Bill Vallicella tackles the question of whether Christians and Muslims worship the same god. A good summary—and an apt demonstration of why Christians shouldn’t be too quick to make assumptions on this issue. Contrary to popular opinion among good evangelicals, it is not obvious that Allah and Yahweh must be different entities. A lot rides on your theory of reference—how you think names “attach” to the entities they refer to.
But here’s a possible counterargument. This perhaps sidesteps any theory of reference to demonstrate the thesis empirically—if puzzlingly vaguely:
- Christian worship is directed principally at Jesus
- Muslim worship is never directed at Jesus
- Therefore, Christians and Muslims principally worship different gods
