Kevin:  Whenever you equate "the full value of her (i.e. RCC) teachings" with the teachings of Christ and His gospel, you are teetering on the precipice of Rome's vaunted Pre-VII dominion theology.  Human frailty is a fact of life as mortal beings, not a failing of the "demands" of RC moral theology.  It seems you are a willing victim in Rome's desire to control you through your "perceived" failings, which will always be present with or without her "infallible" teachings.  IMO (although I can't take credit for it's genesis), the RCC has capitalized on man's unfailing penchant for weakness and frailty which, ironically, binds us to an institution rather than liberates the spirit... indeed, a remarkable system of bondage from cradle to grave.

You speak a lot about self justification--while I agree this does exist but so does, in fact, a rather boorish, self-referential quality among traditional Catholics--a result of placing one's faith in Rome's teachings versus the living Christ.
