One thing I notice from sitting through a number of broadcasts is just how much these guys love their titles. It's always Brother Such-and-Such, member of the GB, helper to the teaching committee, etc. It's never simply Brother Such-and-Such, a local elder with Such-and-Such congregation.
It seems to me the witnesses are pretty quick to pick up on Catholics who call their priests father, which at the end of the day is in much the same vein simply a title.
I suspect these titles point to a huge amount of narcissism of the part of those who revel in such titles, certainly it doesn't seem to fall in line with Christ's advocation that the greatest amongst you should be be the least.
