I remember a sister that was counseled because she had a painting(done by a worldy person) of Jesus in her house. "Form of Idolatry"
But....
What about the calenders that had paintings of Jesus, the apostles and others from bible times? Does that mean we can't hang those calenders on our walls? What about the mural at the Stanley Theatre(I think it was the Stanley)? What about the assembly halls that have mini-museums of old pictures and newspaper arcticles of Russell, Rutherford and the like? Is this not a form of idolatry?
You(the WTS) hang your pics of Russell or Rutherford, I'll hang posters of my favorite famous people and things.
