For the writer of the book of Acts, the holy Apostle Luke, was also among the companions of the holy Apostle Paul.
By dignity, the name of Barnabas appears in the book of the Acts of the Holy Apostles after the eleven, Matthias, and Justus. For among earlier workers it is difficult to point to anyone equal to him.
There is testimony that Barnabas left the island of Cyprus early and studied under Gamaliel together with the young Saul.
He was the nephew of Mary, the mother of John Mark (see Acts 12:12). In her house he often saw Jesus Christ, and still more often in the Jerusalem temple.
After Jesus Christ departed to Galilee, he too followed Him and was among His seventy disciples.
Probably he was called Barnabas, that is, son of consolation, because of his great gift to the Church. Perhaps it was also because of his special gift for comforting those who suffered and were burdened by needs of every kind, especially spiritual needs.
After many apostolic labors in different countries, in Antioch and Milan, he suffered martyrdom in Salamis, being stoned. This was after the destruction of Jerusalem.
John Mark buried him and placed in his tomb the Gospel according to Matthew, copied by Barnabas’ own hand. It was found together with his relics, incorrupt, in the year 488, under Emperor Zeno.
Some Western scholars see in the repetition of the account concerning the inner condition of the earliest Church the narrator’s use of a source different from the one he used when writing chapter 2.
In refutation of this unjust opinion, a specialist researcher on the book of Acts says the following.
“As a skilled writer, Saint Luke, by this remark, or repetition, wishes to point out the hidden foundation of the conquering power living in the first Christian community. This power is rooted in the spirit that penetrates and animates Christians.
“With the disclosure of a hostile attitude toward Christians, external security for the Christian community was destroyed.
“If the ‘communion of possessions’ had then been a consequence of the community’s happy condition, and had not been rooted in the unshakable foundations of the spirit, the new turn of events would have struck it a severe blow.
“The fact that the communion of possessions is again confirmed by the narrator of Acts must be new proof for us that its foundations must be sought in the inner constitution of the community.
“And if so, the sacred writer did not need to seek anything better to testify to the inner vital energy of the community, and to its invincibility before the persecutions that were beginning.
“He could simply limit himself to a new indication of the communion of possessions as the most characteristic manifestation of the spiritual power living in the first community.
“And so he did. Thus there is nothing unnatural in Saint Luke’s repetition of one and the same description of the state of the earliest Church.
“This in no way speaks against the unity of the writer of the whole work.
“In vain do they see a contradiction between this depiction of the state of the earliest community and the discord between Hebrew Christians and Hellenists over the assistance given to widows; see Acts 6:1 and following.
“In early Christian usage, ‘communion’ (koinonia) means communion of faith and love; see Phlm 1:6; 2 Cor 13:13; 1 Jn 1:7.
“It has the meaning of close communion of persons; see Gal 2:9. It is expressed in giving to the poor; see Rom 15:26, and in doing good to them; see Heb 13:16.
“Its motto was: ‘Not to each his own, but to each what is mine.’ The holy Apostle Barnabas, who himself gave up his estate, says in his epistle, ‘Share everything with your neighbor, and do not call it your own property’ (19:8; compare The Teaching of the Twelve Apostles, 4, 8).”
