Vatican II didn't JUST REMIND the laity of their role.  It was for the Whole Church.  Everyone must continue to grow.

But even Vatican II was the "Sum Total" of our Church in the life of humanity.  We're decades out of Vatican II.  And the world that we live in doesn't look like the 1960's any more.  The 1960's set the stage [indeed it is the ground level] of the world that we live in---but it's not the sum total.  

As baptized Catholics, we are anointed with Chrism as Priest, Prophet, and King on our baptism.  Being a Prophet---calls for the courage to not only speak out but also to act----for the greater growth of God's People.  

We don't live in a simple world anymore, either.  There are many categories----but all who fit into those categories, are members of Christ's one flock.
