It is interesting that you mention the trinity. Well, no it isn't specifically mentioned in the bible (as with so many other things) but it came about as it is the only solution to the identity of Jesus and God the Almighty. Jesus said many, many things that identified himself as deity. This, despite what you have been taught by the WT cannot be ignored. If you read the book of Revelation it becomes very obvious that Jesus and God are one and the same. This is what the bible says, not what I say. Let it speak for itself!
How can this be so when Jesus said that the Father was greater than he?
Well, at that particular time he was of course.
In short, what I am saying is, don't be put off or stumbled by all of the red herrings that the WT has churned out.
The Christian faith is not an easy thing to grasp when you have had your mind poisoned by the Watchtower (I should know) but try to give it the benefit of the doubt and look at it objectively and without predjudice.
I wish you the best.
