"The Mighty God": Jehovah's Witnesses Betrayed by Their Own "Bible"

"For a child has been born to us, 
A son has been given to us; 
And the rulership will rest on his shoulder. 
His name will be called Wonderful Counselor,  
Mighty God, Eternal Father, Prince of Peace."

This is Isaiah 9:6 in the New World Translation (2013 revision), the Bible published by the Watchtower Society, or, as they are commonly called, the Jehovah's Witnesses. Why am I quoting their version? Have I suddenly converted? No, of course not.

I am quoting it because  the Watchtower has accidentally made an important confession here.

If you discuss this verse with a Witness, he will agree that it refers to Jesus Christ. However, they claim that it only teaches that Jesus is a "mighty god" (note lower case), just as they say about John 1:1. He is not the Almighty God, Jehovah.

Their problem is that they forgot to amend the next chapter of Isaiah. In Isaiah 10:21, the NWT refers to Jehovah as "the Mighty God." So, if their interpretation of 9:6 is correct, then they must also teach that Jehovah is not "the Almighty God," but just "the mighty god." In other words, their interpretation of the their own version requires them to say that God is not God!

Why do they insist so strongly in this particular heresy? I have thought long on that question. The Watchtower won't give an honest answer to it, of course. But I think it is that our God, the incarnate I Am (John 8:58), is powerful for the complete salvation of all His people. But, by hiding that great salvation, the Watchtower Society keeps its members in bondage, looking to Brooklyn for salvation. The Catholic Church uses a similar strategy, not by denying the deity of Christ, but by denying the infallibility and perspicuity of the Bible. Different roads to the same goal!
