John Paul II does. He has devolved authority in certain areas to the national bishops conferences (Friday abstinence, observance of certain Holy Days on Sundays, communion in the hand, and other liturgical matters). Of course, no episcopal conference can bind an individual bishop, but they do tend to express consensus through those conferences.
What is the relation between the...ahem...consensus of the latest missive on receiving Holy Communion by pro-abortion cheerleaders and the authentic teaching of the Catholic Church??? Can you campaign to harvest embryonic stem cells with wild abandon on Saturday and receive Our Lord on Sunday in good conscience? How does that make ANY sense???
