We first meet Barnabas in Acts 4 when St. Luke, the author of Acts, says that the early Christians "were of one heart and soul, and no one said that any of the things that belonged to him was his own, but they had everything in common" (Acts 4:32). In our day, when diversity is trumpeted and even Christians seem to revel in how different they can be from one another, such a comment from St. Luke is quite the encouragement that there can indeed be something better. The unity of Christians in faith and life is indeed an encouragement and consolation.
We can indeed learn a lot from the early Church of Acts, and from Barnabas himself. As we are told of the early Christians selling their own property - perhaps the equivalent of "vacation homes" and extra land - we meet Barnabas in Acts 4:36: "Thus Joseph, who was also called by the apostles Barnabas (which means son of encouragement), a Levite, a native of Cyprus, sold a field that belonged to him and brought the money and laid it at the apostles' feet." What a great example of Christian charity! Barnabas saw the opportunity to use his wealth to proclaim Jesus Christ crucified and risen and to extend the kingdom of God. What great encouragement our Lord gives when His people give generously so that the Gospel may be proclaimed and His kingdom promoted.
