While Athanasius applauds tradition, it is still the same tradition which was taught in the scriptures, according to Athanasius...
The only thing Catholic in your post was your insertertion of the capital 'C' on the word catholic to make it look like good ole Athan was one of your boys...
There is nothing in your post that shows Athanasius leaning toward your religion...But quite the contrary...
"Wherefore keep yourselves all the more untainted by them, and observe the traditions of the Fathers, and chiefly the holy faith in our Lord Jesus Christ, which you have learned from the Scripture, and of which you have often been put in mind by me." Anthony of Egypt, Vita S. Antoni 89, (c. A.D. 350).
If that is what you took away from the Warning by Saint Athanasius (Cf. Encyclical Letter to the Bishops of Egypt and Lybia) then your reading compression skills need some work. Your research skills appear to be equally lacking. A wise person does not read a subject until he finds a clause that supports his preconceptions, he reads until he has read it all before concluding.
St. Athanasius is best remembered for his defense of Catholic doctrine against the Arian heresy that was defended by many because it was thought to be Scripturally based. This fight lead directly to the Council of Nicea, the documentation of Creeds that preceded the Canon of Scripture and ultimately to the production of a formal Canon.
'We are proving that this view has been transmitted from father to father, but ye, O modern Jews and disciples of Caiaphas, how many fathers can ye assign to your phrases? Not one of the understandings and wise; for all abhor you, but the devil alone; none but he is your father in this apostasy, who both in the beginning sowed you with the seed of this irreligion, and now persuades you to slander the Ecumenical Council, for committing to writing, not your doctrines, but that which from the beginning those who were eyewitnesses and ministers of the Word have handed down to us. For the faith which the Council has confessed in writing, that is the faith of the Catholic Church; to assert this, the blessed Fathers so expressed themselves while condemning the Arian heresy...' Athanasius, De Decretis 27 (c. A.D. 350).

There is nothing in what you have posted that changes what was the collective, comprehensive message of St. Athanasius or any of the other Early Church Fathers. So you can post a couple of paragraphs gleaned from a life time of writings that support your point, big deal. If I can choose the quotes I can make Barak Obama look conservative, Bill Clinton look virtuous and Pol Pot look like a humanitarian. Its really pretty simple to do and easy to detect when seen. All that is required is an actual knowledge of the truth and the nonsense lights up like a Christmas tree.
Peace be with you.
