The Church Is Catholic (Matt. 28:19–20, Rev. 5:9–10, CCC 830–856)*
Jesus’ Church is called catholic (“universal” in Greek) because it is his gift to all people. He told his apostles to go throughout the world and make disciples of “all nations” (Matt. 28:19–20).*
For 2,000 years the Catholic Church has carried out this mission, preaching the good news that Christ died for all men and that he wants all of us to be members of his universal family (Gal. 3:28).*
Nowadays the Catholic Church is found in every country of the world and is still sending out missionaries to “make disciples of all nations” (Matt. 28:19).
The Church Jesus established was known by its most common title, “the Catholic Church,” at least as early as the year 107, when Ignatius of Antioch used that title to describe the one Church Jesus founded. The title apparently was old in Ignatius’s time, which means it probably went all the way back to the time of the apostles.*

If we wish to locate the Church founded by Jesus, we need to locate the one that has the four chief marks or qualities of his Church. The Church we seek must be one, holy, catholic, and apostolic.*
The Church Is One (Rom. 12:5, 1 Cor. 10:17, 12:13, CCC 813–822)*
The Church Is Holy (Eph. 5:25–27, Rev. 19:7–8, CCC 823–829)*
The Church Is Catholic (Matt. 28:19–20, Rev. 5:9–10, CCC 830–856)*
The Church Is Apostolic (Eph. 2:19–20, CCC 857–865)*
Pillar of Fire, Pillar of Truth
Man’s ingenuity cannot account for this. The Church has remained one, holy, catholic, and apostolic—not through man’s effort, but because God preserves the Church he established (Matt. 16:18, 28:20).*
He guided the Israelites on their escape from Egypt by giving them a pillar of fire to light their way across the dark wilderness (Exod. 13:21). Today he guides us through his Catholic Church.*
The Bible, sacred Tradition, and the writings of the earliest Christians testify that the Church teaches with Jesus’ authority. In this age of countless competing religions, each clamoring for attention, one voice rises above the din: the Catholic Church, which the Bible calls “the pillar and foundation of truth” (1 Tim. 3:15).*
Jesus assured the apostles and their successors, the popes and the bishops, “He who listens to you listens to me, and he who rejects you rejects me” (Luke 10:16). Jesus promised to guide his Church into all truth (John 16:12–13). We can have confidence that his Church teaches only the truth.
