The difference between 'democratic socialism' and what the OT and NT teach is that the giving is voluntary, and churches are indeed required to provide for widows and orphans and those in the flock who are ill and down on their luck. IT isn't 'democratic socialism' at all, but a function of the 'church' itself, to take care of their own.
On the other side of the coin, you can't be a 'social darwinist' asshat and be a Christian, and the Bible also says' a workman is worthy of his hire', a principle totally lacking in today's corporate business mentality, so right wing loons are out of luck as well.
But, as we've learned from real history versus fantasy history re Depressions, when churches are unrealistically expected to finance all of the unemployed or homeless, they will fall far short of being able to meet those needs and the government will have to step in sooner or later, since we also know the rich don't really give much to real charities, they like financing art museums and ballets and stuff that gets their names on buildings and in society columns. Most of those charities that serve the poor rely on mostly poor people themselves making donations and providing free labor.
