His scepticism about much orthodox scholarship extended to a typically short but powerful critique of the German collection of essays "Kerygma and Myth" whose major contributor was Rudolf Bultmann. He averred, against them, that without the concept of miracle, the Christian project was fatally flawed, preferring the forms of existential defence of the faith of such as Gabriel Marcel to that of the Germans. His teasing style is indicated by his suggestion that Bultmann had freed the gospel from its fetters by amputating its limbs.
