I'm looking for a movie, but can really just remember one scene.
The main character is (I think) a policeman or private detective. However, he had studied to become a catholic priest. But on the day of his ordination as priest - as he lay prone on the floor and other priests are doing the ritual - he had terrible visions of a war in Heaven among angels... so he abort his calling. Someone comments to him that most who doesn't become priests does it because they lacked faith - but he dropped out because he had too much.
I don't really remember anything else, but I assume there is a war in Heaven and that it spills over onto Earth, and that the main character had to stop it.
