4. In the ecclesial experience that is typical of the synod (i.e., "a unique experience on a universal basis of episcopal communion, which strengthens the sense of the universal Church and the sense of responsibility of the bishops toward the universal Church and her mission, in affective and effective communion around Peter"),(⁷) the voice of the various particular churches -- and in this synod, for the first time, the voices of some churches from the East -- were clearly heard and taken to heart. The churches have proclaimed their faith in the fulfillment of God's promise: "I will give you shepherds after my own heart" (Jer. 3:15), and they have renewed their pastoral commitment to care for vocations and for the formation of priests -- aware that on this depends the future of the Church, her development and her universal mission of salvation.

In this post - synodal apostolic exhortation, I take up anew the rich legacy resulting from the reflections, endeavors and indications which were made during the synod's preparation, as well as those which accompanied the work of the synod fathers, and as the bishop of Rome and successor of Peter I add my voice to theirs -- addressing it to each and every one of the faithful, and in particular to each priest and to those involved in the important yet demanding ministry of their formation. Yes, in this exhortation l wish to meet with each and every priest, whether diocesan or religious.

Quoting from the "Final Message of the Synod to the People of God," I make my own the words and the sentiments expressed by the synod fathers: "Brother priests, we want to express our appreciation to you, who are our most important collaborators in the apostolate. Your priesthood is absolutely vital. There is no substitute for it. You carry the main burden of priestly ministry through your day - to - day service of the faithful. You are ministers of the Eucharist and ministers of God's mercy in the sacrament of penance. It is you who bring comfort to people and guide them in difficult moments in their lives.

"We acknowledge your work and thank you once again, urging you to continue on your chosen path willingly and joyfully. No one should be discouraged as we are doing God's work; the same God who calls us, sends us and remains with us every day of our lives. We are ambassadors of Christ."( ⁸)
