I don't believe in this class stuff. However, when the GB discounts an "evil slave class" they are basically saying "We can't fail!". How presumptuous is that!! I remember Anthony Morris saying, in an almost ridiculing tone, "There is no wicked slave class that has arisen in these last days". (2014 AGM) This makes Jesus warning about an evil slave redundant....just hot air. I would love to see them explain the illustration from Luke's gospel, which describes the differing degrees of punishment for the unfaithful slave.
FusionTheism, you make some interesting points about the use of the word "illustration" and "classes" in the March WT. I will have to re-read it!! Do you think they will drop the term FDS "class"?
