Central to Christianity is the idea of service to others through voluntary poverty and sharing of worldly goods not commercial interactions. Jesus is not a capitalist. In saying this I should add nor is commercial interaction a sin. Nor is Jesus a Socialist because he does not advocate forcing a system on people. Though the system Christ advocates sounds like Socialism - it is one that has to be voluntary - Socialism uses the power of the State to enforce that condition. I would add that Jesus outlined one area where commerce should be banned outright and Jesus carried out a violent action to ban it himself - outside of the Temple of Jerusalem Jesus overturned the table of the money changers.
I will let Jesus' advice to the rich to give up his wealth pass without comment beyond adding what is capitalism but the accumulation of wealth?
No, listen, how can you share nothing?? What good is poverty to anyone??
No, God's plan is one of plenty for all. Our system is the best way to creat things to share. Through our desire to create we draw others into our plans and dreams and they propsper too.
Just think about it.
