The Papacy
Why Catholics Believe Christ Established the Office of the Pope
What Is the Papacy?
The Papacy is the office established by Jesus Christ when He entrusted a unique pastoral role to St. Peter among the Apostles.
The Pope is the Bishop of Rome and the successor of St. Peter, serving as the visible head of the Church on earth under Christ, who remains the true Head of the Church.
Catholics do not believe the Pope replaces Christ. Rather, the Pope serves Christ by guarding the faith and preserving the unity of the Church.
Peter’s Unique Role
Throughout the New Testament, Peter occupies a position of leadership among the Apostles.
His name appears first in apostolic lists, he frequently speaks on behalf of the Apostles, and Christ gives him responsibilities not given to others in the same way.
“And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.”
— Matthew 16:18 (Douay-Rheims)
The Keys of the Kingdom
In Matthew 16, Jesus gives Peter the keys of the Kingdom of Heaven.
“And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose on earth, it shall be loosed also in heaven.”
— Matthew 16:19 (Douay-Rheims)
In biblical tradition, keys symbolize governing authority.
This language echoes Isaiah 22, where the king appoints a chief steward to govern his household in his absence.
Catholics see Peter as holding a similar office within Christ’s Kingdom.
Strengthening the Brethren
Before His Passion, Jesus gave Peter a special mission.
“But I have prayed for thee, that thy faith fail not: and thou, being once converted, confirm thy brethren.”
— Luke 22:32 (Douay-Rheims)
Peter is entrusted with strengthening the faith of the other disciples, a role Catholics see continuing in his successors.
Feed My Sheep
After the Resurrection, Christ entrusted Peter with the care of His flock.
“Feed my lambs… Feed my sheep.”
— John 21:15–17 (Douay-Rheims)
Jesus, the Good Shepherd, commissions Peter to shepherd the Church in a special way.
This pastoral mission forms a key foundation for the papal office.
Did the Early Church Believe in the Papacy?
Yes. From the earliest centuries, Christians recognized the special authority of the Church of Rome.
St. Clement of Rome intervened in disputes outside his own local church near the end of the first century.
St. Ignatius of Antioch, St. Irenaeus, and many other Fathers testified to the importance of Rome and its connection to St. Peter.
The historical evidence demonstrates that the Church understood Rome to possess a unique role among the churches.
What About Bad Popes?
Catholics readily acknowledge that some Popes have been sinful men.
The doctrine of the Papacy does not teach that every Pope is personally holy or incapable of error in daily life.
Rather, Christ protects the Church from officially teaching error in matters of faith and morals when the Church teaches definitively.
The office is protected by Christ’s promise, even when its occupants are imperfect.
Why the Papacy Matters
The Papacy serves the unity of the Church.
Throughout history Christians have faced disputes over doctrine, morality, and discipline. The Pope acts as a visible sign of unity and a guardian of Apostolic teaching.
Catholics believe this office helps preserve the Church’s fidelity to Christ across the centuries.
