Kevin, I know exactly what you mean. I was raised Catholic and, although I have been non-practicing for many years, I still identify more as a Catholic than not.
Actually, I have been feeling like something was "missing" (spiritually) for the past few years and had been thinking a lot about starting to go to church again. Regardless, I always had the comforting feeling that the Church was there, just as it had been for the past 2000 years, ready for me whenever I chose to return. Now, I don't feel that way, and it feels very sad and very scary.
I've certainly had problems with many of the Vatican's positions over the years--women in the priesthood, contraception, gays--but I knew that many Catholics, and even priests, didn't agree with these views either and tended to practice Catholicism on a more "local" level whereby these issues were tempered with a more realistic worldview. It was a compromise that most people could live with.
The pedophile issue, however, is the last straw for me. As you pointed out, it's not the fact that the pedophilia occurred, but the Church's willingness to cover up and enable behavior which is immoral, unethical, and illegal; that it actually facilitated repeated child abuse and now seems either unable or unwilling to even admit it was wrong, much less admit that decisive action needs to be taken to stop it. I have known for many years--hell, what Catholic hasn't known since Vatican II?--that Rome was seriously out of touch with the rest of the world--but this goes beyond that. I honestly cannot imagine what anyone in Rome could possibly be thinking to convince themselves that this is all okay and no big deal.
Add to that the fact that the pope is clearly very ill and incapacitated, but refuses to step down...well, I just can't believe they don't understand how many US Catholics they have lost permanently, and are continuing to lose, over issues like this.
FWIW, my parents are such staunch Catholics that when they asked me my opinion of all this last time I was home, I was actually quite hesitant to speak my mind, thinking they might feel compelled to defend the Church. I should've given them more credit. They are furious about all of it and agree with every one of my views. They do still attend their tiny local parish church, because they like the congregation and I gather the priest has made it clear, if not in so many words, exactly what he thinks Rome should be doing. They tell me, however, that hundreds of thousands of Catholics across the country are registering their protests in the collection basket--it's become common for folks to drop, rather than money, notes which read something like, "We'll start donating money again if and when the Vatican starts taking responsibility for its actions."
I still believe that the Roman Catholic Church is the one true church, entrusted to Peter by Jesus. And I am extremely hurt, and angry as hell, that men who consider themselves God's agents here on earth have corrupted it so terribly.
