I was just discussing this excellent thread with my wife. During our last convention in 2014 we were perplexed by the constant mention of '100 years of Christ's rule'.
We had always been told Jesus would reign for 1000 years post armageddon. If he has in fact already reigned for 100 years then that would only leave 900 years providing the big A came that year. Seems like the orgs writers are getting confused on this whole 1914 and Christ's reign business.
