Oral Tradition in the New Testament by David Palm

Does any New Testament author cite oral tradition as authoritative for doctrine? -- http://www.chnetwork.org/journals/sola/sola8.htm

This is a good question. :) I remember reading this almost 10 years ago now.

2 Thess 2:15 So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.
