The church is one of two located in Camp Searchlight, this one occupying the western portion of the camp's map. In front of it, there is a Mark III turret next to some sandbags. The church itself consists of a single room that has lost most of its roof. When entering the church through the main gate, the player character can find a turret defense terminal on the left, giving them access to the turret that stands in front of the church.
The billboard in front of the church displays the Christian Bible verse Revelation 9:6, which reads, "And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them."  This is a reference to the ghoulified NCR soldiers and the quest We Will All Go Together.
The billboard used to read "BINGO EVERY TUESDAY NIGHT 6:30 9:30," which would account for why the "L" in "REVELATION" is actually an upside down "T."
