More recent history: David Splane in an official presentation said that older anointed ones than Fredrick Franz, the near centenarian existed, exist. . Those 2groups, if overlapping by ~20 years, as Franz did in 1914, would bring the Great Tribulation to ~ 2075. Do the math. (2x100)- (2x20) = 160, +1914 = 2074 as rapture of the anointed generation, then battle in 2075. + 1000 = 3075, not 2975 as asserted above, beginning of final test.
cleaned those numbers up for you.
