Many people, including Catholics, might be surprised to find that they can open any authentic version of the Bible and find where Jesus created the Catholic Church! The Gospel of Matthew records it perfectly where Jesus tells the apostles: "Go ... and make disciples of all nations, baptizing them in the Name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and behold, I am with you always, to the close of the age"(Mt 28:18-20). You don't see the word "Catholic"? Keep reading...
Jesus gave his Church a mission ... and that is what gives the Church her identity. Christ gave his Church a "universal" mission. "Catholic" is translated from the Greek word "Katolokos" which means "universal". Therefore, Christ gave his Church a Catholic (Universal) mission - to evangelize all nations and to baptize them into God's family.
Although the word "Catholic" does not explicitly appear in the text, her mission certainly does, and it's her mission that gives the Church her identity...not a sign hanging below the Church's steeple with "Catholic Church" painted on it. It might be interesting to note that neither of the words "Incarnation" or "Trinity" appear in the Bible, either, yet no authentic Christian argues against their essence in the Bible.
"Wherever the bishop shall appear, there let the multitude of the people also be; even as wherever Jesus Christ is, there is the Catholic Church."--St. Ignatius of Antioch (A.D. 110)
