Paul Berben wrote that insofar as the Christian denominations were concerned, Hitler declared himself to be neutral in Mein Kampfbut argued for clear separation of church and state, and for the church not to concern itself with the earthly life of the people, which must be the domain of the state. According to William Shirer, Hitler "inveighed against political Catholicism in Mein Kampf and attacked the two main Christian churches for their failure to recognise the racial problem", while also warning that no political party could succeed in "producing a religious reformation".
