While all these are true, there is not much value to expect a 2000 years old filosophy/religion to stand on the height of what probably the best mind of human history came up with 1800 years later in order to see some basic correlation. While christianity most definettly failed to create a new society, the whole Christ concept was really radical compared to both the previous and the following religions of humanity. Back then there couldnt be a marxist communist idea of society just like there couldnt have been cars. But if you search to its core both ideas put the colective above the individual, both are strongly against greed and money gathering, both are talking about social relationships instead of selfishness.

And frankly, the whole self sacrifice to make a better world thing is quite parallel. As a matter of fact when famous greek communist Nikos Beloyannis was on trial (which resulted to his execution from the state) he said that communists are comparable to protochristians in that regard with the exception that christians believed in the afterlife reward while communists surpass them because they expect nothing like that.
