Hello AA. Welcome to the forum.
I think one of the errors that the Watchtower has made is to denigrate the role of Jesus. I am convinced that the trinity is a post-biblical invention but it is also clear that early christians had a very different relationship with Jesus than modern day JWs.
If you are interested you could have a read at this old thread..
In summary - 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.
