But let's talk about what Socialism actually entails.
Regardless of who you talk to, there are some basic fundamentals of Socialism that most Socialists could probably agree on. The first is the common ownership of the means of production.
Yes. Note that this is not necessarily state ownership--though they are often confused. Anarchist socialism (which holds there should be no state in the first place) envisions a network of cooperatives in which each enterprise is owned by those who work for the enterprise. IOW there is no separation between owners and labourers. The labourers are the owners. They provide both the capital and the labour. This is no different in principle from a self-employed businessman or partnership. It just involves a larger circle of self-employed owners.
Another would be ownership of local enterprises by local municipalities rather than by a national state. Or rather, all the citizens of a local town or city would be members of a cooperative which owned some local enterprises.
One place where this sort of socialism is currently being practiced with success is the Mondragon network of cooperatively-owned enterprises in Spain.
The advantage of worker-ownership is that workers who own the enterprise they work for are not likely to underpay themselves or force themselves to work in poor conditions.
This would require a radical re-adjustment of property rights;
Yes, just as in the early church, one would need to get back to the biblical idea that there is really no such thing as private ownership, for all belongs to God. We are tenants on God's property, stewards of God's creation, and responsible to God for how we apportion the fruits of the earth God has given us. That is why they chose to own all things in common.
for example, factories would need to be seized by the government in order to bring it under communal ownership. This is a big problem from a Christian perspective.
Actually, state intervention is not necessary to bring many enterprises under communal ownership. In Argentina, when many foreign investors abandoned their factories, the workers set up cooperatives and kept them running. In Canada when a US company decided to close down a pulp and paper mill, the union took over the mill and ran it as a cooperative with good success.
If the state takes over a business and then keeps the profit for itself rather than turning it over to the workers, that is a sham of socialism.
After all, doesn't the Bible say that we shouldn't steal?
Indeed, and is it not stealing when a rich corporation takes its marbles (dollars) out of the game and leaves people without employment rather than pay a decent wage or contribute to a pension plan?
Jeremiah had something to say to a king who coerced people into building a palace for him and then held back their wages.
And is it not stealing when financiers gamble with the investments people have made in their homes and after the banks have lost their money, they foreclose on those mortgages and turf people out of their homes?
When is someone going to be charged with that rash of thefts in your country?
How do you reconcile the need for a Socialist government to take (by force) the property of others with the Biblical commandment against theft? Redefining ownership doesn't make theft any more palatable.
How would you feel if someone came to claim your house and land because their grandfather owned it 50 years ago? Would you not call that theft?
Yet in Israel this is what God commanded.
How would you feel if you loaned someone money and after seven years they claimed they don't owe you anything any more? Would you not call that theft?
Yet in Israel this is what God commanded.
Maybe what we need is to redefine ownership more biblically.
Once a Socialist government is actually established, order must be kept. Socialist countries tend to adopt authoritarian policies because Socialism cannot work without authoritarianism.
You are cherry-picking evidence. There are many examples of socialist or social democrat governments which are not authoritarian. All governments have to keep order and have the authority to do so. All governments can be tempted to misuse that authority. Many governments, both socialist and non-socialist have misused that authority.
I think that a more Christian system would encourage strong social bonds and freely-given charity.
So far, so good. But the bible does not limit our obligation to providing charity. It also demands that we do justice; it particularly demands that those who hold the reigns of government (kings, judges, elders -- and in ancient Israel--priests) uphold and defend the rights of the poor.
So tell me less about charity and more about justice. Charity comes from individuals, but what is required at a government level--from local to national to international--is justice for all, protection of the weak from exploitation by the strong.
How would a Christian system ensure that everyone receives the justice of enough food and clean safe water for life, clothing and shelter, medicine and medical treatment as needed, education for the young so they can prepare to be responsible citizens, and training and retraining for those with disabilities or displaced by new technology---not to mention adequate time to spend with family and friends and to nurture their spiritual relationship with God. Are these not the minimally necessary things for a human life?
How, in your view, would a Christian system of government assure than no one is denied these things?
If the government mandates, at the threat of jail time, that you give all your money to the poor... is that as morally praiseworthy as giving money by your own free will?
A government cannot mandate charity. It can, however, forbid oppression and injustice. And it can use legal taxation (approved by the citizens) to implement programs to see that no one is deprived of their right to live in dignity.
It is by this criteria that God judges the nations: when many people are poor and hungry and without homes--that nation is not meeting God's standard of justice and will be so judged.
Cannot the richest country in the world meet this minimum standard of justice?
