Had you read and understood my previous replies, you’d understand that I do not.
I initially thought you’d made a mistake which was why I gave you a smiley. Then I realized you might actually be serious. So, you’re a Calvinist - just an assumption - as they used to tell us we weren’t Christian when we were growing up - they also told us we were the spawns of satan, and whores of Babylon, blah, blah, blah. lol
Regulator, seriously have you never wondered where the word Catholic comes from, and what it means? Why don’t you “interview” the very first Christians and see what they thought of the Church and the word Catholic? I suggest you start with our second bishop after St Peter - Ignatius of Antioch - as he was the first Christian to use it. (It was actually in Antioch, where the believers in Christ were first called Christians (cf. Acts 11:26).)
Ignatius wrote while on his way to Rome to be martyred -
“You must all follow the bishop as Jesus Christ follows the Father, and the presbytery as you would the apostles. Wherever the bishop appears, let the people be there; just as wherever Jesus Christ is, there is the Catholic Church” (Epistle to the Smyrnaeans 8).
Then interview Polycarp, bishop of Smyrna, who used the word many times. Polycarp was a disciple of the apostle John just as John was a disciple of Jesus. Like Ignatius, Polycarp suffered the martyr’s death in a coliseum in A.D. 155. In the Martyrdom of Polycarp, written at the time of Polycarp’s death - one example -
“The Church of God that sojourns in Smyrna, to the Church of God that sojourns in Philomelium, and to all the dioceses of the holy and Catholic Church in every place” (Epistle of the Church at Smyrna, preface).
Augustine in the fourth century, relying on Tradition of the early Church, is very clear in his terminology -
“We must hold to the Christian religion and to communication in her Church, which is Catholic, and is called Catholic not only by her own members but even by all her enemies” (The True Religion 7, 12).
And again, “The very name of Catholic, which, not without reason, belongs to this Church alone, in the face of so many heretics, so much so that, although all heretics want to be called Catholic, when a stranger inquires where the Catholic Church meets, none of the heretics would dare to point out his own basilica or house” (Against the Letter of Mani called “The Foundation” 4, 5).
Like Augustine, and those before, we continue the unbroken Tradition.
The early usage and importance of the word is said to this day at Mass - in the Apostle’s Creed and the Nicene Creeds. If you were a Christian in the first millennium, you were a Catholic, and if you were a Catholic you recited the Creeds affirming the “one holy, catholic, and apostolic Church.”
Lots more...just do some reading because after that there’s still the Biblical understanding of the word Catholic to come - with 2,000 years of history it’s difficult for anyone to reinvent the wheel.
