text: I'm not sure that I understand what you are saying.
  "We pick and choose what to criticize, what to affirm, among Papal teachings, but we are not Cafeteria Catholics?"  If you are quoting me, then I am unaware that I wrote that anywhere. If not then who's 'we'?
  Vatican I said the pope was infallible when he spoke definitively as the successor of Peter, on matters of Faith and Morals and I accept that without reservation. 
  If, however, one pope contradicts a predecessor, doesn't that obviate what you quote from Dei Verbum; contradicting is not 'handing on'. So which pope ought one to believe? St John Paul II who in Familiaris Consortio absolutely forbade the divorced and remarried to receive Communion, this praxis going back to Apostolic times. Or Pope Francis who appears to be saying that in certain circumstances they now can.
  The Assisi meetings can be regarded as personal initiatives of the two popes which the faithful are at liberty to express their approval or disapproval.
