Mass: Heaven on Earth-Mass is revealed in the Apocalypse. In the Book of Revelation Jesus is called the Lamb of God 28 times in 22 chapters. Dr. Hahn enlightened us to the fact that the only thing in Revelation on every page is the Liturgy. White robes, songs, prayers. Every page of every chapter the Heavenly Liturgy corresponds to the Earthly Mass. The Rite of Communion is the Marriage feast of the Lamb. I have studied Revelation before, but never seen it in this way until now.
