I saw this one movie maybe ten years ago. All i can recall is a group of people in a house, demons were trying to get in. The only way the group seemed to fight the demons was by using the blood of Jesus or something; i believe they somehow had his heart actually. I remember them using it to seal doorways and if the demons tried passing through they would just disintegrate. I liked the movie but was only about ten at the time so i can't remember the name. Any help would be appreciated
