1. A priestly, sacramental, prophetic community, the Church was established by Jesus Christ as a structured, hierarchical and ministerial society, in function of the pastoral governance for the formation and continuous growth of the community. The first subjects of this ministerial and pastoral function are the twelve Apostles, chosen by Jesus Christ as the visible foundations of his Church. As the Second Vatican Council says, "Jesus Christ, the eternal Shepherd, built up the holy Church and sent the Apostles as He Himself was sent by the Father (cf. Jn 20:21), and He willed that their successors, that is, the bishops, should be shepherds in His Church until the end of time" (LG 18). This passage from the Dogmatic Constitution on the Church - Lumen Gentium - reminds us first of all of the original and unique position of the Apostles in the institutional framework of the Church. From the Gospel story we know that Jesus called disciples to follow him and from among them he chose twelve (cf. Lk 6:13).

The Gospel narrative lets us know that for Jesus it was a decisive choice, made after a night of prayer (cf. Lk 6:12); a choice made with a sovereign freedom: Mark tells us that Jesus, having ascended the mountain, called to himself "those whom he wanted" (Mk 3:13). The Gospel texts record the names of the individuals called (cf. Mk 3:16-19 et par.): a sign that their importance was perceived and recognised in the early Church.

2. By creating the group of the Twelve, Jesus created the Church, as a visible structured society at the service of the Gospel and the coming of the Kingdom of God. The number twelve referred to the twelve tribes of Israel, and Jesus' use of it reveals his intention to create a new Israel, the new people of God established as the Church. Jesus' creative intention transpires from the same verb used by Mark to describe the institution: 'He made twelve . . . He made the twelve'. "Make" recalls the verb used in the Genesis account about the creation of the world and in Deutero-Isaiah (Is 43:1; 44:2) about the creation of God's people, ancient Israel. The creative will is also expressed in the new names given to Simon (Peter) and James and John (Sons of Thunder), but also to the group or college as a whole. Indeed, Luke writes that Jesus "chose twelve, to whom he gave the name of apostles" (Lk 6:13). The Twelve Apostles thus became a characteristic, distinct and, in some respects, unrepeatable socio-ecclesial reality. In their group emerged the Apostle Peter, about whom Jesus manifested more explicitly his intention to found a new Israel, with the name given to Simon: "stone", on which Jesus wanted to build his Church (cf. Mt 16:18).

3. Jesus' purpose in establishing the Twelve is defined by Mark: "He made twelve of them to be with him, and also to send them out to preach, and that they might have power to cast out demons" (Mk 3:14-15). The first constitutive element of the group of the Twelve is therefore an absolute attachment to Christ: they are people called to "be with him", that is, to follow him, leaving everything behind. The second element is the missionary element, expressed on the model of the mission of Jesus himself, who preached and cast out demons. The mission of the Twelve is a participation in Christ's mission by men closely linked to him as disciples, friends, trustees.

4. In the mission of the Apostles, the evangelist Mark emphasises "the power to cast out demons". It is a power over the power of evil, which in a positive sense means the power to give men the salvation of Christ, the One who casts out the "prince of this world" (John 12, 31). Luke confirms the meaning of this power and the purpose of the institution of the Twelve by quoting the word of Jesus giving the Apostles authority in the Kingdom: "You are the ones who have persevered with me in my trials. And I lay down for you a kingdom as the Father has laid down for me" (Lk 22:28). Also in this statement, perseverance in union with Christ and the authority granted in the kingdom are intimately linked. It is a pastoral authority, as is evident from the text on the mission specifically entrusted to Peter: 'Shepherd my lambs . . . Shepherd my sheep" (John 21: 15-17). Peter personally receives supreme authority in the shepherding mission. This mission is exercised as participation in the authority of the one Shepherd and Master, Christ. The supreme authority entrusted to Peter does not cancel the authority given to the other Apostles in the kingdom. The pastoral mission is shared by the Twelve under the authority of the one universal Shepherd, mandatary and representative of the Good Shepherd, Christ.

