I heard this on the radio just a few days ago.
Jesus told the rich young ruler to go and sell everything he owned and give the money to the poor.
If he had been a Communist he would never have told the guy to 'sell' everything he owned.
Communism did not exist in those days. Jesus was not suggesting that the government ought to FORCE you to share your belongings. He was suggesting that people ought to do so out of the goodness of their hearts. That's what Jesus cared about--your heart.
