Pope John Paul II sums up the message of the fifth book of the New Testament:
The Acts of the Apostles indicates that the mission which was directed first to Israel and then to the Gentiles develops on many levels. First and foremost, there is the group of the Twelve which as a single body, led by Peter, proclaims the Good News. Then there is the community of believers, which in its way of life and its activity bears witness to the Lord and converts the Gentiles (cf. Acts 2:46-47). Then there are the special envoys sent out to proclaim the Gospel. Thus the Christian community at Antioch sends its members forth on mission; having fasted, prayed and celebrated the Eucharist, the community recognizes that the Spirit has chosen Paul and Barnabas to be “sent forth” (cf. Acts 13:1-4). In its origins, then, mission is seen as a community commitment, a responsibility of the local church, which needs “missionaries” in order to push forward toward new frontiers. Side by side with those who had been sent forth, there were also others, who bore spontaneous witness to the newness which had transformed their lives, and who subsequently provided a link between the emerging communities and the Apostolic Church.
Reading the Acts of the Apostles helps us to realize that at the beginning of the Church the mission ad gentes, while it had missionaries dedicated “for life” by a special vocation, was in fact considered the normal outcome of Christian living, to which every believer was committed through the witness of personal conduct and through explicit proclamation whenever possible.
The narrative of the book is really quite remarkable when a believer settles into it and absorbs the witness of the first generation of the Church.
