If you could name some names and give links to any Christians claiming that, then I would simply have to answer that they are completely wrong.
Everyone knows he was brought up as a Catholic. Then as he grew in political power, he formed plans to change Christianity into a neo-pagan religion. A Professor Overy wrote the book “The Dictators”. He is Professor of History at King’s College, London. He shows that Hitler’s private views on Christianity “betray a profound contempt and indifference.. Hitler, like Stalin, took a very modern view of the incompatibility of religious and scientific explanation.”
Here are a few of Hitler’s remarks on the subject, recorded by Martin Bormann within hours of the Fuhrer uttering them: “The heaviest blow that ever struck humanity was the coming of Christianity.” (11-12 July 1941)
“The best thing is to let Christianity die a natural death.” (14 October 1941)
“The war will be over one day. I shall then consider that my life’s final task will be to solve the religious problem... The organised lie must be smashed.” (13 December 1941)
Hitler despised the Bible and Christianity. He, like Stalin, only ever appeared supportive if that would further his politically demonic ends. His mind was corrupt and evil – and he hated the Bible.
“The best thing is to let Christianity die a natural death.... When understanding of the universe has become widespread... Christian doctrine will be convicted of absurdity.... Christianity has reached the peak of absurdity.... And that’s why someday its structure will collapse.... ...the only way to get rid of Christianity is to allow it to die little by little.... Christianity the liar.... We’ll see to it that the Churches cannot spread abroad teachings in conflict with the interests of the State.” (p 49-52) “Hitler’s Secret Conversations 1941-1944” published by Farrar, Straus and Young, Inc., first edition, 1953
Hitler later produced plans to form a new Pagan Nazi church called the "National Reich Church," and outlawing all other religions. The new religion's 30 point program included:
1. The National Reich's Church of Germany categorically claims the exclusive right and the exclusive power to control all churches within the borders of the Reich; it declares these to be national churches
5. The National Reich Church is determined to exterminate irrevocably and by every means the strange and foreign Christian faiths imported into Germany in the ill-omened year 800.
13. The National Reich Church demands immediate cessation of the publishing and dissemination of the Bible in Germany as well as the publication of Sunday papers, pamphlets, publications and books of a religious nature.
14. The National Reich Church has to take severe measures in order to prevent the Bible and other Christian publications being imported into Germany.
15. The National Reich Church declares that to it, and therefore to the German nation, it has been decided that the Fuhrer's "Mein Kampf" is the greatest of all documents. It is conscious that this book contains and embodies the purest and truest ethics for the present and future life of our nation.
16. The National Reich Church has made it its sacred duty to use all its energy to popularize the coeternal "Mein Kampf" and to let every German live and complete his life according to this book.
18. The National Reich Church will clear away from its altars all crucifixes, Bibles and pictures of Saints.
19. On the altars there must be nothing but "Mein Kampf", which is to the German nation and therefore to God the most sacred book, and to the left of the altar a sword.
22. The National Reich Church repudiates the christening of German children, particularly the christening with water and the Holy Ghost.
24. The National Reich Church abolishes confirmation and religious education as well as the communion the religious preparation for the communion.
30. On the day of its foundation, the Christian cross must be removed from all churches, cathedrals and chapels within the Reich and its colonies and it must be superseded by the only unconquerable symbol of Germany the "Hakenkreuz" (swastika).
