For terycarl to answer, since no other Catholic to date has taken a stab at it....
Just what are those traditions Paul was referring to that he handed down that we are to keep that were not included in Scripture?
How do you know?
How do you know they’re from the apostles, Paul in particular?
How do you know they’ve been passed down faithfully?
What is your source for verifying all of the above?