5. The specific tasks inherent in the mission entrusted by Jesus Christ to the Twelve are the following: a) mission and power to evangelise all nations, as the three Synoptics clearly attest (cf. Mt 28:18-20; Mk 16:16-18; Lk 24:45-48). Among them, Matthew highlights the relationship established by Jesus himself between his messianic power and the mandate he gave to the Apostles: "All power in heaven and on earth has been given to me. Go therefore and make disciples of all nations" (Mt 28:18). The Apostles will be able and must carry out their mission by the power of Christ manifested in them. b) mission and power to baptise (Mt 28:19), as the fulfilment of Christ's mandate, with a baptism in the name of the Most Holy Trinity (Ibid), which will be the first baptism in the name of the Most Holy Trinity (Ibid). Trinity (Ibid), which, being linked to the paschal mystery of Christ, in the Acts of the Apostles is also considered as baptism in the name of Jesus (cf. Acts 2:38; 8:16). c) mission and power to celebrate the Eucharist: "Do this in memory of me" (Lk 22:19; 1 Cor 11:24-25). The commission to redo what Jesus accomplished at the Last Supper, with the consecration of the bread and wine, implies a power of the highest level; to say in the name of Christ: "This is my body", "this is my blood", is almost an identification with Christ in the sacramental act. d) mission and power to forgive sins (Jn 20:22-23). It is a participation of the Apostles in the power of the Son of Man to forgive sins on earth (cf. Mk 2:10): that power which in Jesus' public life had caused the astonishment of the crowd, of which the evangelist Matthew tells us that they "gave glory to God who had given such power to men" (Mt 9:8).

6. To fulfil this mission, the Apostles received, besides power, the special gift of the Holy Spirit (cf. Jn 20:21-22), which was manifested at Pentecost, according to Jesus' promise (cf. Acts 1:8). By virtue of this gift, from the moment of Pentecost they began to fulfil the mandate of evangelising all peoples. The Second Vatican Council tells us this in the Constitution Lumen Gentium: "The Apostles . . . preaching everywhere the Gospel, accepted by the hearers through the motion of the Holy Spirit, gather the universal Church, which the Lord founded on the Apostles and built on blessed Peter, their head, while Jesus Christ himself is its cornerstone (cf. Rev 21:14; Mt 16:18; Eph 2:20)" (LG 19).

7. The mission of the Twelve comprised a fundamental role reserved for them, which would not be inherited by others: to be eyewitnesses of the life, death and resurrection of Christ (cf. Lk 24:48), to transmit his message to the primitive community, as a hinge between divine revelation and the Church, and for this very reason to initiate the Church in the name and by virtue of Christ, under the action of the Holy Spirit. For this function of theirs, the Twelve Apostles constitute a group of unique importance in the Church, which since the Niceno-Constantinopolitan Symbol is defined as apostolic (Credo una sanctam, catholicam et 'apostolicam' Ecclesiam) because of this indissoluble link to the Twelve. This explains why also in the liturgy the Church has included and reserved special solemn celebrations in honour of the Apostles.

8. However, Jesus conferred on the Apostles a mission of evangelisation of all nations, which takes a very long time, and indeed lasts "until the end of the world" (Mt 28:20). The Apostles understood that it was Christ's will that they should provide successors, who, as their heirs and legates, would carry on their mission. They therefore established "episcopes and deacons" in the various communities "and arranged that after their death other approved men should receive their succession in the ministry" (Clement of Rome, Ep. Ad Cor., 44, 2; cf. 42, 1. 4). In this way Christ established a hierarchical and ministerial structure of the Church, formed by the Apostles and their successors; a structure that did not derive from a previously established community, but was created directly by him. The Apostles were, at one and the same time, the seeds of the new Israel and the origin of the sacred hierarchy, as stated in the Council's Constitution Ad Gentes (AG 5). This structure therefore belongs to the very nature of the Church, according to the divine plan realised by Jesus. According to this same plan, it has an essential role in the entire development of the Christian community, from the day of Pentecost to the end of time, when in the heavenly Jerusalem all the elect will fully participate in the 'New Life' for eternity.
