No one is entitled to someone else's money just because they have more of it.
"Entitled" to, no.
But you don't get to go to heaven if you don't give it away, do you?
Luke 18:18-25
King James Version
18 And a certain ruler asked him, saying, Good Master, what shall I do to inherit eternal life?
19 And Jesus said unto him, Why callest thou me good? none is good, save one, that is, God.
20 Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother.
21 And he said, All these have I kept from my youth up.
22 Now when Jesus heard these things, he said unto him, Yet lackest thou one thing: sell all that thou hast, and distribute unto the poor, and thou shalt have treasure in heaven: and come, follow me.
23 And when he heard this, he was very sorrowful: for he was very rich.
24 And when Jesus saw that he was very sorrowful, he said, How hardly shall they that have riches enter into the kingdom of God!
25 For it is easier for a camel to go through a needle's eye, than for a rich man to enter into the kingdom of God.
Socialism and the redistribution of wealth from people with much to people with little is as Christian as apple pie, or some other mixed metaphor I'm not thinking of.
