Great insight and too true. It's like they're playing little games, slightly or enormously changing the rules so that their pride can show. Creating something new to be remembered by instead of remembering that we come to worship God and His Son, Jesus Christ and that is what is to be remembered. The priest, the liturgist, the musician should fade into the background and present Christ instead of themselves and their egos.
This is one reason I prefer the old Mass -- there was a lot less scope for "individual expression." Granted, many priests say the new Mass devoutly and without self-aggrandizement, but with some of them I get the feeling that the Mass is distracting me from the Mass!
Yeah, just like a boil on your butt.
