"In those days, as the number of disciples grew, the so-called Hellenists complained against the so-called Hebrews, because their widows were being neglected in the daily distribution. So the Twelve summoned the whole body of disciples together, and said, 'It is not right, that we should neglect the word of GOD to serve at tables. So, friends, choose from among yourselves seven respected men, full of Spirit and wisdom, that we may appoint them to this task. As for us, we shall give ourselves to prayer. and to the ministry of the word.'
The whole community agreed; and they chose Stephen, a man full of faith and the Holy Spirit; Philip, Prochorus, Nicanor, Timon, Parmenus and Nicolaus of Antioch, who was a proselyte. They presented these men to the apostles, who, first prayed over them, and then, laid hands upon them.
The word of GOD continued to spread, and the number of the disciples in Jerusalem increased greatly; and even many priests accepted the faith." - Acts 6:1-7
(JESUS did not spell out for HIS apostles how they were supposed to organize the Church. And a conflict arose between two social groups. The Jews, called Hebrews, had never left their land and they spoke Aramaic. The Hellenists were those who had lived abroad and who usually spoke Greek. They may have followed the Essene movement and refused to participate in temple rituals. They felt uncomfortable with the liturgy and community life and their frustrations were growing. In fact, the apostles identified more readily with the Hebrews and it became necessary to give some autonomy to the Hellenists with their own people being in charge. This was probably the birth of a Greek-speaking church, with a Greek liturgy.
The community chose seven men. Since their authority had to come from CHRIST, it had to be passed on by the apostles.
The candidate must be filled with faith and the Holy Spirit, because they are not only entrusted with material services. And even if it were only for material services the Church would have much to suffer from competent administrators who lacked the Spirit of the Gospel. Were these seven men the first deacons? Luke mentions nothing beyond service, and "deacon" denotes servant, usually steward. In fact, this term, "deacons," will from the start give the meaning of every ministry in the Church: ministry means "service" [1 Corinthians 12:15]. Ministers are at the service of the community assembled by the Spirit to witness to the salvation given by JESUS. All through the centuries, the ministers of the Church would be tempted to misuse the role entrusted to them for the good of the community. Many will take advantage of their "service" to put themselves over the community: they will let others serve and honor them and will not hesitate to be called princes of the Church. What is true for those called to a high rank in the hierarchy is equally true for all those priests or lay people entrusted with lesser responsibilities: all must remember the words of JESUS [Luke 22:24-27].)
