How many infinite transcendent-yet-immanent Creators of the cosmos can there be?

The article near the beginning says:

""believers in the One God", a phrase that assumes the word "God" to have the same referent in Islam and in Christianity."

This is ridiculous and really ought to be lost from Evangelical discourse. How can the referent be any other than the same? It may be that our understandings of some aspects of 'God' are different but that would be on a par with a dispute about whether one of my friends was, say, opinionated: no one seriously doubts the person in question is my friend; it is the way they act in some situations and how that is to be interpreted that is at issue.in reference to:
