You condemn others interpretations of scripture as if they are wrong and hold your interpretations of scripture are right.
On what basis? Because you say you are guided by The Holy Spirit in your interpretation.
You are claiming infallibly in your interpretations of Scripture, yet when asked, you say you aren’t infallibly guided.
All the Fathers you mention were Catholic Bishops. The Catholic Councils that determined the Canon referred to these fathers for the transmission of authentic scriptures from the Apostles.
The Catholic Councils used its own lineage of bishops to determine the Canon. Those bishops were the authenticators of the Scriptures handed down.
“…to be in honour however with the Catholic Church for the ordering of ecclesiastical discipline…one to the Laodicenes, another to the Alexandrians, both forged in Paul’s name to suit the heresy of Marcion, and several others, which cannot be received into the Catholic Church; for it is not fitting that gall be mixed with honey. The Epistle of Jude no doubt, and the couple bearing the name of John, are accepted by the Catholic Church…But of Arsinous, called also Valentinus, or of Militiades we receive nothing at all.” The fragment of Muratori (A.D. 177).
The Catholic Church knew what books were handed on in the lineage bishops, and which were forgeries, those not continuously handed on through the bishops.
Clement was bishop of Rome in the first century. We see him talk of Apostolic succession.
“And thus preaching through countries and cities, they appointed the first-fruits [of their labours], having first proved them by the Spirit, to be bishops and deacons of those who should afterwards believe. Nor was this any new thing, since indeed many ages before it was written concerning bishops and deacons. For thus saith the Scripture a certain place, ‘I will appoint their bishops s in righteousness, and their deacons in faith.’… Our apostles also knew, through our Lord Jesus Christ, and there would be strife on account of the office of the episcopate. For this reason, therefore, inasmuch as they had obtained a perfect fore-knowledge of this, they appointed those [ministers] already mentioned, and afterwards gave instructions, that when these should fall asleep, other approved men should succeed them in their ministry…For our sin will not be small, if we eject from the episcopate those who have blamelessly and holily fulfilled its duties.” Pope Clement, Epistle to Corinthians, 42, 44 (A.D. 98).
“For what is the bishop but one who beyond all others possesses all power and authority, so far as it is possible for a man to possess it, who according to his ability has been made an imitator of the Christ off God? And what is the presbytery but a sacred assembly, the counselors and assessors of the bishop? And what are the deacons but imitators of the angelic powers, fulfilling a pure and blameless ministry unto him, as…Anencletus and Clement to Peter?” Ignatius, To the Trallians, 7 (A.D. 110).
Notice Ignatius disciple of John mentions the lineage of the bishops of Rome, Anecletus, Clement, Peter.
“Hegesippus in the five books of Memoirs which have come down to us has left a most complete record of his own views. In them he states that on a journey to Rome he met a great many bishops, and that he received the same doctrine from all. It is fitting to hear what he says after making some remarks about the epistle of Clement to the Corinthians. His words are as follows: ‘And the church of Corinth continued in the true faith until Primus was bishop in Corinth. I conversed with them on my way to Rome, and abode with the Corinthians many days, during which we were mutually refreshed in the true doctrine. And when I had come to Rome I remained a there until Anicetus, whose deacon was Eleutherus. And Anicetus was succeeded by Soter, and he by Eleutherus. In every succession, and in every city that is held which is preached by the law and the prophets and the Lord.'” Hegesippus, Memoirs, fragment in Eusebius Ecclesiatical History, 4:22 (A.D. 180).
So by the time Catholic Church canonised the Bible at the council of Rome, they had a list of books continuously attested to and vouched for by preceding Bishops to the first century, and continuously used in their churches.
That is why the Bible is a product of Catholic Tradition.
All the writings of the Fathers come down to us through the Catholic Church because the Fathers were Catholics.
