[GnnS13]

Ok i am new here and i want you to help me identify a specific movie.I saw some parts of it when i was a child and it really haunted me and now i try to find which movie is so that i could see it again. It was on old movie(70s or early 80s)and the style of that movie reminds me now a bit of Lucio Fulgi( Doesnt mean he was the director though).It was quite gory and the enemy was a supernatural priest or something. I remember specifically a scene were he puts his hand inside the throat of another character and you see his fingers moving through the neck as he removes the heart of the character.Or something like that.This scence is particularly memorable for the people who saw this movie so i am wondering whether you saw that one
