The Big Lebowski is one of the most quotable movies ever made and The Dude abides is one of the most memorable lines from the movie but it has a deeper meaning to unpack. Although it bombed at the box office and received mixed reviews from contemporary critics, The Big Lebowski has since become one of the cornerstones of cult cinema. It was initially dismissed as a laid-back screwball comedy full of profanity, but subsequent analysis has found a lot of underlying themes and the Biblical background of The Dude abides is a prime example.
