The Papacy

The Papacy is the supreme jurisdiction and ministry of the Pope as shepherd of the whole Church. As successor of St. Peter, Bishop of Rome, and Vicar of Christ, the Pope is the perpetual and visible principle of unity in faith and communion for the whole Church (CCC 882).

The Foundation in Scripture

The papacy is rooted in Christ's words to Peter: "You are Peter, and on this rock I will build my Church, and the gates of hell shall not prevail against it. I will give you the keys of the kingdom of heaven" (Matthew 16:18–19). Christ also commanded Peter to "feed my lambs" and "tend my sheep" (John 21:15–17). The Church sees in these texts a unique authority entrusted to Peter and his successors (CCC 881).

Papal Infallibility

The Pope is infallible when, acting as shepherd and teacher of all Christians, he defines a doctrine of faith or morals to be held by the whole Church. This charism applies to solemn doctrinal definitions — not to everything a pope says or writes. Papal infallibility was formally defined at the First Vatican Council in 1870 (CCC 891).

Primacy of Service

The Pope's authority is a primacy of service, not domination. The title "Servant of the servants of God" (Servus servorum Dei) — used by popes since Gregory the Great — reflects Christ's own teaching that the greatest must be the servant of all (Mark 10:44; CCC 894).

Frequently Asked Questions

Was Peter really the first Pope? Yes. The Catholic Church teaches that Peter held a unique primacy among the Apostles and that the Bishop of Rome succeeds to this role. Historical evidence from the earliest centuries consistently honors the bishop of Rome with a primacy of authority (CCC 881–882).

Can a Pope be deposed? Under Catholic canon law, no earthly authority can judge or depose the Pope. A pope may resign freely, as Benedict XVI did in 2013. A pope who formally defected from the faith would, according to some theologians, cease to be pope — but this remains a theoretical question (CCC 882).
