Adam Clarke Bible Commentary

The Church which was in Jerusalem - This was the original, the mother Church of Christianity; not the Church of Rome; there were Christian Churches founded in many places, which exist to the present day, before Rome heard the Gospel of the kingdom. A Christian Church means a company of believers in Christ Jesus, united for the purposes of Christian fellowship, and edification in righteousness. They sent forth Barnabas - It seems, then, that the Church collectively had power to commission and send forth any of its own members, whom it saw God had qualified for a particular work. There must have been, even at that time, an acknowledged superiority of some members of the Church beyond others. The apostles held the first rank; the deacons (probably the same as those called prophets, as being next chosen) the second; and perhaps those called evangelists, simply preachers of the truth, the third rank. Those who knew most of God and sacred things, who were most zealous, most holy, and most useful, undoubtedly had the pre-eminence.
