Am I trustworthy? I hope so; after all, I must answer to myself, not to a bishop; I can’t be absolved or indulged by another person; my conscience is my own burden, and can’t be lifted off me by some man with a miter and a ring.
I'm not sure I understand the connection you're drawing between those things and your trustworthiness. In fact, what's the relevance of the distinction you're presumably trying to draw between yourself and a priest? A priest must answer to himself just like you do; he also has to answer to a bishop - just like you and I have other people and institutions we must answer to in various contexts. Moreover, a priest's conscience is presumably his own as much as ours are. His conscience isn't lifted simply by a mitre and a ring; according to what they believe, it requires contrition, confession and satisfaction - which doesn't seem much different from what I daresay most people believe ought to be prompted by a guilty conscience. (If there's a difference in that respect, it might be that the priest has an additional external duty to do so, that you and I don't have.)
Conversely, no one has promised me that he’ll be obedient or celibate. I feel no obligation to protect such people; my prestige isn’t involved in their trustworthiness, and if they step sideways my standing among my peers isn’t lessened.
Yet presumably there are people who do make explicit or implicit commitments to you in your line of work or in your life generally, people for whom - all things being equal - you feel inclined to look out, whose conduct might be seen to reflect on you, and so forth. Just a different context. Where are you going with this point? And how does this relate to the issue of clerical trustworthiness?
I think, given human nature, that the rather feudal relationship between a priest and his bishop will incline the latter to protect the former. Consider it in Mafia-esque terms:
“Hey, Bish! You man been puttin’ moves onna altar-boys! ‘At’s notta nice! What, you can’ keep you boys in line? You can’ deliver on you own turf?”
I'm not sure that's an accurate characterization of the relationship between a priest and his bishop; and of course the bishop has an independent set of duties to the altar boys too.
Now what’s Bish likely to do? What’s his boy going to expect from him? A move to another parish, a letter or two lost in the files – that’s not much between master and man.
By and large, while there is abundant evidence that this occurred in some dioceses with certain priests, there is little to suggest that it would be Bish's likely response in any era (and strikes me as highly improbable now). [ETA: Now, if you'd made Bish a public school superintendent, that might be a slightly different story ...]
How does this relate to the question of the untrustworthiness of priests? And is clerical sexual abuse even an appropriate context to make a general evaluation, given its rarity and the extreme unlikelihood that this would be an issue for any given priest?
