But they were attempting to govern as a theocracy, weren’t they? I know the 1st century Christians sold their goods, and “they held everything in common”, but that was because many of them were in hiding. Even so, he who won’t work, doesn’t eat, was the rule there.
I’m unsure why/how you are making a connection of the Islamic theocracy of government via the Koran to the first Christians. I was not making or implying of that. The first Christians were expecting Jesus to return shortly, thus they (some) sold their goods, etc.
Also the argument that first Christians were socialists is ill founded, for the reasons you stated.
The apostle Paul speaks of him earning his own way by making tents as he spread the gospel.
