Hey Big Dummy here is a good example that represents the rest of the quotes you provided:
“The Holy and Divinely inspired writings are sufficient of themselves alone to make known the truth” (Athanasius 296-373, Orat. Contr. Gent. Tom. I).
Are you of the opinion that Athanasius believed that the "Holy and Divinely inspired writings, being sufficient of themselves alone to make known the truth” - were to be interpreted by the church or by each and every individual?
If the individual outside church and tradition then are you really sure about that considering the following quotes from Athanasius?
The same can be said about all the other quotes you provided:
“The confession arrived at Nicaea was, we say, more SUFFICIENT and ENOUGH BY ITSELF, for the subversion of all irreligious heresy, and for the security and furtherance of the doctrine of the Church” Ad Afros 1
“But the WORD OF THE LORD which came THROUGH the Ecumenical Synod at Nicaea, abides forever” Ad Afros 2
“…forcing on the divine oracles a misinterpretation according to their [the heretics] OWN PRIVATE sense” Orat 1,37
“…that He was not before that time, but is wholly man by nature and nothing more. But this is NO sentiment of the CHURCH, but of the Samosatene and of the present Jews…” Orat 1,38
“This then I consider the sense of this passage, and that, a VERY ECCLESIASTICAL sense.” Orat 1,44
“Who heard in his FIRST CATECHISING, that God has a Son and has made all things by His proper Word, BUT understood it in THAT SENSE in which we now mean it? Who on the rise of this odious heresy of the Arians, was not startled at what he heard, as strange” Orat 2,34
“However here too they (Arians) introduce their private fictions, and contend that the Son and the Father are not in such wise ‘one,’ or ‘like,’ as the CHURCH preaches, but as they themselves would have it” Orat 3,10
“If we now consider the OBJECT of that FAITH which we Christians HOLD, and using it as a RULE, apply ourselves, as the Apostle teaches to the reading of inspired Scripture. For Christ’s enemies, being ignorant of this OBJECT, have wandered from the way of truth, and have stumbled on a stone of stumbling, thinking otherwise than they should think” Orat 3,28
“Let us, retaining the GENERAL SCOPE of the faith, acknowledge that what they interpret ill, has a RIGHT interpretation” Orat 3,35
“Had Christ enemies thus dwelt on these thoughts, and recognized the ECCLESIASTICAL SCOPE as an ANCHOR for the faith, they would NOT have made SHIPWRECK of the faith…” Orat 3,58
“We are content with the fact that this is not the teaching of the Catholic Church, nor did the Fathers hold this.” Epis 59
“But our faith is right, and starts from the teaching of the Apostles and TRADITION of the FATHERS, being confirmed both by the New Testament and the Old.” Epis 60
“But after him (the devil) and with him are all inventors of unlawful heresies, who indeed refer to the Scriptures, BUT DO NOT hold such opinions as the SAINTS HAVE HANDED DOWN, and receiving them as the traditions of men, err, because they DO NOT rightly KNOW THEM nor their power” Festal Letter 2
“Scarcely, however, did they begin to speak, when they were condemned, and one differed from another; then perceiving the straits in which their heresy lay, they remained dumb, and by their silence confessed the disgrace which came upon their heterodoxy. On this the Bishops, having negatived the terms they had invented, published against them the SOUND and ECCLESIASTICAL faith…And what is strange indeed, Eusebius of Caesarea in Palestine, who had denied the day before, but afterward subscribed, sent to his Church a letter, saying that this was the CHURCH’S faith and the TRADITION of the FATHERS” De Decretis 3
“Are they not then committing a crime in their very thought to gainsay so GREAT and ECUMENICAL a Council?” De Decretis 4
“For, what OUR FATHERS have delivered, THIS IS TRULY DOCTRINE; and this is truly the TOKEN of doctors, to CONFESS THE SAME THING with each other, and to vary NEITHER from themselves nor from their FATHERS…Thus the Greeks, as not witnessing to the SAME doctrines, but quarreling one with another, have no truth of teaching; but the holy and veritable HERALDS OF TRUTH AGREE TOGETHER, and do not differ…preaching the same Word harmoniously” De Decretis 4
