According to singer Ronnie James Dio, the song is about a man who is addicted to the Bible Black, a darkly twisted version of the Holy Bible, which ultimately corrupts and destroys him.[3]
Music video
A music video for the song was made and premiered on VH1 Classic as the first video of Metal Mania. It came on right after the season 2 finale of That Metal Show, which Ronnie James Dio and Geezer Butler of Heaven & Hell were guests on. The video is in animation and features the band via shadows. The premise of the video is an angel in Heaven picks up a black book (a'la the song "Bible Black"). When he opens it, it sends him down to Hell.
