2. To remain faithful to the grace received! This gift of God does not cancel human freedom; instead it gives rise to freedom, develops freedom and demands freedom.

For this reason, the total trust in God's unconditional faithfulness to his promise is accompanied in the Church by the grave responsibility to cooperate in the action of God who calls, and to contribute toward creating and preserving the conditions in which the good seed, sown by God, can take root and bring forth abundant fruit. The Church must never cease to pray to the Lord of the harvest that he send laborers into his harvest, (cf. Mt. 9:38). She must propose clearly and courageously to each new generation the vocational call, help people to discern the authenticity of their call from God and to respond to it generously, and give particular care to the formation of candidates for the priesthood.

The formation of future priests, both diocesan and religious, and lifelong assiduous care for their personal sanctification in the ministry and for the constant updating of their pastoral commitment is considered by the Church one of the most demanding and important tasks for the future of the evangelization of humanity.

The Church's work of formation is a continuation in time of Christ's own work, which the evangelist Mark illustrates in these words: "And he went up on the mountain, and called to him those whom he desired; and they came to him. And he appointed twelve, to be with him, and to be sent out to preach and have authority to cast out demons" (Mk. 3:13-15).

It can be said that through her work of forming candidates to the priesthood and priests themselves, the Church throughout her history has continued to live this passage of the Gospel in various ways and with varying intensity. Today, however, the Church feels called to relive with a renewed commitment all that the Master did with his apostles -- urged on as she is by the deep and rapid transformations in the societies and culture of our age; by the multiplicity and diversity of contexts in which she announces the Gospel and witnesses to it; by the promising number of priestly vocations being seen in some dioceses around the world; by the urgency of a new look at the contents and methods of priestly formation; by the concern of bishops and their communities about a persisting scarcity of clergy; and by the absolute necessity that the "new evangelization" have priests as its initial "new evangelizers."

It is precisely in this cultural and historical context that the last ordinary general assembly of the Synod of Bishops took place. Dedicated to "the formation of priests in circumstances of the present day," its purpose was to put into practice the Council's teaching on this matter, making it more up - to - date and incisive in present circumstances, twenty - five years after the Council itself.( ³)
