Abstract

Macnamara, La Palme Reyes, and Reyes have recently claimed to have shown decisively that the doctrine of the Trinity is internally consistent. They claim, furthermore, that their account does not commit them to any exotic emendations of standard logical theory. The paper demonstrates that they have established neither of these claims. In particular, it is argued that the set of statements they show to be consistent in fact expresses Sabellianism, not Trinitarianism; and that they can avoid this result only via commitment to the (questionable) doctrine of relative identity.
