Since my initial post, I wrote to my parish priest twice in an attempt to find out how he holds regarding wearing a kippah at mass. He did not respond.
Sadly, the vast majority of my emails to bishops and priest go unanswered. This surprises me every time, because I correspond with some of the most important Orthodox rabbis in the world and they answer me. Sometimes, they even call me on the phone.
I often wonder whether the failure of Catholic priests and bishops to respond has something to do with clericalism. I hope not.
