Part 2 
At Vatican II, there was a very different 'play-book'' used.  The vast amount of scholarly work carried out by eminent Catholic theologians over a number of decades leading up to Vatican II provided enough evidence to the bishops that there was a solid justification to embrace the major shifts in Church doctrine and practice.  One of these areas is found in "Gaudium et spes" [approved on December 7, 1965, by a vote of 2,309 to 75]. which stressed the limited competence of church leaders in the life of the church and in society.  There is a humility in the description of church leadership that leads to a recognition of the need for a greater role for the laity and a shared sense of responsibility for the development of ecclesial and social life [GS 43].  

The papacies of JP II and Benedict---were marked by revanchist policies where the major reforms of Vatican II---collegiality, subsidiarity, and synodalism were pushed away, rejected, or 'double-talked' out of existence.
