Indeed, "willfully refuse" which mean immoral!  As the Royal Australian Commission investigating clerical sexual abuse points out that there is substantive problems with RCC clericalism.

Tweaking accidental items is poorly treating symptoms.  
"Popes come, popes go, the curia remains."  The curia need not be reformed as eliminated but that ain't gonna happen to Constantine's church. It is reported in Nazareth that Jesus gave up membership, too!
