That God could have not created the world is a commonplace of Christian theology, often invoked to articulate the meaning of divine freedom. This essay argues that this counterfactual predication cannot be made consistent with the classical doctrine of God and so cannot be an adequate way of characterising God’s freedom. Drawing on a critical realist account of coherent counterfactual predications, it is shown that every cogent counterfactual attribution implies that the subject of the attribution is located in time, possessed of potential, and knowable in its essence. These entailments of counterfactual predications render them formally incompatible with a classical theist doctrine of God, in which God is not temporally located, purely actual and unknowable in essence by humans in the status viatoris. If the counterfactual on divine predicating compromises the divine simplicity, divine perfection and divine pure actuality, it should be understood to be a metaphorical, not substantial divine predication.
