Do Muslims and Christians worship the same God? We answer: it depends. To begin, we clear away some specious arguments surrounding this issue, to make room for the central question: What determines the reference of a name, and under what conditions do names shift reference? We’ll introduce Gareth Evans’s theory of reference, on which a name refers to the dominant source of information in that name’s “dossier,” and we then develop the theory’s notion of dominance. We conclude that whether Muslims’ (...) use of “Allah” co-refers with Christians’ use of “God” depends on how much weight is given to what type of information in the dossiers of these two names, and we offer a two-part test by which the reader can determine whether Muslim and Christian uses of the divine names co-refer: If Christianity were true and Islam false, might “Allah” still refer to God? And: If Islam were true and Christianity false, might “God” still refer to Allah? We explain the implications of your answers to those questions, and we close with a few reflections about what, in addition to reference, might be required for worship, and whether, from a Christian perspective, salvation turns on this issue.

The word ‘God’ is typically thought to be a proper name, a name of a defined entity. From another position it appears to be a description that is fundamentally synonymous to ‘the first of all causes’, or ‘the font et origo of the structure of possibilities’, or ‘the provenience of being’, or ‘the generator of existence’. This lends credence to the view that ‘God’ is a truncated definite description. However, this article proposes that ‘God’ is a name given to whatever (...) is that which is the first of all causes, the font et origo of the structure of possibilities, the provenience of being, the generator of existence. If so, then it is a descriptive name. Yet even among descriptive names ‘God’ is unique, for it is neither convertible to a proper name, nor to a definite description. ‘God’ is an inveterate descriptive name. (shrink)
