One more thing…Scott Hahn wrote a book called “The Lamb’s Supper: The Mass as Heaven on Earth”. I have not read this myself but I have a friend who loved it.
Part of a description of the book says:
The Lamb’s Supper reveals a long-lost secret of the Church: The early Christians’ key to understanding the mysteries of the Mass was the New Testament Book of Revelation. With its bizarre imagery, its mystic visions of heaven, and its end-of-time prophecies, Revelation mirrors the sacrifice and celebration of the Eucharist.
