And potentially, free labour.
The body of Christ can be described as an organisation because a body is made up or organs. But a corporation is also a body, usually set up for the purpose of business.
The thing to examine is the relationships between the people. Are they based on love (as in brotherly love and a voluntary spirit) seeking the genuine well being of the other person or are they based on contract and money. Ok, WBTS does not use money. In their case they use a kind of enticement. I am not quite sure how to describe it. Social engineering? Priviledge? Mind control?
The point I want to make is that they are not seeking the other person's well being but their exploitation.
