No, since you added books to the Bible, you are the ones that show contempt for it.
Even many of your own theologians, before Trent, did not regard those books as Canonical.
As for 'tradition' the tradition that Paul is speaking of is the tradition he gave to the church, that is the example that he showed.
Christ condemned tradition when it is used to supplant or undermine scripture (Mk.7:7-3)
Nonsense. Show me a bible prior to the Reformation that does not have the disputed books. The Canons of Hippo and Carthage list them (late 4th and early 5c).
