“All those who became believers were together and had everything in common, and they were selling their possessions and properties and distributing the proceeds to all, according to what each one needed.”
~Acts 2:44,45

Were the first Christians practicing an early form of Communism?
The story of the first Christian congregation relates that they went from 120 members to over 3,000 people in a single day. (Acts 2:41,47)
Many of those people were from far away and had not originally planned to extend their stay in Jerusalem, but that is what they ended up doing in order to learn more about Christ. (Acts 2:5-11,42)
The generous Christians knew that very soon, they would be persecuted and eventually, Jerusalem would be destroyed, so their possessions would be lost. (Acts 8:1)
Their material things were put to better use because they had a sense of urgency, not because of a philosophical ideology.
While donations were administered by the congregation, property owners could choose how to manage their own assets. (Acts 2:46; 5:1-4)
Later on, a formal distribution was arranged for the benefit of widows only. (Acts 6:1-3; 1 Tim. 5:16)
Christians were always encouraged to share, even after the congregation had been well established. (Acts 20:35; Jas. 2:15-17)
But the fact that there were still class distinctions indicates that the congregation did not redistribute wealth as a rule. (Rom. 12:13; 15:26; 2 Cor. 9:7)
