Well, for as long as the Catholic Church refused to allow the spread of the Bible to the general populace, it was not possible for "Baptists" to show up. Except of course, the original "John, the baptist."
See, for over a thousand years, the Bible was kept by the Catholic Church as a Latin-only treasure to be reserved for their own abuse. This sin was later corrected when the Bible was translated and made available to the general public, starting in roughly the 1500's.
What do you think it was that the Vatican was trying to hide from the people? God's Word? And... why?
