I actually thought that it might be Dementia 13 for awhile. The description did seem to fit what I can recall of the movie. However the one I was looking at came out in the 1960's and I know this movie was not that old.

I did just happen upon another possiblity that sounds very much right (though I definately messed up some of the aspects of the movie is this is the correct one). Go to http://www.braineater.com/eternal.html and read about Spectre. The only problem I see is there doesn't appear to be any mention about the turkey attacking the priest (I just scanned the article though, so I could have missed it). You'd think a scene like that would have for sure been mentioned.
