In a work of fiction, I have an Order of ordained detectives that do not exist. I use the term Lictor Rebus Sanctorae for the Order, and Lictor Rebus Sanctorus for the male protagonist. I know this is very far off, and wish to get it right. He is officially a Sami Cupien, a Liaison between the Vatican and international officials, but is in fact more of a secret agent-type. I will appreciate any input, gratias tibi!
