The forum, the internet and Roman Catholic libraries are filled with links like this one which state clearly that Roman Catholics believe in at least 21 REASONS TO REJECT SOLA SCRIPTURA
As a quick antidote to the above link, let me quickly add...
As difficult as it is for some to pass up an opportunity to shriek "Rome, Rome" or to fabricate an insult of Catholicism this thread really wasn't about the validity or merit of Sola Scriptura. It would, however, be a shock if the usual suspects could demonstrate the concept of contextual communications and not give in to their guttural instincts and programming.
