Nonsense. Here you make the beginner's mistake of relying on an English language dictionary---rather than a theological dictionary---for your (mis)understanding of "faith." Try again.
As usual, you completely miss the point. The "proof" I requested in reply to certain anti-Catholic claims was simply support from both Divine Revelation (in my opponent's case, "Scripture alone") and ecclesiastical history, since his/her claims were supposedly based upon both sources of information. If one is going to issue allegedly biblical and historical claims about the Catholic faith, one needs to be prepared to "prove" (demonstrate) his assertions from those particular sources. Sorry for your confusion, but you're off on a rabbit trail here.
