Dogma (1999)

Two fallen angels try to weasel their way back into heaven by using a loophole 

Bartleby and Loki are two angels who are eternally banished from heaven for disobeying the word of god. Eager to get through the gates of heaven, the angels come up with a plan to remit all their sins as humans, and find their way back home again in their next afterlife. The only thing stopping them from achieving success is God himself. Determined to stop the fallen angels, God, enlists the help of a low on life abortion clinic counselor, and two of his trusted prophets to catch the pair before they put their plan into action.
