The WTBS teaches nothing unbiblical that I know of.
HOWEVER, it 1- Has some very goofy opinions (as it has always had) as to what some of the prophecies mean, and
2- Lacking details on how the first congregations were run, have established some rules that cause many problems, and often hurt others.
As EVERY one of us have many flaws, on Organization has many more.
Judge us JWs and the WTBS all you want, as you play Judge- but the Truth stands on it's own- and you will NOT find it in Churchianity....
Apostatea, and atheists, as well.
