Seeker, wow, thx for all those links! Though I didn't ask the question, I appreciated the answer

Vivian, if you can get your hands on "The Lamb's Supper" by Scott Hann, I think you'd understand & love the Holy Mass more than you probably already do.
To quote Hann from the book: "The Mass--and I mean every single Mass--is heaven on earth." Literally" Hann also says that Catholic liturgy offers the best interpretive paradigm for studying the Book of Revelation.
Blessings,
