It's a thing with tradition, too. I think most of us "regular" people are loathe to change the one thing that hasn't and shouldn't change greatly unless there is a legitimate reason - it's a connection with all that went before, sort of like an unending chain of rememberance.
Sometimes I think some priests have more in common with the closed world of academia than they do the world containing the unwashed masses. Most of the progressive bs has come out of academia - both political and religious. And it all seems to be somehow mysteriously intertwined.
