Just a thought...
Does the 2nd Baptism question, " Do you understand that your dedication and baptism identify you as one of Jehovah’s Witnesses in association with God’s spirit-directed organization?" enter the candidates into a legally binding contract?
This is a verbal declaration to abide by the "corporation rules" (disfellowshipping etc) said infront of witnesses (no pun intended).
Could it be that this is why this question was added? So that no-one has any legal comeback if their lives are changed by the society?
