Lucifer's Editor

Richard Stallman notably produced the Emacs editor; its popularity rivaled that of another editor vi, spawning the editor wars; Stallman's humorous take on this was to jokingly canonize himself as "St. Ignucius" / "St. IGNUcius" of the Church of Emacs.

The Church of Emacs formed by Richard Stallman is a joke, and it refers to vi vi vi (which is 666 in Roman numerals) as the "editor of the beast".
