Rather, what needs to end NOW is using the existence of oral teaching to sanction whatever Rome says is the word of God from it. You thus invoke texts such as 2Thes,. 2:15 as supporting another stream of Divine revelation, which we are to believe Rome reveals, and thus we must place implicit faith in the one true church in order to know what Paul was referring to her.
And that we must reject the reasonable premise that he was doing what SS can do, that of enjoining obedience to the oral preaching of Scriptural Truths, subject to examination by Scripture as apostolic preaching was by noble souls, (Acts 17:11, or that Paul was preaching wholly inspired new revelation, which the Catholic magisterium dare not claim to do, and that it was not subsequently written, as was the norm with anyone called the word of God/the Lord.
Catholicism, both Roman and EO, holds that Oral Tradition only refers to oral teaching that she declares is the word of God, and equates this with Scripture, but this position is under the premise that she discerns what parts of oral teaching is the binding word of God, as well as what parts of written teaching are.
It is the Church that tells us what is Scripture, and it is also the Church that tells us how Scripture is to be understood...The decisive test and criterion for our understanding of what the Scripture means is the mind of the Church http://oca.org/scripture/how-to-read-the-bible; — http://orthodoxinfo.com/phronema/ware_howto.aspx
People cannot discover the contents of revelation by their unaided powers of reason and observation. They have to be told by people who have received in from on high. - Cardinal Avery Dulles, SJ, "Magisterium: Teacher and Guardian of the Faith, p. 72;
the believer cannot believe in the Bible nor find in it the object of his faith until he has previously made an act of faith in the intermediary authorities..." - Catholic Encyclopedia>Tradition and Living Magisterium;
Which means both Scripture and Oral T only authoritatively consist of and mean what she says, and thus they cannot contradict her. And then Caths reference them to support that she alone is the infallible authority that decides what is of God.
Some thus appeal to Scripture merely as a historical document by which one can discern that their church is the only entity that can tell us that Scripture is the word of God. But if one can discern this church as the one true infallible one then they can also discern that she is not, which destroys the reason what the Caths argue we must have an infallible interpreter.
The Fact is that only part of Scripture first was orally expressed as the word of God, including a minority of the NT, and not all that grows in the ground of oral teaching is valid truth much less wholly inspired of God (unless you want to sanctify the Talmud as being so), and Scripture represents wheat out of that produce.
And Divine writings were discerned and held as assuredly being of God before there ever was a church of Rome which presumed that she was essential for this, with the basis for their establishment basically being essentially due to their unique heavenly qualities and attestation.
