I understand the trinity doctrine perfectly well and make room for its veracity my friend.
Your assumption is that I am trying t discredit it in some way. That isn't so. I just want to see how Trinitarians react to their own idea that God has a God. It seems from the reaction that they are not too comfortable with it. Me? I would accept it as merely the way things are. Also, if indeed you are so knowledgeable-then you really have no cause to feel ill at ease with the concept.

About Unitarian claims?
Ironically they feel the same about Trinitarian claims.
Weird!
Me? I'm neutral!
