Tertullian tells how the pagans say “See how they love one another” when they observe the fraternity that exists among Christians, and a few lines later he goes on to speak of the sharing of goods that is practiced in the church: “We who are united in mind and soul do not hesitate at all to share our property. Among us everything is in common except our wives.”
All the believers were one in heart and mind. No one claimed that any of his possessions was his own, but they shared everything they had. Acts 4:32
