Can you elaborate on paradosis?
I am a litte familiar with the concept in the sense of traditions which, of course, Paul would have have known and lived.
Paradosis, in the New Testament context, is a passing on of a tradition. The word is used to refer to oral teachings both positively (3 times) and negatively (5 times).
What we can take from this is that "Tradition" itself is not categorically condemned, but rather what the content and origin of that Tradition is. This will be hotly contested in these threads because the categorical condemnation of Tradition is essential to Sola Scriptura Protestantism.
I also mentioned the word "kerygma" because it is the proclamation of a religious truth. The Church teaches that the paradosis of the New Testament IS kerygma.
