Socialism was not invented by Marx. Socialism existed in biblical times and long before Marx. I am speaking solely of the concept and the principles, not what Marx created and his version of it which is wrong. No such thing as Christian socialism? Wrong.
Christian socialism - Wikipedia
Socialism is a Christian concept, giving to others and sharing was taught by Jesus. Only America thinks capitalism is the Christian way lol. It's kind of funny how people can think greed is more Christ-like and always makes excuses like something is forced when in capitalism, you are being forced as well only not to give back to others but to give your money to corporations. If you think government rule means you are "forced" then you wouldn't like any system because since the beginning of civilization and in biblical times there were always government rule otherwise things would be chaotic, we do live in a fallen word after all and in the bible kingdoms were set up because that's just the way it is and how the world is.
Even in communist Yugoslavia, only 1% of the population were atheist. 99% were religious, and this is fact... Socialism actually has nothing to do with religion, but the concept is a lot more Christ-like than capitalism is.
