I just read a wiki page on Jehovah's witnesses, visited their official website, and was quite surprised that in the list of their believes there is a striking absence of the definition (or at least description) of their concept of the Church.
According to what I can see at the moment, they are only using the word "church" or plural "churches" in reference to the numerous religious groups in the main-stream Christianity (which they consider all to be in apostasy), while they themselves prefer to speak about the Kingdom, rather than the Church.
Is it a result of their special translation of the Bible (in which many words were translated quite differently from the way it is done in the majority of Bible translations, for example, in many places the word that is translated in other translations as "fellowship" in their translation is rendered as "sharing") or am I simply missing out on something here?
What's their concept of the Church? What's their teaching on the Church? When did it start? How long has it been around? Has it always existed since it was started or, perhaps, it was over at some time and then re-stated again?
