Update

I called the diocese, where I talked to a very sensible associate superintendent. "What's the most productive way for me to proceed here?" I asked him. He had an excellent suggestion for me: request a meeting with the chaplain (he advised me to mention his name in my request), and ask the chaplain to think about ways to address the school culture issue together with the theology faculty. He wants to know what happens. He struck exactly the right note, you guys, and I am feeling much less like setting something on fire or flouncing over to the school to withdraw my boys. I'll keep you posted.
