I thought my reply was clear: There's no such thing as scripture only or source only. So your point is moot.
Sola Scriptura says each individual plus scripture. In your case, you.
No, your reply was not clear. Paul said that anyone who taught something they didn't was to be considered accursed. No Catholic has shown an infallible source for what the apostles taught other than scripture. So unless you can show any other infallible source for what the apostles taught you leave us with nothing but scripture.
