Alright, there is a movie that has been on my mind for a long while, but I can't remember the name of it. I know it involves at least 2 detectives, specifically two detectives I believe. They are investigating a number of killings that foretell the apocalypse I think it was. One involved them finding an eye on a bible.

The killings are being done by black robed monks in a cult of some sort. The detectives are often at their sanctuary, and only one speaks to them. The rest are said not to speak. The monks are often not harmed, one incident involved the detectives shooting one of the black robed monks in a store and removing a number of his fingers. The monk seemed to be invincible and not realize or feel this.

I believe its also a foreign film, French I think, as I believe it was subtitled when I saw it, I'm unsure though.

Anyone know what movie this is?
