I do not know why I keep circling back to the question of whether Christians and Muslims worship different gods. Here is a video clip from Ergun Caner arguing for the opposing view, that we have different gods.
My question is simply this: why do we have to have our theology right in order for us to be worshipping the same god? It is easier to differentiate between Islam and Christianity. What about Roman Catholics and Protestant Evangelicals? Do we worship the same god? How about classical theists and open theists? Same god? Calvinists and Arminians? Same god? Fundamentalists and Evangelicals? Where exactly do we draw the line?
I cannot see any way around this logic:
A. Every one of us has erroneous theology to one extent or another.
B. If erroneous theology necessarily leads to false worship, then we all worship falsely.
C. At least some people do not worship falsely.
D. Erroneous theology does not necessarily lead to false worship.
