wrote “catholic church”?
It wasn’t just Ignatius and it is clear that they agree with Protestant scholar N. D. Kelly:
"The church of God that sojourns at Smyrna, to the church of God sojourning in Philomelium - and to all of the congregations of the
holy and Catholic Church in every place." St. Polycarp, “The Martyrdom of St. Polycarp,” c. 135 A.D.
“Our Lord Jesus Christ is the Savior of our souls, the Governor of our bodies, and the
Shepherd of the Catholic Church throughout the world.” St. Polycarp, “The Martyrdom Of St. Polycarp,” c. 135 A.D.
“The Catholic church is one.” St. Victorinus, “Against Arius,” c. 280 A.D.
** “It is called Catholic then because it extends over all the world, from one end of the Earth to the other**; and because it teaches universally and completely one end and all the doctrines which ought to come to men’s knowledge, concerning things both visible and invisible, heavenly and earthly…” St. Cyril of Jerusalem, “Catechetical Lectures,” c. 350 A.D.
“Let us note that the very tradition, teaching,
and faith of the Catholic Church from the beginning, which the Lord gave, was preached by the Apostles, and was preserved by the Fathers.
On this was the Church founded; and if anyone departs from this, he neither is nor any longer ought to be called a Christian.” St. Athanasius, “Four Letters to Serapion of Thmuisc,” c. 360 A.D.
“Where was [the heretic] Marcion, that shipmaster of Pontus, the zealous student of Stoicism? Where was Valentinus, the disciple of Platonism? For it is evident that those men lived not so long ago—in the reign of Antonius for the most part—
and that they at first were believers in the doctrine of the Catholic Church, in the church of Rome under the episcopate of the blessed Eleutherius…” Tertullian 200 AD
“They alone have remained outside [the Church] who, were they within, would have to be ejected.
. . . hey vainly flatter themselves who creep up, not having peace with the priest of God, believing that they are secretly in communion with certain individuals.
For the Church, which is one and catholic, is not split or divided, but is indeed united and joined by the cement of priests who adhere to one another” Cyprian of Carthage 253 AD
Council of Nicaea I
“But those who say: ‘There was [a time] when he [the Son] was not,’ and ‘before he was born, he was not,’ and ‘because he was made from non-existing matter, he is either of another substance or essence,’ and those who call ‘God the Son of God changeable and mutable,’
these the Catholic Church anathematizes” (Appendix to the Creed of Nicaea [A.D. 325]).
“Concerning those who call themselves Cathari [Novatians], that is, ‘the Clean,’ if at any time
they come to the Catholic Church, it has been decided by the holy and great council that, provided they receive the imposition of hands, they remain among the clergy.” (Canon 8).
"
Concerning the Paulianists who take refuge with the Catholic Church, a decree has been published that they should be fully baptized…after being baptized, let them be ordained
by the bishop of the Catholic Church" (Canon 9).
** “[The Church] is called catholic, then, because it extends over the whole world, from end to end of the earth, and because it teaches universally and infallibly** each and every doctrine which must come to the knowledge of men, concerning things visible and invisible, heavenly and earthly, and because it brings every race of men into subjection to godliness, governors and governed, learned and unlearned, and because it universally treats and heals every class of sins, those committed with the soul and those with the body, and it possesses within itself every conceivable form of virtue, in deeds and in words and in the spiritual gifts of every description” Cyril of Jerusalem 350 AD
The Apostles’ Creed
“I believe in the Holy Spirit,
the holy catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting. Amen” (Apostles’ Creed [A.D. 360 version, the first to include the term “Catholic”]).
