The math never worked.
Estimated 1st century Christians to about 320AD = 7,000,000
Estimated martyrs during that time = 2,000,000 (due to heavy persecution)
Add the faithful to death in the following 1500 years the estimate is many millions more.
I read Foxe's Book of Martyrs when I left JW. The persecution was cruel and horrendous, nothing like what the JW "faithful slave" has gone through. (My favorite martyr, Perpetua, sniff) Boiling oil thrown on then, skinned alive, fed to wild animals... I knew for sure the JW interpretation of the little flock was BS.
Just do the math with any adjustments to the estimated numbers...the math does not support the JW dogma. And at some point they were going to have to down play the number.
This is just my take on the whole thing.
PS. My brother, elder, kept track on spread sheets the numbers reported in the annual report. There were some years I think in the 70's that the WT did not report the partaking numbers. He knew something was up.
