Three books in one with over 850 pages, carefully researched and written by Edwin de Kock, an historian, theologian and writer. There is no other book like it. The first section traces the papal title, Vicarius Filii Dei (vicar of the Son of God), through some 100 Catholic sources and the calculation of it’s numerical value of “666” by nearly 70 Protestants and non-Protestants. The next section traces historically the apostasy of the church and it's change of the Sabbath and the establishment of Sunday-keeping. It uncovers the historical conflict between the church of Rome and Sabbath-keeping Christians, as the church sought to eliminate the Sabbath and establish Sunday. The research is vital to a proper understanding of the book of Revelation and the beast of chapter 13. This landmark book with it’s in-depth historical documentation is a vital volume for every sincere student of prophecy. It comes with a CD so the book can be copied to a computer hard drive.
