The Alleluia Files is a science fantasy novel by American writer Sharon Shinn, published in 1998.

[2] Generations ago, religious people built a colony spaceship called Jehovah.

The colony ship, orbiting above, was able to provide supplies and services.

These were accessed by genetically modified 'angels', who were the only ones capable of performing the right vocal tones.

Over the generations, the concept of the ship was forgotten and it was believed Jehovah was an actual deity.
