On an episode of “Standing Up For The Truth with Mike Lemay”, it was claimed that experiments in Christian communal living in the 1960's and 1970's fizzled out because the participants became materialistic and wanted their own possessions. But is that really sinfully materialistic or merely the way that God has wired human beings to maximize individual well being? The sharing of resources mentioned in Acts 2 is more a description of a specific historic incident. It is not elaborated as categorically imperative doctrine.
