There is one. Cult classic, Se7en. Though not a priest but more serial killer focused on the seven deadly sins.
Synopsis:
When retiring police Detective William Somerset (Morgan Freeman) tackles a final case with the aid of newly transferred David Mills (Brad Pitt), they discover a number of elaborate and grizzly murders. They soon realize they are dealing with a serial killer who is targeting people he thinks represent one of the seven deadly sins. Somerset also befriends Mills' wife, Tracy (Gwyneth Paltrow), who is pregnant and afraid to raise her child in the crime-riddled city.
I legit would like to have a movie with the concept of Confession of a Priest. Legit would watch (づ￣ ³￣)づ
