There is also the Catholic Changchung Cathedral in Communist North Korea; the nominal cathedral of the Roman Catholic Bishop of Pyongyang, North Korea.

Wikipedia:

Operation The cathedral is operated by the Korean Catholic Association and is not affiliated with the Holy See.[1][4] Because of the strained relations with the Holy See, the cathedral currently has no bishop or even an ordained priest.[3][2] There is no resident priest either. Masses are offered by foreign clergy.[1]

This doesn't scream "Christianity is okay in NK" to me.

Stalin openly worked with the Orthodox Church to help the Communist war effort for the Red Army during the second world war.

Okay. Sure.

Today in Russia, high ranking Clergy in the Russian Orthodox Church openly advocate a Christian Communist movement within their nation.

No duh. Most people made powerful will hold the same beliefs they had before and attempt to maintain that in their organization within that region.

There is nothing within the Christian doctrines or the teachings of the Nazarene that conflicts with communism in any way.

Nor is there anything outright promoting it.

Both programs work to enslave, using terror, brutality, mass murder and coersion.

That's practically every religion, cult, and dictatorship, among several other things.

Christians are indoctrinated to believe that poverty is a virtue. Once this concept takes hold upon one's subconscious mind, quite often, a serious lack of money is a result and this sometimes even lasts into future lives, speaking from a spiritual perspective. What this does is it also creates a self-perpetuating program, and in turn creates generations of poor. The Christian Churches then appear as helpers of the poor and benefactors, when all along, it was the Christian teachings that created and enforced the problem.

It could also be argued to be intentionally created by capitalism just as much as communism. Removing money from people by selling false promises doesn't remove that money from the system. It makes particular people incredibly rich in the process. Not exactly a pure-communistic idea. Same with the eye-of-a-needle people quote.

As for

prohibit the ownership of private property.

I don't know enough about the bible, but I'm gonna need something more than "poor is a virtue" somehow equals "never own anything."

There is nothing at all spiritual about Christianity.

The site says that's not spiritual, then immediately:

replacing these with meaningless robotic 'prayers' corrupted from and repeated

I can't think of a single faith that doesn't repeat something. Even so, I don't think repetition somehow disqualifies the spirituality from the practice.

Christianity also prepares followers for communism in that one is indoctrinated to endure injustice. Nearly everyone has heard the biblical scriptures about turning the other cheek, walking the extra mile, loving one's enemies and so forth. These teachings work together with communism in destroying the justice system and personal rights.

What does any of that have to do with Jews?

Communism's Christian Roots

All this web page says is that some Christians were communist. It also disregards all the capitalist Christians.

I don't think there's enough evidence on that site to support it's theory.

Edit: Am an atheist, so hopefully someone with a better knowledge of the subject can correct me if I've missed something here.
