Jude could be a person he communicated with. There are historical letters between scholars during that time. Maybe the user is referring to a PDF containing these letters, and they want a paper analyzing it. They mentioned a "drive link," so perhaps the PDF is available on a cloud storage like Google Drive or Dropbox. The user wants a paper based on that document.
