Most people, not even most Jehovah's Witnesses, realize that the father of the International Bible Students, later named Jehovah's Witnesses, C.T. Russell, believed the coming of the Christ could be calculated by the measurements of the Great Pyramid of Gizeh (Thy Kingdom Come, Watchtower Bible and Tract Society).

This is evident from the stone pyramid with Masonic symbols at Russell's gravesite; placed there by the Watchtower Bible and Tract Society.
As a small child my father convinced me that my mother was demonized. And, though my father had abducted me and told many lies, he still served several congregations as an Elder for decades.
Many times through the years, my mother's husband, Jack, would ask the Witnesses, knocking on their door, to help find her son; they always declined. For, as far as they were concerned, my mother did not deserve the truth.
