Christianity like it or it not has been the core religion of many European nations for over a thousand years. It probably is what saved Europeans as a whole because it united small tribes by force into powerful nations that eventually become strong empires. When Europeans had to deal with Islamic aggression, the shared christian core is what brought nations together to fight back against the more foreign invaders. It also lead to bloody wars between European nations over sectarian differences that seem trivial or irrelevant to modern western nations.

Now that transportation is global and Christianity has spread to many non-white groups many see Christianity as a threat to the survival of Europeans. The religion is seen as being no longer European in character because it does not make distinctions between race which will lead to a nations destruction through miscegenation. To make matters worse, Christians don't seem to understand the nature of power or seem to care at all what happens in the world. Since they will be in heaven, why care about the environment or actually do anything that would stop Christians from being persecuted or practicing values that honor their god's will. Instead they just watch everything crumble around them and use copes like "it is all part of gods plan" for their impotence and lack of action.

The Third Reich attempted to create their own type of Christianity that removed the universal parts and the elements that deem contrary to their Aryan ideal. German Christians resisted these changes and formed movements like the confession church because they believed that their interpretation would be outlawed by the government or superseded by positive Christianity. How successful the Nazis were at removing the toxic influences of Christianity that threaten the nation state is questionable or even if it was necessary to begin with.

Probably the greatest issue is how does one unify different Europeans around a common philosophy that protects the interests of Europeans as a whole and the individual ethnic identities of each European nation. Christianity is declining in many European nations and this might be a good thing or a bad thing depending on whether it allows a new philosophy that leads to better people and also is compatible with protecting ethnic and racial interests of Europeans. The bad thing is what philosophy is capable of replacing Christianity that is not easily corruptible like liberalism and also it generally is not easy to get millions of people to give up a religion and convert to a new philosophy that is alien to their current degenerate lifestyles. The solutions are often anachronistic to the current time period or requires mass indoctrination that has to be carefully managed over multiple generations until the current weak spirit of the modern European man is extinct.
