OK, not Communism with a capital C, all grim and totalitarian, but “communism” as in communal living. Barrett appears to have extensive involvement in a Christian intentional community, People of Praise, an organization both Charismatic and mostly Catholic, in which members practice communal living. According to the Pedia of Wiki,

Members attempt to live as much of a common life as possible, working together, praying for one another both privately and in groups, visiting one another, sharing meals and offering one another gifts of money and material items in times of need. For some members common life extends to working together in community sponsored businesses and outreaches. Most members are married couples, including many with growing children. Some married couples have single men and women living with them in “households”, but most do not. Some single people live together (in houses of single men or women) while some live by themselves. There are also celibate single men and women, some of whom have formed a Brotherhood and Sisterhood within the People of Praise.
