First let’s look at the
definition of authority:
- the power to determine, adjudicate, or otherwise settle issues or disputes; jurisdiction; the right to control, command, or determine.
- a power or right delegated or given; authorization Who has the authority to grant permission?
- a person or body of persons in whom authority is vested, as a governmental agency.
What I will (hopefully

) show you is that each of these three definitions is fulfilled in the Catholic Church.
The first point we agree on, I believe, the Jesus Christ, as the Son of God, 1. is all-good, 2. is all-knowing; and 3. has all authority over us. Do you see that Christ’s authority is God’s authority, and that God’s authority comes from being the Creator of us all? Even more than as parents have authority over their children, God has all authority over us, and each of us, even tho many do not acknowledge His authority.
Christ has this authority, and He has an additional claim upon us, because He redeemed us. Because He redeemed us of us, we owe Him our allegiance, just as we would owe something to someone who saved our life.
Now, how does this relate to the Church? We see that Christ was incarnate and lived on earth, and that He had disciples whom He taught. He and His disciples travelled around Israel and taught others as well.
There came a time when this happened: Matthew 16: 18 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. [19] 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 upon earth, it shall be loosed also in heaven.
Wow, what a lot He said in just those few words!
He re-names Peter. Re-naming is always very significant in the Bible, but this name change does not come through in English all that well. Simon’s new name was literally Rock in Hebrew.
Then Christ said that upon this Rock, He would build His Church. Rock would be the foundation of Christ’s church on earth.
And this church which would be built on the foundation Rock would be protected by Christ’s promise in such a way that “the gates of Hell would not prevail against it.” What does this mean? That Christ promised that His Church would not lose to the powers of Hell, that Christ would never abandon His Church.
Now Christ returns to Rock, and tells him He will give him the keys to His kingdom. In the Old Testament, we see that the giving of the keys of the kingdom signified that someone was being made a vicar of that kingdom, that he was to rule for at least a time in the king’s place.
Note too that Rock alone (notice Christ uses the second person singular thou) is given a special power of binding and loosing: whatsoever thou shalt bind *on earth *shall be bound in Heaven…
So you can see that Christ invested Rock with great power, authority, over His Church. Rock was to be the vicar, ruling for the King, Christ, in His absence.
And you can see that Christ promised that the domain of the Prince of Lies would not prevail over the Church, so the teachings of the Church, which come directly from what Christ taught the Apostles, would be protected.
