Last Sunday (May 15) in the Ordinary Rite it was "Good Shepherd Sunday," (it was the Sunday before last in the Extra-Ordinary Rite) and the Gospel reading was as follows:
“Amen, amen, I say to you,
whoever does not enter a sheepfold through the gate
but climbs over elsewhere is a thief and a robber.
But whoever enters through the gate is the shepherd of the sheep.
The gatekeeper opens it for him, and the sheep hear his voice,
as the shepherd calls his own sheep by name and leads them out.When he has driven out all his own,
he walks ahead of them, and the sheep follow him,
because they recognize his voice.
But they will not follow a stranger;
they will run away from him,
because they do not recognize the voice of strangers.”
Although Jesus used this figure of speech,
the Pharisees did not realize what he was trying to tell them.
So Jesus said again, “Amen, amen, I say to you,
I am the gate for the sheep.
All who came before me are thieves and robbers,
but the sheep did not listen to them.
I am the gate.
Whoever enters through me will be saved,
and will come in and go out and find pasture.
A thief comes only to steal and slaughter and destroy;
I came so that they might have life and have it more abundantly.”
And that name is "Catholic!" Jesus didn't build many churches, He built One Church (Matthew 16:18-19). Jesus desires that we BE one, just as He and the Father are One (John 17:11). That One Church, very early on got to be known as the Catholic Church - in fact the first use of the name "Catholic Church" was used by a disciple of St. John the Apostle, St. Ignatius of Antioch in his Letter to the Smyrneans writes:
Where the bishop appears, there let the people be, just as where Jesus Christ is, there is the Catholic Church. It is not permitted without authorization from the bishop either to baptize or to hold an agape; but whatever he approves is also pleasing to God.
The Apostle's Creed states:
I believe in the Holy Spirit, the holy Catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body and life everlasting.
St. Augustine in his Fundamental Letter Against Manicheaus writes:
The succession of priests keeps me, beginning from the very seat of the Apostle Peter, to whom the Lord, after His resurrection, gave it in charge to feed His sheep, down to the present episcopate. And so, lastly, does the name itself of Catholic, which, not without reason, amid so many heresies, the Church has thus retained; so that, though all heretics wish to be called Catholics, yet when a stranger asks where the Catholic Church meets, no heretic will venture to point to his own chapel or house.
Those who have ventured off, leaving the seat of St. Peter behind, are not fully part of (if at all) THE Church which Jesus Christ built. Those who have further ventured off and even attack and condemn the Catholic Church have removed themselves in equal and just measure from the One, True Church which Jesus Christ Himself built.
His Church is built upon the BISHOPS - the first 12 of whom were the Apostles (Judas being succeeded by Matthias in Acts 1). THE True Church is traced in valid apostolic succession to one of The Twelve. Outside of this succession all you have is an imposter church, a fraudulent church promoting lies and deception "to fool even the elect." These imposter churches DO possess a modicum of truth - which is why they are able to deceive so many - even claiming to be "Bible Believing," yet if this were completely so, they would be following a valid successor to one of the original Apostles - and their name would be "Catholic."
