I don't disagree with anything. There's nothing there to disagree with the fact that it's all the same God. Even Christians look at God differently. Catholics look at him through their saint's and Mary. Baptists try to ignore the fire and brimstone. Mormans add a native American flavor. Jews worship the same god without the assurity of forgiveness that Christ offered. Muslims see the crueler side of God from the old testement sharpened by Mohamed.
We all worship the same god, we just fight over His messagers (real or false).
You would think a real, all-powerful, all-knowing God would have enough of this foolishness to take five minutes out of His busy schedule and pop onto some mountain and speak for himself instead of going through unreliable middlemen with their own flaws and agendas.
