This is my response to the critical commentaries by Hasker, McNaughton and Schellenberg on my tetralogy on Christian doctrine. I dispute the moral principles invoked by McNaughton and Schellenberg in criticism of my theodicy and theory of atonement. I claim, contrary to Hasker, that I have taken proper account of the ‘existential dimension' of Christianity. I agree that whether it is rational to pursue the Christian way depends not only on how probable it is that the Christian creed is true and so that the way leads to the Christian goals, but (in part) on how strongly one wants those goals. Hasker is correct to say that I need to give arguments in favour of the historical claims of Christianity, and I outline how I hope to do that. </P
