2. Paul Helm Eternal God (Oxford: Clarendon Press, 1988); idem The Providence of God (Leicester: InterVarsity Press, 1993).
3. In what follows I shall provide page references to Eternal God as EG, and to Peter Byrne's chapter, ‘Helm's God’, as HG.
4. Paul Helm ‘God does not take risks’, in Michael J. Peterson and Raymond J. Vanarragon (eds) Contemporary Debates in Philosophy of Religion (Oxford: Blackwell, 2004), 235. ‘Willing permission’ is one standard way of characterizing God's ordaining of what is evil that notes the need to preserve an asymmetry between God's attitude to good and evil: He brings about evil by willingly permitting it. See also Paul Helm ‘The Augustinian-Calvinist view’, in James K. Beilby and Paul R. Eddy (eds) Divine Foreknowledge: Four Views (Downers Grove IL: InterVarsity Press, 2001), 180.
5. There are other places in his piece where Byrne appears to disregard qualifications that are present in my original text. Thus my phrase in Eternal God, ‘a universe which is in some sense the inevitable outcome of God's choice which is itself in some sense inevitable’ (EG, 182) becomes ‘The universe is the inevitable outcome of an inevitable choice’ (HG, 194).

7. It seems to me that ‘openness theism’ deviates so sharply from standard Christian theism as to warrant a distinct response.

9. Alvin Plantinga ‘Supralapsariansm, or “O felix culpa”’, in Peter van Inwagen (ed.) Christian Faith and the Problem of Evil (Grand Rapids MI: Eerdmans, 2004). In her ‘Plantinga on “felix culpa”: analysis and critique’, Faith and Philosophy, 25 (2008), 123–140, Marilyn McCord Adams raises the standard objections: Hitler, Stalin, and Pol Pot.
