No Christians were nazis. They are two mutually exclusive belief systems. That is, the nazis stood for many anti-biblical beliefs. Somewhat akin to how a Christian cannot be a democrat.
Some nazis may have claimed to be Christian, but they were lying
Here is the program that people signed up to when they joined the NSDAP. And remember, like Republicans, not everyone accepts the entire platform:
1. We demand the unification of all Germans in the Greater Germany on the basis of the right of self-determination of peoples.
Not an anti-Christian concept.
2. We demand equality of rights for the German people in respect to the other nations; abrogation of the peace treaties of Versailles and St. Germain.
Very Christian (as we see it today).
3. We demand land and territory (colonies) for the sustenance of our people, and colonization for our surplus population.
Christians have been doing that for over a thousand years.
4. Only a member of the race can be a citizen. A member of the race can only be one who is of German blood, without consideration of creed. Consequently no Jew can be a member of the race.
Very Christian. You have to be a German Christian.
5. Whoever has no citizenship is to be able to live in Germany only as a guest, and must be under the authority of legislation for foreigners.
I wish we had this law today. Again, not against Christianity.
6. The right to determine matters concerning administration and law belongs only to the citizen. Therefore we demand that every public office, of any sort whatsoever, whether in the Reich, the county or municipality, be filled only by citizens. We combat the corrupting parliamentary economy, office-holding only according to party inclinations without consideration of character or abilities.
Excellent.
7. We demand that the state be charged first with providing the opportunity for a livelihood and way of life for the citizens. If it is impossible to sustain the total population of the State, then the members of foreign nations (non-citizens) are to be expelled from the Reich.
Socialist, but not necessarily anti-Christian, although expelling non-citizens is pushing it.
8. Any further immigration of non-citizens is to be prevented. We demand that all non-Germans, who have immigrated to Germany since the 2 August 1914, be forced immediately to leave the Reich.
Not great, but there is Christian precedent.
9. All citizens must have equal rights and obligations.
Excellent.
10. The first obligation of every citizen must be to work both spiritually and physically. The activity of individuals is not to counteract the interests of the universality, but must have its result within the framework of the whole for the benefit of all Consequently we demand:
Socialist, but Christian ("spiritually").
11. Abolition of unearned (work and labour) incomes. Breaking of rent-slavery.
Socialist, goes on the usury prohibitions.
12. In consideration of the monstrous sacrifice in property and blood that each war demands of the people personal enrichment through a war must be designated as a crime against the people. Therefore we demand the total confiscation of all war profits.
Not anti-Christian.
13. We demand the nationalization of all (previous) associated industries (trusts).
Okay, that's not good, but I don't see where Christianity bans it.
14. We demand a division of profits of all heavy industries.
Ditto.
15. We demand an expansion on a large scale of old age welfare.
Very Christian.
16. We demand the creation of a healthy middle class and its conservation, immediate communalization of the great warehouses and their being leased at low cost to small firms, the utmost consideration of all small firms in contracts with the State, county or municipality.
Neutral.
17. We demand a land reform suitable to our needs, provision of a law for the free expropriation of land for the purposes of public utility, abolition of taxes on land and prevention of all speculation in land.
Eminent domain, no property tax (yippie!), but there's the socialist bit on an end to speculation. Still, not anti-Christian.
18. We demand struggle without consideration against those whose activity is injurious to the general interest. Common national criminals, usurers, Schieber and so forth are to be punished with death, without consideration of confession or race.
Pro death penalty. Many Christians wouldn't consider that Christian.
19. We demand substitution of a German common law in place of the Roman Law serving a materialistic world-order.
Great, that's what we have, common law.
20. The state is to be responsible for a fundamental reconstruction of our whole national education program, to enable every capable and industrious German to obtain higher education and subsequently introduction into leading positions. The plans of instruction of all educational institutions are to conform with the experiences of practical life. The comprehension of the concept of the State must be striven for by the school [Staatsbuergerkunde] as early as the beginning of understanding. We demand the education at the expense of the State of outstanding intellectually gifted children of poor parents without consideration of position or profession.
We do it here, except for the monopoly part.
21. The State is to care for the elevating national health by protecting the mother and child, by outlawing child-labor, by the encouragement of physical fitness, by means of the legal establishment of a gymnastic and sport obligation, by the utmost support of all organizations concerned with the physical instruction of the young.
Protecting mother and child, very Christian. The rest is a bit socialist, but not anti-Christian, and with a good intention.
22. We demand abolition of the mercenary troops and formation of a national army.
Fine.
23. We demand legal opposition to known lies and their promulgation through the press. In order to enable the provision of a German press, we demand, that: a. All writers and employees of the newspapers appearing in the German language be members of the race: b. Non-German newspapers be required to have the express permission of the State to be published. They may not be printed in the German language: c. Non-Germans are forbidden by law any financial interest in German publications, or any influence on them, and as punishment for violations the closing of such a publication as well as the immediate expulsion from the Reich of the non-German concerned. Publications which are counter to the general good are to be forbidden. We demand legal prosecution of artistic and literary forms which exert a destructive influence on our national life, and the closure of organizations opposing the above made demands.
At the end there it mirrors a lot of Christians these days, ridding the country of publications with "distructive influence."
24. We demand freedom of religion for all religious denominations within the state so long as they do not endanger its existence or oppose the moral senses of the Germanic race. The Party as such advocates the standpoint of a positive Christianity without binding itself confessionally to any one denomination. It combats the Jewish-materialistic spirit within and around us, and is convinced that a lasting recovery of our nation can only succeed from within on the framework: common utility precedes individual utility.
Wow, for positive Christianity stated right there.
25. For the execution of all of this we demand the formation of a strong central power in the Reich. Unlimited authority of the central parliament over the whole Reich and its organizations in general. The forming of state and profession chambers for the execution of the laws made by the Reich within the various states of the confederation. The leaders of the Party promise, if necessary by sacrificing their own lives, to support by the execution of the points set forth above without consideration.
Simple consolidation of federal power. And notice it is only the party leaders who promise to support every point of this platform, not the rank and file.
