Vatican II changed the fundamental orientation of the church from being a cult of God to being "a cult of Man", in the words of Paul VI.

Pope Francis himself, has telegraphed his ultimate goal of creating a false dichotomy between the "word of God" and the Eucharist so stay tuned.  You ain't seen nothing yet!
