In 1914, God & Jesus looked down on the earth and examined every Christian-based religion. During the next 4 years or so, they decided that a new religion created by a U.S. millionaire businessman (whose predictions of Armageddon & rapture failed miserably in 1914 & 1915) was the best of a bad bunch. In 1918-9, the religion was the subject of a coup d'état by a lawyer who used it as a great business opportunity. (but whose predictions of the Biblical resurrection in 1925 also failed miserably!) This was good enough for God and Jesus, so they decided that JFR and his cronies would be divinely appointed as "the faithful slave" within "God's earthly organization."
All of the above is factual and provable by scriptures! No arguments - otherwise I'll shun you.
