Through my personal experiences and research I've found the societies teachings closest to the foundational teachings and beliefs of the early apostles and the christian congregation.
The most foundational doctrine of the early church involved their relationship with Jesus.
I agree that the Trinity is a post-biblical development but The Watchtower's view of Jesus is radically different from that of the Apostles.
Jehovah's Witnesses View of Jesus Compared to the Early Church...
Conclusion from above link - In view of this sample of texts quoted above, it would seem reasonable to say that Jehovah's Witnesses do not speak about Jesus in the same manner as early Christians did. The apostles described themselves as witnesses of Jesus, they called him their only owner and Lord, and the one to whom they belonged. They were baptised in his name, led by his Spirit, rejoiced in his blessing and overflowed with praise for him. All of these statements are incompatible with the beliefs and practice of Jehovah's Witnesses. Even if an individual Witness may feel comfortable with such expressions they could never voice such sentiments in the hearing of others. There can be no doubt that if a Jehovah's Witness were to go back to a meeting of early Christians they would feel profoundly out of place.
