papal primacy

Roman Catholicism

Quick Summary

Papal primacy is the doctrine that the bishop of Rome, the pope, holds supreme authority over the entire Christian church. This belief is rooted in the Petrine theory, which interprets biblical passages, particularly Matthew 16:18-19, as Christ granting Peter unique authority, which is then passed down to his successors, the popes.1

Historically, the title of pope was initially used for any bishop, but by the 9th century, it was reserved for the bishop of Rome. Early Church Fathers, such as Leo I, began to articulate the theoretical basis for papal authority, viewing the pope as Peter's representative with monarchical powers. This doctrine was further developed through the Middle Ages and formally defined at the First Vatican Council in 1870, which declared the pope's judicial supremacy and infallibility in matters of faith and morals when speaking ex cathedra. While Vatican II affirmed papal primacy and infallibility, it also emphasized the authority of bishops as successors to the apostles, forming a college with the pope as its head.234
