Interestingly I heard the brother at our hall use the term "slave class" from the platform, but I was in the back doing other stuff and thought it was odd considering the "new light".
Well I just read over the lesson and that class term isn't in there unless I missed it. So the brother was really confusing the audience at our hall it appears.
Also even though the brochure is from 2012, it seems to already be in line with the then-future new light in its ambiguous description of who the slave is.
That is unless they have already revised it? I am looking at the one from jw.org. Anybody know if it has been changed from the original release?
