I'm in the same state of mind.
My solution, if I can call it a solution, has been to withhold donations to anything connected to parties involved with the crisis. This includes everything from institutions parroting the "nothing to see here" line to parties who see no need to take action to purge the devil from our midst. They want our money. We can deny them. We are obligated to give money to charity, but not to unworthy causes.
I recently had the opportunity to contact a charity planning a gala featuring Cardinal Tobin as a keynote speaker, let them know I would not be donating to them if an individual like him was going to be involved, due to concerns about his role in the scandal. Money talks. If others did the same? One less revenue stream for these devils. Look at what Legatus just did and tell me that didn't cause some consternation in Rome. They probably had that money already spent!
In other matters I'm trying to get more serious, and visibly serious, about my own faith. These abuses of people and doctrine both seem to flourish when people are lukewarm cultural catholic types…. so why not get serious? Praying, fasting, reading the Bible more, but for myself, also wearing the veil to church. Wore it when I lectored at last week's mass; mind you NO ONE at this parish wears a veil, ever. Wouldn't you know later at work someone came up to me, told me it made them feel better to see it, and we had a great conversation about showing respect to God in his house!
Maybe this is what people had to do during the rise of Arianism. I'm not a clergyman empowered to do anything to fix the problem, but if I make it clear to those who ARE that I (and others) will stand with them, maybe it will move them to act.
