The task is to determine what constitutes authentic tradition. How can we know which traditions are apostolic and which are merely human? The answer is the same as how we know which scriptures are apostolic and which are merely human—by listening to the magisterium or teaching authority of Christ’s Church. Without the Catholic Church’s teaching authority, we would not know with certainty which purported books of Scripture are authentic. If the Church revealed to us the canon of Scripture, it can also reveal to us the "canon of Tradition" by establishing which traditions have been passed down from the apostles. After all, Christ promised that the gates of hell would not prevail against the Church (Matt. 16:18) and the New Testament itself declares the Church to be "the pillar and foundation of the truth" (1 Tim. 3:15).
Ong's works also made possible an integrated theory of oral tradition which accounted for both production of content (the chief concern of Parry-Lord theory) and its reception.  This approach, like McLuhan's, kept the field open not just to the study of aesthetic culture but to the way physical and behavioral artifacts of oral societies are used to store, manage and transmit knowledge, so that oral tradition provides methods for investigation of cultural differences, other than the purely verbal, between oral and literate societies.
tradition , from . tradicion (1292), from L. traditionem (nom. traditio) "delivery, surrender, a handing down," from traditus, pp. of tradere "deliver, hand over," from trans- "over" + dare "to give" (see date (1)). The word is a doublet of treason (.). The notion in the modern sense of the word is of things "handed down" from generation to generation. Traditional is recorded from ; in ref. to jazz, from 1950. Slang trad, short for trad(itional jazz) is recorded from 1956; its general use for "traditional" is recorded from 1963.
