First Baptist Church of Jax, Jacksonville

The First Baptist Church of Jacksonville is a large Southern Baptist church located in downtown Jacksonville. With its current membership at 28,000 and with an average attendance of around 7,500 for Sunday services, it is the third largest in the Southern Baptist Convention. First Baptist Church has its origins in the oldest Baptist congregation in Jacksonville, Bethel Baptist Church, established in 1838.

The church experienced a period of considerable growth in the mid-20th century, and now encompasses eleven square blocks of downtown Jacksonville. Several former pastors, including Homer G. Lindsay, Jr. and Jerry Vines, were widely influential in the Southern Baptist Convention, leading it in both growth and a shift towards conservatism and fundamentalist Christianity.
