1935 will soon be understood as marking the beginning of a "generation," and this whole circus act could go on for another 500 years;
The Society keeps getting the Memorial partaker numbers mixed up with the perdophile list;
Some congregations, anxious to elevate their stature in the circuit, are making up Memorial attendance and partaker figures;
The number 144,000 is symbolic after all;
As the org is progressively cleansed of apostates, the true spiritual status of closet anointed ones is being revealed.
