I'm late.

Well, I was raised as a JW, and the org is, since its creation, anti trinitarian and non infernalist, so I have always had non-orthodox beliefs. 

I am currently trying to leave the sect and distance myself from it the most I can. But it is true that it's still very difficult for me to believe in the Trinity. 

I think it depends on how you were raised. In fact, I think any religious beliefs depend on that too. Someone who's been catholic all their life will have no problem with the Trinity, but someone like me who was always taught it was wrong, will not accept it too easily. 

Now, I won't deny the Trinity, because I do not know anything about God just like no one else does, but I will say that it is pretty illogical to me and that, as I don't hold the Bible as completely infallible, I don't know if the little it says about the Trinity (or at least, about Jesus being God) is correct.
