Pope Leo: 'We are called to serve the People of God with our whole lives'
Pope Leo XIV celebrated the Mass of the Lord's Supper at the Papal Basilica of St. John Lateran on Holy Thursday. The Pope emphasized that priests are called to dedicate their entire lives to serving the People of God. Reflecting on the washing of the feet, the Pope highlighted Jesus's definitive love and the importance of serving those who are oppressed and in need. The homily marked the beginning of the Holy Triduum, focusing on the themes of Christ's passion, death, and resurrection.

The priest’s lifelong service exemplifies Christ’s model of love
The statement that a priest’s lifelong service exemplifies Christ’s model of love finds its deepest meaning in Catholic teaching: the priest is configured to Christ the Priest so as to make Christ’s own love present and communicable through word and sacrament, especially the Eucharist and the mercy of Penance, in a life marked by fidelity, prayer, and self-giving. That love is not sentimental; it is service, often carried out through sacrifice and perseverance.
In Presbyterorum Ordinis the Council explicitly ties priestly life to the “mystery of the Lord’s death” and to the Eucharistic sacrifice in which “the work of our redemption is being constantly carried on.” Priests are urged to keep their lives clean and ordered, so that in the Eucharist they truly “join in the act of Christ the Priest.”
The same document connects priestly imitation to a shepherd’s self-gift: priests are to be “aroused by the example of the Good Shepherd that they may give their life for their sheep.” In other words, the priest’s “model of love” is not an abstract ideal but the cruciform pattern of Christ’s Paschal love.
Pastores Dabo Vobis deepens this by grounding priestly identity in the communion that flows from the Trinity, and it presents Christ as the essential key for understanding the reality of priesthood: the priest’s identity is a “derivation” and participation in Christ, the one High Priest.
Finally, Pope John Paul II makes the Cross the interpretive center of priestly life: as Christ’s Priesthood is discovered in the mystery of the Cross, so also “the life of the priest derives its sense and purpose from this same mystery.” The Cross reminds priests of God’s personal love and pushes them to greater dependence on God in prayer and to accept the Father’s will with joy.
A common mistake is to reduce priestly love to private spirituality alone. Catholic teaching insists that the priest’s charity is inseparable from his sacramental mission.
Congregation for the Clergy explains that priestly identity is ordered to the service of Christ’s saving work in the Church; the priest “is the servant of Christ,” and his ordained being is the foundation for service. This identity is also described as Christological, ecclesiological, and pneumatological (a sharing in Christ’s saving work, in communion with the Church, under the Holy Spirit).
Presbyterorum Ordinis also stresses that priests, though not separated from others, cannot be “of service to men if they remain strangers to the life and conditions of men.” Yet their ministry “forbids that they be conformed to this world,” requiring them to live among people as true shepherds who lead others to Christ. So priestly love is both proximity and holiness—the love of one who belongs to Christ and therefore can truly serve others.
In CCC 1589, the Church gives a concentrated definition of the priesthood’s interior source:
“The priesthood is the love of the heart of Jesus.”
This matters because it tells you what the priest’s lifelong service is for: not self-promotion, but the transmission of Christ’s own love from the heart of Christ to the Church.
When the Council describes the priest’s deepest task, it does so in Eucharistic terms. In the Eucharistic sacrifice priests are not merely performing a ritual; they “fulfill their greatest task,” and therefore “the daily celebration of Mass is strongly urged.” Even when few faithful are present, it remains an act of Christ and of the Church.
The Council also highlights the priest’s love as mercy expressed in sacramental readiness, especially Penance: in the sacrament of Penance priests should show themselves “altogether and always ready whenever the sacrament is reasonably sought.” This is a clear way that lifelong love becomes lifelong availability to restore souls.
Beyond sacramental duty, Presbyterorum Ordinis teaches that priests grow in union with Christ through spiritual aids, especially those that nourish the Word and the Eucharist and through frequent recourse to sacramental grace, “especially sacramental Penance.” It also calls priests to mental prayer, vocal prayer, retreats, and spiritual direction. Without these, priestly love tends to become functional rather than transforming.
Pope John Paul II underscores perseverance as part of the integrity of priesthood: since priesthood is given to serve others, it “cannot be renounced because of the difficulties… and the sacrifices asked of us,” and priests must persevere “through the Cross.” That is precisely what it means to speak of “lifelong” service: love that continues when it is costly.
Pope Benedict XVI, in the opening of the Year for Priests, frames this same fidelity as “abide in my love,” and he connects priestly love to constant union with Christ and striving for holiness, following the example of Saint John Mary Vianney.
Christ’s love is not solitary. It builds the Church as communion. Presbyterorum Ordinis presents priests as leaders who cultivate unity: they lead the faithful toward “the unity of charity,” and they should reconcile differences so no one feels like a stranger in the community. The priest’s love is therefore social and ecclesial, aimed at belonging and reconciliation.
The Council also stresses doctrinal charity and vigilance: priests are “strenuous assertors of the truth,” so that the faithful are not “carried about by every wind of doctrine.” True love does not abandon truth—it protects souls within truth.
Importantly, the priest’s lifelong service includes honoring the laity and working with them. Priests should “invite [the laity]… to undertake works on their own initiative,” and they must recognize their experience and competence so that together they can recognize “the signs of the times.” This is an evangelical way of saying: priestly love creates space for God’s charisms in others rather than replacing them.
Finally, Congregation for the Clergy offers a vivid corrective to misperceptions: contemporary culture may reduce priests to roles like “therapist,” “politician,” or “manager,” but the Church insists the priest is at the very center of life because his priesthood has the capacity to enlighten, reconcile, and renew all things.
The Catholic vision of the priest’s lifelong service is consistent and demanding: Christ’s love—revealed in the Cross and made present in the Eucharist—becomes the priest’s pattern, while his identity as minister of salvation makes that love concrete through word, sacrament (especially Penance), prayer, and perseverance through difficulty. And because Christ’s love builds communion, the priest’s lifelong service also aims at unity, truth, reconciliation, and fruitful collaboration with the laity.
