The early church was not communist in any modern sense of the word. Still there were groups -like the one mentioned in Acts - who had an extremely apocalyptic view at the time. For them Jesus was coming soon (as in REAL SOON...their generation). There was not reason to invest far into the future. When time is short, you can sell every asset you own and just consume. Fortunately, many Christians did not go to such an extreme.
I heard those stories about how the early church expected the Second Coming of Christ immediately, but do not recall any actual Scripture to back this up... do you know where that is in the Word?
