I have a dear, life-long friend who is an ardent Roman catholic. (I'm talking Opus Dei ardent.) I read the CCC years ago so I could understand his position fully, and be able to back up claims like "no, it doesn't say 'represent' it says 're-presents' and that's a problem and here's why". The doctrine of 'implicit faith' creates something of an incentive to accept the 'trust me bro' of the priests.
