"Jehovah himself was born??"
Nice catch. JWs believe that Jehovah had no beginning.
Plus, saying that Jehovah is the Messiah tends to support the Trinity belief, since Jesus was the Messiah. The problem is that JWs clearly believe that Jehovah and Jesus are two different individuals.
They (the GB) should have left that one off the list of 'J Versions', since it raises a bigger problem than it solves, and as a result tends to shoot them in the foot.
