Ahem, I am sorry but socialism is not related to Christianity, but a distortion and an evil extention of charity through government. As this communist would say: " I do not want charity business but social justice."
1. Charity in Christianity is handed out to those who are charitable to themselves: i.e. help those who want to do good, i.e. but do not help those who ask you to help them party or sniff drugs. Socialism makes no difference as to whom receives the help. Government is not about sanctioning morality but productivity at best, and, then, not even so, because the productive tax payer is not encouraged by the welfare system it views with suspicion and on which it has little control.
2. When the socialist government owns the means of production, how can one distinguish a punishing government from one who hands out jobs? If a felon wants to revenge against government, then, as an employee of government, the felon can sabotage the workplace. On the other hand, if private and public are separated, if the punishing entity differs from the job handing entity, we do not have such criminal Marxist subversion of government possible. One becomes his own government and jurisdiction with his own private and local public means to oppose government in legal checks and balances. In Judeo-Christianity this is called "let my people go" or the "crucifiction", all selfinsulation from sin and taking the fall for future generations' sake and salvation, as opposed to a socialism which enslaves and destroys any hope of slavation, separation and washing of past sins and evils, a new improved world at every generation. The way the socialists plan things for everything precludes people from learning from their mistakes. People only make mistakes that the state views as mistakes and live in a world completely disconected from reality and real mistakes, but mistakes as seen by the state.
3. Also the planification nature of socialism implies the same deal as Plato, whereby the state of life is enforced philosophicaly and can only be argued philosophicaly through superliterate "proofs" in all virtuality that are not related to reality. Compare that to Christ's more optionable and market oriented idea of a virtualy private government you choose, who said "you will know them by their fruits", and one sees quickly how results and free choice beats any proof or any enforced philosophy that precludes choice and real life testing of those choices - if ever those choices are difficult and may lead one to personal catastrophy, taking the fall is the idea. Compare the tenured professor who has no respect for the poor with gut instincts and no education but who through goodness and instinct is able to survive and build an empire of his own to become rich. This is the result of true charity vs. philosophical self defeating alibis and human laboratory experiments to do harm to others. One is responsible for himself and is his own lab, let not others be involved with such experiments against their will or through "scientific" deceptions and alibis.
