Why do Catholics have a Pope?

As Catholics, we entrust the guidelines of our faith to be drawn and governed by a single person in particular, the Pope. This has famously been a topic of disagreement throughout Church history and the cause of rebellion and breaks within the Christian community. In this article, I will use magisterial and biblical evidence to explain why Catholics chose to believe in and follow the Pope as our visible, earthly Father.

In the Gospel, Jesus gives Simon the name Peter and says:

“You are Peter, and upon this rock I will build my Church… I will give you the keys of the kingdom of heaven.”

St. Basil the Great wrote that all of the apostles fulfilled their duties and were integral to God’s plan, but Peter was given the specific and special job to “Presided over the other disciples.” This moment was more than just an honorary title given to Peter, it was a distinctive, authoritative role that set the very foundation of the Church.

After the Resurrection, Jesus also entrusts Peter with the care of the whole flock: “Feed my lambs… Feed my sheep.” The Pope’s office is understood as the continuation of this ministry. He serves as Peter’s successor in being the sturdy rock that the Church stands on as well as the caretaker of God’s people.

Christ established one Church. One body designed to unite in faith, worship, and communion. The heir of Peter act as a visible sign of this oneness; he is the point to which all Catholics can look to as a sign of solidarity and unity.

This is also why Catholics speak of being in communion with the Pope. Unity with the Pope is not simply loyalty to a particular personality; it signifies communion with the worldwide college of bishops and with the Church’s apostolic faith.

Since Peter ministered and was martyred in Rome, the Roman bishop came to hold the Petrine office, but that is not meant to claim that bishops and the rest of the faithful are passive subjects. The Pope and the rest of the bishops resemble Peter and the other apostles. The Pope is the head, while each bishop acts as the shepherd of a particular diocese.

The Pope’s role includes:

guarding the unity of the Church;

confirming the bishops and faithful in the faith;

teaching on faith and morals;

addressing the needs of the universal Church;

governing the Church’s common life and discipline.

We hear that the Pope can speak “infallibly” or “without error,” however, the scope of his infallibility is much narrower than just that. The Pope is not sinless, omniscient, or incapable of making mistakes. Papal infallibility applies exclusively to definitive declarations on faith and morals, not daily governance, political opinions, or private theological views. It has been invoked explicitly very few times in history, but Catholics believe that it is truly a gift given from the Holy Spirit to keep the Church rooted in truth and protect her from spreading false doctrine.

The Pope is sometimes called the Vicar of Christ, meaning a representative who acts in Christ’s name, not someone who takes Christ’s place. Christ remains the one Head and Shepherd of the Church. The Pope’s authority is entirely received from Christ and exists to serve Christ’s people.

This service should be modeled on Jesus, who exercises authority through humility, sacrifice, and love. Cardinal Ratzinger emphasized that the authentic exercise of papal authority must resemble Christ’s self-giving and obedience, rather than worldly domination.

The Pope, then, is not supposed to be a monarch pursuing personal power. He is charged with carrying the burden of serving the Church’s unity, protecting the apostolic faith, and helping the Church fulfill her mission.

In conclusion, the Pope does not replace Jesus. Catholics have a Pope precisely because we believe Jesus chose to appoint a visible figure to lead and guide his Church as one united, faithful body. Peter was the first person chosen to fulfill this role and his successors act in his place as the Church's guiding figure throughout history.
