"Pierre Julien" WAS a a French sculptor who worked in a full range of rococo and neoclassical styles

quotes: "Do you know anything aside from plagiarizing? Have you studied ecclesiology for you to understand collegiality at supremacy?"

"Do you really know what the meaning of the motu propio is for you to say that it contains is absolute and binding?"

"All you know is rubricism."

Thanks!
