Simultaneously with the movement to organize the Eastern Louisiana Association, many churches partly occupying the same territory, but principally situated near the Mississippi river, started another movement which resulted in the formation of the Mississippi River Association.
The first session of the new association met at Bethel Baptist church in Wilkerson County, Mississippi on October 20, 1843. The articles of faith which were adopted by the association indicated the waning influence of strict Calvinism among Baptists in the south. Rather than confessing the High Calvinism explicitly embedded within the influential Philadelphia Confession (1742), churches of the Mississippi River Association instead embraced the New Hampshire Confession of Faith (1843) adopted only months prior to the first meeting of the new association.
