I have followed these arguments about more "democracy" in the Roman Catholic Church for some time.  The lack of theological grounding is very annoying.  Lay people being involved in church governance starts with one's theological understanding of baptism and ministry.  It's not about democracy, it's about how you understand what participation in the Body of Christ means.  Please somebody, bring some theology into this argument.  I recommend John Zizioulas Being as Communion.
