First of all we must face it: Jesus was a communist; so were his earliest followers after his death!
What then should are would-be followers of Yeshua the Christ to do? At least this:
Read Jose Miranda's manifesto, Communism in the Bible.
Or perhaps we might read Imagine: Living in a Socialist USA co-edited by Frances Goldin and recently featured on "Democracy Now!"
If we can't bring ourselves to sell what we have, give it to the poor, and live communally, at least conspire with like-minded people to share tools, automobiles, gardens -- and perhaps even jobs and homes in an effort to reduce poverty and our planetary footprints.
"Out" the "devout Catholic," Paul Ryan and other congressional "Christians" whose budgets attempt to balance federal accounts by increasing the ranks of the poor whose poverty the communism of the early Christian community successfully eliminated.
Pressure our government to get off Cuba's back and allow it to experiment in prophetic ways of living that can save our planet.
I'm sure you can add to this list. Please do.
