Hitler had been brought up a Catholic and was impressed by the organization and power of the Church. For Protestant clergy he felt only contempt: 'They are insignificant little people, submissive as dogs...[-] They have neither a religion you can take seriously nor a great position to defend like Rome'. It was the 'great position' of the Church that he respected; towards its teaching he showed only the sharpest hostility. In Hitler's eyes, Christianity was a religion fit only for slaves; he detested its ethics in particular. Its teaching, he declared, was a rebellion against the natural law of selection by struggle and the survival of the fittest.
