakhurst led to our separation from the Georgia Baptist Convention. See Oakhurst Responds to the GBC.

This action was followed in the summer of 2000 with a letter from the Southern Baptist Convention stating that because of the actions of the Georgia Baptist Convention, we were no longer considered a cooperating member of the SBC.

The latest chapter on affiliations closed in the fall of 2001 as these differences found their way to the local Atlanta Baptist Association. After months of dialog and discussion, and threats of being de-funded by the Georgia Baptist Convention and the Southern Baptist North American Mission Board, the Executive Committee of the ABA voted to remove Oakhurst from its rolls as of the first of November, 2001.
