1,260 years of popery

This is a tough book. Notably, because this is, technically speaking, a sequel to Daughter of My People: Jesus' Jerusalem Destroyed. Why? Because Daughter of My People started because of me, a Seventh-day Adventist, reading The Great Controversy, whose first chapter deals with the second destruction of Jerusalem.
So this is a hard book because the next chapters in White's book are about the corruption of Christianity, the wickedness of the Catholic Church, and the virtues of the Protestant Reformation. So I know this will be a contentious book if I state my beliefs in the matter.
Why write this book anyway?
This book centers on history here-facts!
The book goes over the history of the Catholic Church from 533 to 1798. Why? Because in my Church, the RCC was predicted in prophecy from the Bible. Take Revelation 13:1-10, which refers to "The Beast from the Sea". The Beast here represents Papal Rome who "was given authority to continue for forty-two months". According to Numbers 14:34 and Ezekiel 4:6, in prophecy, one day represents a year. A Jewish month equals 30 days.
So 42 "30"s. 42 * 30 = 1,260.
And those are years.
Authority for the Papacy really started in 538 (although the word was given five years earlier) and was cut off ("mortally wounded") in 1798, when the French troops captured the Pope and put an end to Papal pride.
Yet Revelation 13:3 also notes that "his deadly wound was healed". It had started slowly with the Lateran accord of 1929. But as of me writing this (November 5, 2021), "his deadly wound" has not been healed in totality.
Some of the histories behind the Roman Catholic Church (and Christianity in general) are ridiculously tough and even painful to retell, but I attempt to get it clearly through within the pages of this book.
(Note: when I call the Catholic Church before the Schism of 1056 the "Roman Christian Church" or "Roman Church", I am not implying it was Christian at all-only Christian in name.)
