Actually – NO.
The Church was being CALLED the "Catholic Church" by the end of the first century. We see this in the Letter to the Smyrnaeans by St. Ignatius – who was a student of the Apostle John and appointed Bishop of Antioch by Peter. He wrote the following – while the Apostle John was presumably STLIL alive.
Ignatius of Antioch
Follow your bishop, every one of you, as obediently as Jesus Christ followed the Father. Obey your clergy too as you would the apostles; give your deacons the same reverence that you would to a command of God. Make sure that no step affecting the Church is ever taken by anyone without the bishop’s sanction. The sole Eucharist you should consider valid is one that is celebrated by the bishop himself, or by some person authorized by him. Where the bishop is to be seen, there let all his people be; just as, wherever Jesus Christ is present, there is the Catholic Church (Letter to the Smyrneans 8:2 [A.D. 110]).
First, any info that Peter appointed Iggy to anything is quite-sketchy, & comes from many CC sources. And once Jesus ascended to heaven, there's not been any physical presence of Him that man knows of.
And here's a link to what Iggy's letter to Smyrna ACTUALLY SAYS ! https://www.orderofstignatius.org/files/Letters/Ignatius_to_Smyrnaeans.pdf
It’s STILL not called the “Roman” Catholic Church or “RCC”. Every Melkite, Maronite, Coptic, Byzantine, etc., Catholic would have a problem with you calling it that.
It is simply, “The Catholic Church”.
But the majority of the USA is NOT of the CC. And while Pres. Biden says he is, his pro-abortion stance says otherwise.
I'm a n indy fundy baptist, which is as much His Church as any other, and we've received ALL our intel about God & His commands to man from SCRIPTURE ONLY. If Granny told us, a pastor, a friend, or an at-large Christian, all ultimately got their info from ECRIPTURE.
I will give you the keys to the kingdom of heaven. WHATEVER YOU BIND on earth shall be bound in heaven; and WHATEVER YOU LOOSE on earth shall be loosed in heaven."
Matt. 18:18
Amen, I say to you, WHATEVER YOU BIND on earth shall be bound in heaven, and WHATEVER YOU LOOSE on earth shall be loosed in heaven.
Luke 10:16
Whoever listens to YOU listens to ME. Whoever rejects YOU rejects ME. And whoever rejects ME rejects the ONE who sent ME."
The fact that YOU have a problem with God's will is irrelevant . . .
So, what else did Peter do but preach?
Soooo, WHICH days would those be?
2nd century?
3rd century?
During his lifetime.
As a Sola Scripturist –
YOU will have to show me where the
BIBLE says that
2 Thess. 2:15 has
“expired”.
You
can’t because Sola Scriptura is a
self-defeating doctrine because it can’t even prove
ITSELF . . .
You will also have to show me where there were NO sinful people in Christ's Church at ANY time in history. Jesus Himself chose a DEVIL to be one of His Apostles (John 6:71).
I eagerly await your findings . . .
Jesus DELIBERATELY chose Judas. And in the past, legitimate churches took steps to purge evildoers from their ranks, rather than launch cover-ups to try to keep the evil from becoming public.
I believe you know, but won't admit, that any of the last few popes could've taken swift, drastic, authoritative ACTION to have ended most of the recent scandals before they grew. Long as the RCC continues its ridiculous "celibacy for clergy" practice, there'll be those who give in to sexual aberrations, but the pope could swiftly make an end of the problem & compensate its victims in one day if he chose.
Now, may we get back to the subject, that Easter was not on Sunday this year ?
