Rather than discussing many different teachings of the Jw's, I would like to suggest that we consider what is the most important issue, namely, the person of Christ.
Jw's and I both believe that Jesus Christ was a perfect man and that He is a person distinct from God the Father. However, Jw's teach that before His earthly life, Christ was a spirit creature, Michael the archangel, who was created by God and became the Messiah at His baptism.
According to the well-known Jw's publication Let God Be True (p. 33), Jesus is “a mighty one, although not almighty as Jehovah God is.” According to John 1:1 in your Bible, The New World Translation, Christ is “a god” but not “the God.” In other words, Jw's teach that Jesus “was and is and always will be beneath Jehovah” and that “Christ and God are not coequal” (The Watchtower, 15 April 1957).
Does the Bible substantiate these statements, or does it teach that Christ is God? This is an extremely important question.
I would like to raise the following points.
First of all there are several Bible verses that specifically affirm the deity of Christ. In Matthew 1:23, Christ is called “Immanuel,” which means “God with us.” When Thomas touched the wounds of the risen Lord, he exclaimed, “My Lord and my God!” John 20:28
There is no basis whatsoever for saying, as some Jehovah’s Witnesses say, that Thomas was referring to Christ when he said “My Lord” but was referring to God the Father when he said “my God.” Instead Thomas called Christ both his Lord and his God, and Since Christ did not correct him it had to have been a true statement.
Colossians 2:9 clearly confirms the deity of Christ, when it states that in Him “all the fullness of the divine quality dwells bodily”
