Pope Leo in apostolic letter calls for renewed priestly formation, fraternity, and mission

ACI Prensa Staff, Dec 22, 2025 / 12:07 pm (CNA).

Pope Leo XIV calls for renewed priestly formation, stronger priestly fraternity, and a more missionary focus in pastoral ministry in an apostolic letter released by the Vatican on Monday.

The document, “A Fidelity That Generates the Future,” reflects on two decrees of the Second Vatican Council: Optatam Totius — on priestly formation — and Presbyterorum Ordinis — on the ministry and life of priests — both promulgated in 1965. Leo urges Catholics to keep reading the two conciliar texts in Christian communities and to study them “particularly in seminaries and in all places of preparation and formation for ordained ministry.”

An apostolic letter is a formal papal document, typically addressed to the Church, meant to teach, encourage, or direct pastoral priorities on a specific theme.

In his new letter, Leo says the Church is not simply marking an anniversary. He writes that the council’s “desired renewal” remains closely tied to priestly ministry, quoting the council’s assessment that “the desired renewal of the whole Church depends to a great extent on a priestly ministry animated by the spirit of Christ.”

The pope presents fidelity as both a grace and “a constant journey of conversion,” and he thanks priests worldwide for their ministry — from celebrating the Eucharist and proclaiming the Word to caring for those who suffer.

Formation and the abuse crisis

Leo writes that every vocation begins with an encounter with Christ and recalls the Lord’s call, “Follow me” (Mk 1:17). He says fidelity in “times of trial and temptation” is strengthened by remembering “the sound of the voice of the Lord who loves, chooses, and calls us,” and by seeking the accompaniment of those experienced in the spiritual life. 

Addressing what he calls “the crisis of trust in the Church caused by abuses committed by members of the clergy,” the pope says the scandal “has filled us with shame and called us to humility” and underscores “the urgent need for a comprehensive formation” that fosters human maturity alongside “a rich and solid spiritual life.” 

He urges seminarians to examine their motivations and includes a pointed line on formation of the heart: “The seminary is meant to be a training ground to help a seminarian attend to his own heart… we need to learn how to love and how to do so as Jesus did.” 

Priestly fraternity and loneliness

Leo describes priestly fraternity as a gift rooted in ordination itself and warns against individualism. He encourages practical steps to strengthen bonds among priests, including support for those who are isolated, sick, or elderly.

The pope also flags disparities that can undermine communion, saying more remains to be done — including “economic equalization between those who serve poor parishes and those who carry out their ministry in wealthy communities.”

Synodality and shared leadership

Leo calls synodality “particularly close to my heart,” arguing that the Church still has work to do in fostering healthy relationships between priests and bishops, among priests themselves, and with the lay faithful. 

He encourages priests to engage the Synod on Synodality’s final document and says priestly ministry should move away from “exclusive leadership” that centralizes parish life and places every responsibility on the priest alone. Instead, he points to more collegial leadership and cooperation among priests, deacons, and the whole people of God. 

Mission and the temptations of activism and withdrawal

The pope links priestly identity to mission and warns against two temptations: an efficiency-driven mindset that measures worth by performance, and a “quietism” that retreats from evangelization. He writes that media exposure and social networks require discernment and recalls St. Paul’s warning: “‘All things are lawful for me,’ but not all things are beneficial” (1 Cor 6:12). 

The letter closes with a focus on vocations and the need for both prayer and renewed pastoral creativity. Leo entrusts seminarians, deacons, and priests to the intercession of the Immaculate Virgin, Mother of Good Counsel, and St. John Mary Vianney.
