Why would one wish for the demise of the Catholic Church? If one is dissatisfied with it and desires it to be re-born then there are several examples of Christians 'freeing' themselves from it's "contrived and Sacramentally-imposed bondage" throughout history.
Mind you, these supposed 'free Christians' have spent the last 500 years 'freeing' themselves from the 'bondage' they have been continually imposing on each other. There are now 40,000 or so sects of such 'free Christians' throughout the world; quite a 'menu' to choose from for anyone so dissatisfied with his own Church that he/she advocates it's demise.
It beats me why today's dissidents if their unhappiness with the Catholic Church of is so great, don't have the courage of their convictions as Luther et al did and start their own religion.
