Thank you for writing this article. I have been a student of the Great Apostasy that occurred after the establishment of the Christian church by Jesus Christ for over 40 years. I have done extensive research and have written my own book on the subject. As you have stated, the collection of this research has nothing to do with trying to make the Catholic Church look bad or to offend individual members of the Catholic Church, many of whom I know to be being up-standing, respectable Christians as the on-going cooperation in humanitarian efforts between The Church of Jesus Christ of Latter-day Saints and the Catholic Church confirms. The question is what evidence is there that an apostasy occurred and when I began my research I had no idea where it would lead. I found that the evidence is overwhelming that an apostasy occurred (as all Protestants agree) and that the restoration of valid authority to represent Jesus Christ (priesthood) was essential.
