The Church founded by Jesus Christ on the apostles, the first bishops, came before the Book of Revelation.
So? What the Roman Catholic church celebrates today as the "Mass" was certainly not practiced in the first century! To imagine that John fashioned the book of Revelation modeled on the RC Mass is bogus. The RC church tried to model the Mass on what was spoken of in the book, not the other way around. The rationalization of taking snippets of Scripture and crowbarring them into some proof-text of the Mass having divine origins is a myth.
Yep.
